[Effect of localization of pulmonary arterial changes on echocardiographic indices of right heart function and their correlation with exercise capacity: comparison of arterial and thromboembolic pulmonary hypertension].

AIM: To assess correlation between exercise tolerance and Doppler-derived indices of right ventricular (RV)--pulmonary arterial coupling in patients with different location of vascular lesions causing pulmonary hypertension (PH). MATERIAL: 45 patients: 21 with thromboembolic (TE-PH) and 24 with arterial PH defined as systolic pulmonary arterial pressure (SPAP) > 40 mm Hg. The two groups were similar as far as SPAP (74,8 +/- 15,2 vs 76.5 +/- 14,1 mm Hg, p = ns) and distance covered during 6 minute walk test (339 +/- 116 vs 320 +/- 127, p = ns) are concerned. RESULTS: Flow velocity curve in the RV outflow tract were different in the two groups. Time from onset to peak velocity of ejection (acceleration time, AcT) as well as to midsystolic deceleration were shorter in TE-PH then in arterial PH (59.0 +/- 6.3 vs 68.1 +/- 15.4 msec, p = 0.015 and 123.8 +/- 17.9 vs 137.9 +/- 29.7 msec, p = 0.071, respectively). In the whole studied group as well as in arterial PH significant correlation between exercise tolerance and Doppler-derived indices of RV--pulmonary arterial coupling were found (r = 0.51, p < 0.001 and r = 0.72, p = < 0.001, respectively). Interestingly, no such relationship was found in TE-PH, (r = 0.16, p = ns). CONCLUSION: In contrast to arterial PH, pressure wave prematurely reflected from the intraluminal thrombi seem to disturb the RV ejection pattern and its correlation with exercise tolerance in TE-PH. Whether progression or effects of treatment on arterial PH can be assessed by monitoring changes in Doppler-derived indices of RV--pulmonary arterial coupling requires further studies.

[Effect of long-term therapy with oral Beraprost on survival of patients with arterial and inoperable thromboembolic pulmonary hypertension].

Beraprost sodium (BPS)--an orally active prostacyclin analogue--improves haemodynamic parameters and quality of life in group of patients with pulmonary arterial hypertension. Effect of long-term therapy with BPS is not well defined. This study assesses influence of long-term therapy with BPS on the survival of patients with precapillary pulmonary hypertension. Studied group consisted of 25 patients with precapillary PH (18 F, 7M, aged 34 +/- 13,9 years). Sixteen patients were diagnosed with primary PH, 3 pts had PH associated with connective tissue disease, 5 pts developed PH in course of congenital systemic to pulmonary shunt, and 1 patient suffered from inoperable chronic thromboembolic PH. At time of diagnosis 15 pts presented exercise impairment of WHO class II and 10 pts were in functional class III. All studied subjects had complete hemodynamic assessment of right heart and obtained values were used for estimation of hypothetic survival using prognostic equation proposed by D'Alonzo et al. On follow-up period patients received BPS in the highest tolerated dose (80-480 mg daily). During a follow-up period (mean: 22 months) 7 patients died. Cumulative survival rate BPS group was significantly higher in BPS group comparing to hypothetical survival at 6 months (96% (95% CI: 88-104%) vs 73% (95% CI: 67-78%), p = 0.02) and 12 months (94% (95% CI: 84-104%) vs 65% (58-71%), p = 0.01), respectively. At 18 and 24 months differences between BPS virtual and hypothetical survival were not statistically significant. There was no correlation between survival and maximal achieved dose of BPS. These results suggest, that BPS improves prognosis of patients with precapillary PH during 12 months after initiation of therapy. Later effect of BPS seems to decrease, requiring changing or intensification of therapy.

[Pulmonary thrombendarterectomy in a patient with chronic thromboembolic pulmonary hypertension (CTEPH) and chronic renal failure due to diabetic nephropathy--case report].

A case of 63-years old man suffering from CTEPH and chronic renal failure due to diabetic nephropathy is presented. First diagnosis of pulmonary hypertension was made at the beginning of 2000. Then the secondary anticoagulant prophylaxis were introduced. Despite such treatment there was no improvement and level of pulmonary hypertension increased. Finally, the pulmonary thrombectomy was considered because of proximal location of thromboembolic obstruction in pulmonary artery. Before surgery, the hemodialysis was started. Pulmonary thrombendarterectomy along with right coronary artery bypass grafting were performed in November 2001. The procedure was conducted successfully. The patient's condition improved and pulmonary pressure dropped substantially. During follow-up anticoagulant prophylaxis and hemodialysis are continued. It might be conducted that pulmonary thrombendarterectomy can be successfully performed also in patients with complex coexisting conditions.

[Scimitar syndrome--case report].

Scimitar syndrome is a rare congenital anomaly. This syndrome is characterized by partial or complete anomalous pulmonary venous drainage of the right lung to the inferior vena cava. There is a characteristic abnormal radiographic shadow which descends along the right cardiac border (scimitar sign). We examined 71-year old woman with severe pulmonary hypertension due to a large shunt between pulmonary veins and right atrium. Other cause of pulmonary hypertension is atrial septum defect. Our patient required permanent pacemaker implantation for tachy-brady syndrome.

[Diagnostic difficulties in primary mesothelioma].

A 54-year-old woman with a history of fatigue and shortness of breath was found to have a pericardial effusion and mild mediastinal lymphadenopathy. Video-assisted pericardioscopy revealed thickened pericardium studded with multiple nodules. Histologically the tumor was diagnosed as papillary adenocarcinoma. The site of the primary tumor could not be identified. As lung cancer is one of the most frequent causes of pericardial metastases the patient was treated with cisplatin and vinblastin. Following 5 courses of chemotherapy--given over a 4 month period--the amount of pericardial effusion and pericardial thickness did not change. The material from pericardial biopsy was reexamined and positive immunostaining for calretinine was found. The final diagnosis was primary pericardial mesothelioma of epithelioid type. Palliative radiotherapy of mediastinum was planned but the patient deteriorated and died due to disease progression with venous thrombosis and superior vena cava syndrome. The case illustrates the difficulties in establishing diagnosis of primary pericardial mesothelioma which is a rare tumor with poor prognosis.

[Autoimmune thyroid diseases in patients with primary pulmonary hypertension].

UNLABELLED: Abnormal metabolism due to thyroid disorders could cause the additional significant right ventricular (RV) overload in patients with primary pulmonary hypertension (PPH). The purpose of this study was the prospective determination of autoimmune thyroid status in PPH patients. MATERIAL: 45 patients (33 women and 12 men, mean age 38 years+/-13) with moderate and severe PPH (mean pulmonary artery pressure 61 mmHg+/-18 mmHg). PPH was diagnosed when other reason of pulmonary hypertension had been excluded especially thromboembolic, venous and hypoxemic. METHODS: Titer of antibodies to thyroglobulin and thyroid peroxidase were measured. Thyroid gland dysfunction was determined by biochemical measurements of thyrotropin and free thyroxine; thyroid ultrasonographic examination was also performed. The prevalence of thyroid autoantibodies is estimated at 13% in general population. RESULTS. In 14 patients (31%) increased titer of thyroid antibodies was found in our group. Hyperthyroidism was recognized in 2 patients and in 3 cases we diagnosed hypothyroidism with high antibodies level requiring treatment. Ultrasonographic abnormalities were revealed in 21 patients (nodular changes--11 patients, fibrosis--3 patients, chronic inflammation symptoms--7). Ultrasonographic abnormalities were present in all patients with detectable antithyroid antibodies. We haven't confirmed more frequent prevalence of hormonal disorders in patient treated with prostacyclin's analogues. CONCLUSION: The prevalence of autoimmune thyroid diseases is about 3 times higher in PPH patients than in general population. The treatment of patients with clinically evident hyper- or hypothyroidism is necessary. The monitoring of clinically silent disorders seems to be recommended especially prior to lung transplantation qualification.

[Mycobacterium kansasii infection in chronic thromboembolic pulmonary hypertension (CTEPH), report of two cases].

Mycobacterium kansasii infection leads to significant morbidity both in immunocompetent and immunocompromised patients. 7 subtypes of M. Kansasii were identified so far. Subtypes 1 and 2 are known to be pathogenic to humans, subtypes 3-7 are commonly isolated from the environment and rarely cause disease. In the present study we report on two cases of chronic thromboembolic pulmonary hypertension (CTEPH) complicated by M. kansasii infection. Disease was recognized according to ATS criteria. Resolution of lesions was observed in both patients in the course of antituberculous treatment. These are to our knowledge the first recognized cases of M. Kansasii infection in CTEPH. Chronic hypoxemia with impaired lung metabolism could be responsible for susceptibility to infection with nonpathogenic subtype 4 of M. Kansasii.

Detectable serum cardiac troponin T as a marker of poor prognosis among patients with chronic precapillary pulmonary hypertension.

BACKGROUND: Right ventricular failure is a leading cause of death in patients with chronic pulmonary hypertension (PH). We checked whether detection of cardiac troponin T (cTnT), a specific marker of myocyte injury, could be useful in prognostic stratification of those patients. METHODS AND RESULTS: Initial evaluation of 56 clinically stable patients (age 41+/-15 years) with pulmonary arterial (51 patients) or inoperable chronic thromboembolic (5 patients) PH (mean pulmonary arterial pressure 60+/-18 mm Hg) included cTnT test, allowing detection of its serum levels > or =0.01 ng/mL [cTnT(+)]. cTnT was detectable in 8 of 56 (14%) patients (mean+/-SD, 0.034+/-0.022; range, 0.010 to 0.077 ng/mL). Despite similar pulmonary hemodynamics, they had higher heart rate (92+/-15 versus 76+/-14 bpm, P=0.004), lower mixed venous oxygen saturation (50+/-10% versus 57+/-9%, P=0.04), and higher serum N-terminal pro-B-type natriuretic peptide (4528+/-3170 versus 2054+/-2168 pg/mL, P=0.03) and walked less during the 6-minute walk test (298+/-132 versus 396+/-101 m, P=0.02). Cumulative survival estimated by Kaplan-Meier curves was significantly worse at 24 months in cTnT(+) compared with cTnT(-) (29% versus 81%, respectively, log-rank test P=0.001). Multivariate analysis revealed cTnT status (hazard ratio, 4.89; 95% CI, 1.18 to 20.29; P=0.03), 6-minute walk test (hazard ratio, 0.93 for each 10 m; P=0.01), and pulmonary vascular resistance (hazard ratio, 1.13; P=0.01) as independent markers of mortality. All 3 cTnT(+) patients who survived the follow-up period converted to cTnT(-) during treatment. CONCLUSIONS: Detectable cTnT is a so-far ignored independent marker of increased mortality risk in patients with chronic precapillary PH, supporting the role of progressive myocyte injury in the vicious circle leading to hemodynamic destabilization.

Right heart thrombi in pulmonary embolism: results from the International Cooperative Pulmonary Embolism Registry.

OBJECTIVES: This study was designed to investigate the prevalence and prognostic significance of right heart thrombi (RHTh) in pulmonary embolism. BACKGROUND: Most reports about patients with RHTh are small case series. We analyzed data referring to RHTh among 2,454 consecutive pulmonary embolism patients enrolled in the International Cooperative Pulmonary Embolism Registry. METHODS: Of the 2,454 patients, 1,113 had results available from baseline echocardiography. We compared the 42 patients with RHTh versus 1,071 without RHTh. RESULTS: Patients with RHTh had shorter duration of symptoms (2.2 +/- 2.9 days vs. 4.3 +/- 6.0 days, p = 0.013), lower systolic blood pressure (BP) (116.0 +/- 28.8 vs. 125.7 +/- 25.0 mm Hg, p = 0.008), and more frequent right ventricular hypokinesis (64% vs. 40%, p = 0.002) and congestive heart failure (26% vs. 13%, p = 0.024); but they had similar age (62.9 vs. 62.5 years), arterial oxygen pressure (71.3 +/- 26.0 vs. 69.5 +/- 30.5 mm Hg), and prevalence of cancer (14% vs. 19%). The overall mortality rate at 14 days and at three months was higher in patients with RHTh (21% vs. 11%, p = 0.032, and 29% vs. 16%, p = 0.036). The difference in early mortality was observed almost entirely within the subgroup of patients treated with heparin alone (23.5% vs. 8%, p = 0.02), despite similar clinical severity at presentation (systolic BP 122.2 +/- 24.2 vs. 127.8 +/- 24.1 mm Hg, hypotension in 5.9% vs. 3.4% patients). CONCLUSIONS: Among patients with acute pulmonary embolism, RHTh is usually found in those more hemodynamically compromised but is also a marker of worse prognosis in initially apparently stable patients treated with heparin alone.

Effects of the oral endothelin-receptor antagonist bosentan on echocardiographic and doppler measures in patients with pulmonary arterial hypertension.

OBJECTIVES: The purpose of this study was to investigate the effects of bosentan (125 or 250 mg twice daily) on echocardiographic and Doppler variables in 85 patients with World Health Organization class III or IV pulmonary arterial hypertension (PAH). BACKGROUND: Bosentan, an orally active dual endothelin-receptor antagonist, improves symptoms, exercise capacity, and hemodynamics in patients with PAH. METHODS: Patients had primary pulmonary hypertension (84%) or PAH associated with connective tissue disease. Of these, 29 patients received placebo and 56 received bosentan (1:2 randomization). Six-minute walk tests and echocardiograms were performed at baseline and after 16 weeks of treatment. RESULTS: Baseline characteristics were similar in the placebo and bosentan groups, and echocardiographic and Doppler findings were consistent with marked abnormalities of right ventricular (RV) and left ventricular (LV) structure and function that were due to PAH. The treatment effect on 6-min walking distance was 37 m in favor of bosentan (p = 0.036). Treatment effects of bosentan compared with placebo on other parameters were as follows: Doppler-derived cardiac index = +0.4 l/min/m(2) (p = 0.007), LV early diastolic filling velocity = +10.5 cm/s (p = 0.003), LV end-diastolic area = +4.2 cm(2) (p = 0.003), LV systolic eccentricity index = -0.12 (p = 0.047), RV end-systolic area = -2.3 cm(2) (p = 0.057), RV:LV diastolic areas ratio = -0.64 (p = 0.007), Doppler RV index = -0.06 (p = 0.03), and percentage of patients with an improvement in pericardial effusion score = 17% (p = 0.05). CONCLUSIONS: Bosentan improves RV systolic function and LV early diastolic filling and leads to a decrease in RV dilation and an increase in LV size in patients with PAH.

Myoglobin stratifies short-term risk in acute major pulmonary embolism.

BACKGROUND: Concentrations of cardiac troponins can be elevated in acute pulmonary embolism (APE) indicating myocardial injury. Although concentration of myoglobin (MYO) increases after myocardial damage, even before detectable rise of cardiac troponin levels occurs, MYO was not evaluated in APE. Therefore, we assessed prevalence and prognostic significance of myoglobin in major APE. METHODS: We studied 46 patients (30 women, aged 61.9+/-17.8 years) with major APE defined with right ventricular dilatation. On admission serum myoglobin, and cardiac troponin T (cTnT) were measured. Serum MYO concentrations >58 ng/ml for women, and >72 ng/ml for men were considered abnormal. CTnT>0.01 ng/ml was regarded to indicate myocardial injury. RESULTS: MYO levels exceeding sex specific norms were found in 21/46 (45.7%) of patients, while detectable cTnT was found in 24/46 (52.1%) of patients. Seven patients died during hospitalization. Elevated MYO significantly predicted in-hospital mortality (OR 25, 95% CI 1.3-474.2), while increased cTnT concentration did not affect the survival. Among clinical and echocardiographic variables only older age indicated worse prognosis (OR 1.6, 95% CI 1.06-2.41). CONCLUSIONS: Myoglobin levels are elevated in serum on admission in almost half of patients with major APE. Elevated myoglobin level, marker of myocardial injury, is a powerful predictor of increased risk of fatal outcome in major pulmonary embolism.

Cardiac troponin T monitoring identifies high-risk group of normotensive patients with acute pulmonary embolism.

STUDY OBJECTIVES: Indications for thrombolysis in normotensive patients with pulmonary embolism (PE), based on the presence of right ventricular (RV) overload during transthoracic echocardiography (TTE), are controversial. We checked whether the monitoring of cardiac troponin T (cTnT) might help in risk stratification by detecting patients with RV myocardial injury. PATIENTS AND DESIGN: We studied 64 normotensive patients (30 women and 34 men) with a mean (+/- SD) age of 61.3 +/- 17 years and PE, who had undergone TTE for the assessment of RV overload. Plasma cTnT levels were measured quantitatively (detection limit, > 0.01 ng/mL) at hospital admission, and subsequently three times at 6-h intervals. Heparin therapy alone was used in 87.5% of patients, while 12.5% of patients received thrombolysis. RESULTS: cTnT was detected in 50% of patients. All eight in-hospital deaths occurred in the troponin-positive group, however, in one case the results of the first three assays had been negative. Elevated plasma cTnT increased the risk of PE-related death (odds ratio [OR], 21; 95% confidence interval [CI], 1.2 to 389). Increased age and elevated tricuspid regurgitant jet velocity, but not RV diameter/left ventricle diameter ratio, influenced the hospital mortality rate. Increased cTnT level was the only parameter predicting 15 in-hospital clinical adverse events (ie, death, thrombolysis, cardiopulmonary resuscitation, and IV use of catecholamine agents) [OR, 24.1; 95% CI, 2.9 to 200]. CONCLUSIONS: Patients with PE and elevated cTnT levels detected during repetitive assays are at a significant risk of a complicated clinical course and fatal outcome.

Atrial septostomy for severe primary pulmonary hypertension - report on two cases.

Atrial septostomy (AS) emerges as a potential therapeutic option in severe primary pulmonary hypertension (PH). AS isa transluminal intervention consisting of perforation of interatrial septum and balloon dilatation. During the procedure an atrial septal defect is created to a diameter permitting right-to-left shunt with the aim of correcting abnormal preload of both ventricles, leading to hemodynamic and functional consequences. We present two patients characterised by severe right ventricular failure. The second patient with rapid clinical deterioration required ,,rescue" rather than elective AS. Despite similar, small sizes of balloons (8 and 6 mm, respectively) used during both procedures, elective AS resulted in a significant and persistent hemodynamic (CI increased from 2.0 to 2.3 1/min/m(2)) and functional improvement while ,,rescue" AS despite short term improvement resulted in an uncontrolled systemic hypoxemia and did not prevent death 28 days after the procedure. Although AS is an invasive and palliative method, it offers persistent functional improvement in patients with primary PH. In view of poor prognosis and limited therapeutic options in Poland, elective AS should be considered as a potentially valuable intervention in patients with primary PH in our country.

Factors determining long-term maintenance of sinus rhythm after cardioversion of persistent atrial fibrillation.

BACKGROUND: Long-term maintenance of sinus rhythm (SR) after successful cardioversion (CV) of persistent atrial fibrillation (AF) carries a low risk of stroke and may avoid the risks associated with anticoagulation. AIM: To determine the clinical and echocardiographic predictors of maintaining SR during one-year follow-up. METHODS: The initial study group consisted of 205 patients with persistent AF of whom 104 (33 females, 71 males, mean age 60.4+/-7.4 years) were randomised to SR restoration and maintenance. The results of transthoracic echocardiography, obtained before CV, were compared between patients who remained in SR and those in whom AF recurred during a one-year follow-up period, using the linear and logistic regression analysis. RESULTS: SR was present in 63.5% of patients at the end of the follow-up period. Of several analysed echocardiographic parameters, an increased left atrial area (<28 cm(2)) (p<0.02; RR 1.72, OR 1.09-2.71) and an increase in the fractional shortening of the left ventricle (range 25-40%, p<0.05, RR 1.2, OR 1.01-1.44) were significantly associated with SR maintenance during a 12-month follow-up period. CONCLUSIONS: Left atrial area and left ventricular fractional shortening are the independent predictors of the maintenance of SR after successful CV in patients with persistent AF.

Rhythm control versus rate control in patients with persistent atrial fibrillation. Results of the HOT CAFE Polish Study.

BACKGROUND: Patients with atrial fibrillation (AF) can be managed either by maintaining sinus rhythm using antiarrhythmic drugs and/or electrical cardioversion, or by leaving patients in AF and controlling ventricular rate without attempts to restore sinus rhythm. Which of these two strategies is superior, has not yet been definitively established. AIM: HOT CAFE Polish Study (How To Treat Chronic Atrial Fibrillation) was designed to evaluate in a randomised, multicentre and prospective manner the risks and advantages of two therapeutical strategies - rate control or rhythm control, in patients with persistent AF. METHODS: The study group consisted of 205 patients (71 females and 134 males; mean age 60.8+/-11.2 years) with a mean time of AF duration of 273.7+/-112.4 days; 101 patients were randomly assigned to rate control (Group I) whereas 104 patients were randomised to sinus rhythm (SR) restoration by DC cardioversion (CV) and subsequent antiarrhythmic drug treatment (Group II). At the end of follow-up (12 months) SR was present in 75% of patients. RESULTS: The incidence of hospital admissions was higher in group II in comparison to group I (12% vs 74%; p<0.001). Mortality was similar in both groups (1.0% versus 2.9%, NS). In both groups a significant improvement of heart failure symptoms was observed during the first 2 months (p<0.02 and p<0.001). In group II exercise tolerability measured by maximal workload during treadmill test significantly improved compared with baseline (5.2+/-5.1 vs 7.6+/-3.3 MET; p<0.0001). In patients in whom SR was restored, the left ventricular function improved and an increase in the shortening fraction was observed (29+/-7% vs 31+/-7%; p<0.01). No thromboembolic complications were observed in patients left with AF. Three patients from group II suffered ischaemic stroke; in two cases stroke was associated with CV whereas in the third patient - with late AF recurrence. CONCLUSIONS: The HOT CAFE Polish Study did not reveal significant differences in mortality between the two treatment strategies in patients with persistent AF. Although patients with SR had better improvement in some haemodynamical parameters, the hospitalisation rate was higher and the incidence of stroke was not reduced compared with the rate control group.

[Pulmonary thromboembolism as a late complication of mitochondrial myopathy (Kearns-Sayer syndrome ].

A case of pulmonary thromboembolism with transient pulmonary hypertension of a rare cause is presented. In 24-year-old woman myasthenia was recognised on the ground of ptosis and fixation of eyes muscles from the 14th year of age. The treatment with mestinon was ineffective. Before planned thymectomy serious disturbances of heart rhythm and conduction were confirmed. Stimulator was implanted and thymectomy was done. No improvement of neurological state was observed despite the treatment with mestinone and prednisone. When she was 30 years old disease of lung appeared with fever, cough and parenchymal and pleural lesions of right lung. Antibiotic therapy was ineffective. CT scan and US examination revealed large thrombus inside the right auricle connected with stimulator electrodes. Embolisation of right pulmonary arteria was confirmed also. Treatment with heparin was ineffective and thrombectomy was performed. Exact neurological examination stated that the patient had no typical symptoms of myasthenia and that symptoms related with eyes and heart could be result of mitochondrial myopathy. Diagnosis was confirmed by EMG examination and muscle biopsy.
