[Myocardial ischemia with stable angina pectoris: clinico-ergometric evaluation after the use of diltiazem].

PURPOSE: To evaluate the efficacy of diltiazem versus placebo in patients with stable angina. METHODS: Eight-seven angina pectoris patients, mean age of 57 +/- 9, 82 white and 79 male were evaluated in a randomized, double-blind trial of two groups of patients diltiazem and placebo, 3 to 4 tablets a day (diltiazem 180 to 240 mg daily). The patients were evaluated after laboratory tests and clinical-ergometric examinations. A coronary arteriography was performed on study entry. RESULTS: The average of anginal attacks, number of weekly sublingual nitrate, heart rate, systolic and diastolic pressure at rest and at the end of diltiazem period were significantly lower (p < 0.05) regarding same periods on placebo. The percentage of depression for ST-segment was lower for diltiazem when compared with placebo (p < 0.05) and the percentage of patients that reach higher stages in the ergometric test was significantly better for diltiazem. Heart rate and systolic plus diastolic pressures after exercise did not differ in both groups. CONCLUSION: Diltiazem reduced the clinical and electrocardiographical aspects and raises the effort tolerance during the ergometric test in patients with stable angina.

[Hypocalcemia causing heart failure].

A 39-year-old female patient with refractory heart failure has been studied. On February, 1982 she was submitted to right lobar thyroidectomy for remotion of the left thyroid lobe. Following the surgery, she had signs of hypocalcemia and the diagnosis of secondary hypoparathyroidism and heart failure had been made. Seven months after she had acute pulmonary edema, cardiomegaly III (cardiothoracic index = 0.58) with predominant left atrial and left ventricular hypertrophy, which were confirmed by echocardiogram (ECO). The ECO also demonstrated low contractility of the left ventricle. The QT interval was increased on the electrocardiogram (QTc = 0.50 s), the calcium was 5.0 mg/dl with calciuria of 28 mg/day; phosphatemia was 4.8 mg/dl and phosphaturia of 214 mg/day. The level of thyroid hormones (T3 and T4) were in the normal ranges despite the TSH was increased in the beginning of the disease. She was first treated with digitalis, diuretic and vasodilator drugs, thyroid hormone and oral calcium. She had progressive hemodynamic improvement when higher doses of calcium were given with D3 vitamin. The most significant result of this treatment was reduction of the heart size that come back to normal. At the present time patient is treated with thyroid hormone, calcium and D3 vitamin only.

[Acute myocardial infarct in a patient with dextrorotation].

A 79-year-old woman developed myocardial infarction associated with acute pulmonary edema. The electrocardiogram recorded QRS complex of QS type in V1 with upper ST extending from V3R to V6R. The polarity of the P wave in bipolar leads was positive, so compatible with dextrorotation complicated by myocardial infarction. The dextrorotation was confirmed with chest roentgenogram and echocardiogram.

[Familial complete atrioventricular block in patients with hypertrophic cardiomyopathy].

The association of spontaneous complete heart block and hypertrophic cardiomyopathy is rare. We have studied three patients of the same family, two brothers and one nephew, ages 19-41 years, with hypertrophic cardiomyopathy confirmed by hemodynamic and angiographic studies. All patients were treated with permanent cardiac pacemaker implant. They are asymptomatic, aging 33 to 55 years, with follow-up of 157 to 176 months after the onset of the heart block.

[Significance of prolonged PR interval in patients with His bundle branch block, bifascicular type].

PURPOSE: Evaluation of the prolonged PR interval and its predictive value for trifascicular block in individuals with bifascicular His bundle branch block. PATIENTS AND METHODS: 55 patients, 36 male and 19 female aged 57 + 15.8 years with bifascicular bundle branch block type have been studied. 11 cases had complete left bundle branch block and 44 cases had complete right bundle branch block with left anterior and superior division block. His bundle electrogram and atrial stimulation were performed in all patients. The atrial stimulation rate originating the Wenckebach phenomenon (SP) of the A-V conduction, and the A-H and H-V intervals were compared with the PR interval of the surface electrocardiogram. Patients were divided into three groups according to the PR interval: group I, Pr less than 200 ms, group II, PR between 190-280 ms and group III, PR greater than or equal to 280 ms. RESULTS: There was not linear correlation between the PR interval and WP in the three groups. There was a weak linear ascending correlation between the PR and A-H intervals in groups I and II (r + 0.59 and + + 0.43, respectively) and there was a descending correlation in the group III (r. - 0.64, P less than 0.05). In relation to the H-V interval there was not linear correlation with the PR interval in groups I and II, but there was a good ascending linear correlation in the group III (r 0.84, P less than 0.01). The incidence of prolonged A-H and H-V intervals increased as the PR interval was larger. CONCLUSION: The prolonged PR interval with bifascicular bundle branch block means, in the majority of cases, diffuse damage of the conduction system involving the A-V node and the infranodal region; starting from 280 ms, the delayed PR interval suggests involvement predominantly below the A-V node: to a higher PR interval corresponds a higher H-V interval and also, to a relatively shortest A-H interval.

[Apical lesion of the left ventricle in clinical evolution of chronic Chagas cardiopathy].

PURPOSE: Study of clinical evolutionary aspect in patients with apical lesion of chronic Chagas' heart disease diagnosed by left cineventriculography. PATIENTS AND METHODS: 55 patients, 32 female, aged 22 to 69 years with epidemiologic data and positive serological tests, all presenting cardiovascular symptoms, 20 in cardiac failure (10 with left ventricular failure and 10 in congestive heart failure). Heart size was normal in 35 patients and 20 showed cardiomegaly on chest X-ray examinations (slight in 8, moderate in 6 and marked in 6), EKG showed premature beats in all patients and conduction defects in 38 instances with a predominance of right bundle branch block associated with left anterior divisional block in 19 cases. The following morphological aspects of the apical lesions were observed: mammillary--23 (41.82%); digital--18 (32.73%) and semilunar--14 (25.45%). In 8 cases (14.54%) intraventricular thrombi were detected and in 10 (18.18%) there were associated dyskinetic areas. RESULTS: The clinical course of 36 patients (65%) has been followed in the out patient department for 35 to 192 (97.83) months. Seven patients (12.73%) did not return for consultation after having been studied for 22 to 56 (42.83) months, and 12 (22%) died after a follow-up period of 19 to 176 (68.58) months. Detection of 17 thromboembolic episodes occurred in the 14 (25%) patients, 9 pulmonary encephalic and 1 peripheric, very frequent in patients with cardiac failure (11/14-78%). Cardiac pacemakers were implanted in 18 cases due to complete A-V block in 11, to sinus node dysfunction in 6, and to sinus arrest in 1. Among the survivors 29 (80%) maintained a normal heart size. The most frequent cause of death (12) was heart failure in 8, followed by cerebrovascular attacks in 3 and malignancy in 1. The estimated survival in 192 months was of 75.8%, males (74.5%) and females (76.6%). A presence of heart failure however was a limiting factor, with estimates of 96.8% survival in patients without cardiac decompensation, as compared to 36.5% in cases with heart failure. CONCLUSION: The apical lesion is an additional factor of mortality in Chagas' heart disease after the development of congestive heart failure.

[Assessment of third-degree congenital atrioventricular block by ergometric tests].

PURPOSE: To analyse the use of the exercise testing as the method of initial evaluation, following a prognostic indicative of patients with congenital complete heart block. METHODS: Five patients were analysed (3 men and 2 woman) with ages between 7 and 34 years (mean = 22.8). The patients were submitted to a treadmill exercise testing using the Bruce protocol 1 and symptom limited. RESULTS: In all patients the atrial frequency increased from a median of 74.40 bpm in the basal to 155.20 bpm in the maximum effort; the atrial chronotropism was a little below that calculated based on the age of the patients. The median of the ventricular frequency in the maximum effort was 94.80 bpm, very different from that foreseen and showing a deficit of ventricular chronotropism. The median consumption of oxygen was 35.68ml0(2)/Kg/min. In one patients (20%) there was not any change in the ventricular frequency with the effort, in 3 (60%) complex ventricular arrhythmia arise during the effort and in one (20%) a definitive ventricular pacemaker was implanted. CONCLUSIONS: The exercise testing is a simple method of initial evaluation, providing information as chronotropism, functional capacity and the presence of arrhythmias, that can be very useful in the evaluation of prognostic. The presence of complex ventricular arrhythmias during the exercise is indicative of a more regular follow-up.

[Evaluation of syncope in patients with chronic Chagas heart disease].

PURPOSE: To evaluate causes of syncope in patients with Chagas' disease and intraventricular conduction disturbances. METHODS: Nine patients have been studied, being seven males. Average of 49 years. The studied consisted of His Bundle electrogram, determination of Wenckebach period (WP), sinus node recovery time (SNRT), atrial stability and programmed ventricular stimulation (PVS). RESULTS: Monomorphic ventricular tachycardia (VT) was induced in five patients (55.5%), WP depression was observed in three cases, H-V interval prolongation occurred in three cases and the SNRT was normal in hall patients. In one case the electrophysiological study was completely normal. Among five patients with induced VT, with a mean follow-up period of seven months, one died suddenly, three became asymptomatic with antiarrhythmic drugs and one went on a non pharmacological therapy. In the other four patients with a mean follow-up period of 21 months, three are asymptomatic and one presents occasional dizziness (patient with a normal study). Among the patients with VT four presented recurrent syncope while in the group of patients without VT (four patients) all had only one syncopal episode. CONCLUSION: Patients with intraventricular disturbances, Chagas' disease and syncope, VT may be responsible for the symptoms in approximately 44% of cases. The PVS must be considered as a routine in the investigation of these patients.

[Silent coronary artery-left ventricular fistula and acute myocardial ischemia].

A 65-year-old woman developed severe coronary insufficiency associated with papillary muscle dysfunction. She was submitted to cineangiocoronarography which ruled out obstructive coronary disease. Coronarography revealed a communication between the coronary arteries and the left ventricle, but a coronary arterial fistula was not seen. The possibility of this uncommon form of coronary drainage to the left ventricle, named silent fistula, being the cause of myocardial ischemia related to the coronary steal phenomenon is discussed.

[Evaluation of the PR intervals in normal and prolonged maximum limit with short QRS].

PURPOSE: Evaluation of the A-V node function by determining the Wenckebach period (WP) and atropine response in cases of normal PR interval, PR interval at maximum normal range and prolonged PR interval, all with short QRS. PATIENTS AND METHODS: 129 patients, 79 male and 50 female, aged 17 to 84 years (mean 59), asymptomatic or with complaints of palpitations, dizziness, presyncope or syncope has been studied. ECG showed supra-ventricular tachycardia, first degree A-V block or intermittent Mobitz I type A-V block and sick sinus syndrome. Preexcitation (WPW) syndrome and longitudinal A-V dissociation were excluded. Electrical transoesophageal atrial stimulation was performed in all patients for evaluating the PR interval and WP. Atropine test was performed in a group of 16 patients. Based on the values of the WP, patients were divided into three groups: group I, WP greater than or equal to 125 ppm (N = 88); group II, WP ranging 125-110 ppm (N = 16) and group III, WP less than or equal to 110 ppm (N = 25). RESULTS: There was a good decreasing lineal correlation between the PR interval and the WP only in the group III (r = 0.76, p less than 0.01). PR interval greater than 240 ms had greatest and significant incidence in the group III in relation to the other groups in which the number of WP post-atropine normalization was observed. CONCLUSION: There is a strong linear decreasing correlation between the PR interval of the ECG and the WP in individuals with WP less than or equal to 110 ppm. PR interval greatest than 0.24 ms corresponds better to WP below 110 ppm (mean 90 ppm) and the majority of these patients do not normalize the WP with the atropine. We suggest the term "first degree A-V block" for those cases with PR interval greater than 240 ms and "A-V depression" for the cases with PR interval shorter than 240 ms when recorded on the surface electrocardiogram and have been normalized with atropine.

[Thromboembolism in patients with apical lesion caused by chronic chagasic cardiopathy].

The thromboembolism in patients with apical lesion of the chronic Chagas' heart disease diagnosticated by left cineventriculography are present in this study. The series comprises 32 females and 23 males between the ages of 22 and 69 years, all presenting cardiovascular symptoms, 20 in cardiac failure (10 with left ventricular failure and 10 in congestive heart failure). Heart size was normal in 35 instances and 20 showed cardiomegaly on chest X-ray examinations (slight in 8, moderate in 6 and marked in 6). The following morphological aspects of the apical lesions were observed: mammillary-23 (41.82%); digital-18 (32.73%) and semilunar-14 (25.45%). In 8 cases (14.54%) intraventricular thrombi were detected and 10 these were associated with discinetic areas. Seventeen episodes of thromboembolism occurred in 14 (24.45%) patients including 7 to the brain, 9 to the lung and 1 to the iliac right artery, mostly in patients with heart failure. Eight were women and 6 were men, varying between 30 and 62 years of age, the morphological aspects of the apical lesion were semilunar in 8 and mammillary in 6. Cardiac pacemakers were implanted in 8 cases due to complete A-V block in 6, to sinus node disfunction in 1, and to sinus arrest in 1. In 4 cases (28.57%) intraventricular thrombi were detected, in 3 occasioned thromboembolism to the brain. Thrombo-embolic phenomena occurred in the 11 nonsurvivors. The most frequent cause of death was heart failure in 8 followed by cerebro-vascular attacks in 3, after a follow-up period of 19 to 176 months.(ABSTRACT TRUNCATED AT 250 WORDS)

[Significance and prognosis of ventricular extrasystole induced by exertion in patients with arterial hypertension with a normal electrocardiogram].

We studied 13 patients with systemic arterial hypertension and normal electrocardiograms so as to evaluate the significance and prognosis of frequent and complex ventricular premature beats (VPB) induced by exercise testing. After a period of 9 to 33 months of follow-up (mean = 17.6 months), we repeated the exercise testing with the same protocol in all cases. In nine patients (69.2%), the arrhythmia disappeared during exercise, two increased the number of VPB and two others reduced the number of the arrhythmia. Complications, such as sustained ventricular tachycardia, were not seen in any case. The appearance of frequent and complex VPB with stress testing does not seem enhance the risk of sudden death or episodes of spontaneous ventricular tachycardia in patients with arterial hypertension but without electrocardiographic signs of cardiac hypertrophy.

[Apical left ventricular involvement in chronic Chagas' cardiopathy: clinical and ventriculographic aspects].

The present study comprises 62 patients with Chronic Chagas' Heart Disease. In addition to clinical examination, serologic, roentgenologic, hemodynamic, electrocardiographic, left cineventriculographic and cinecoronariographic studies were performed, with subsequent evaluation apical left ventricule. Thirty two patients were women and 30 were men, varying between 21 and 64 years of age, all with positive serological tests, all with cardiovascular symptoms, 26 with myocardial failure (11 with left ventricular failure and 15 with congestive heart failure), heart size was normal on X-ray in 37 patients with cardiomegaly in 25 (slight in 10; moderate in 8 and accentuate in 7). The electrocardiogram revealed in 41 instance of conduction defects. The left ventriculogram showed an apical lesion in 52 patients (83.87%) with: localized hypokicinetic in 4 (6.45%), diffuse hypokicinetic in 6 (9.68%) and, apical lesion in 48 (77.42%). The shaped apical lesion as a nipple in 17 (27.42%), as finger in 17 (27.42%), and half-moon in 14 (22.18%). The apical lesion was observed in 20 of 26 patients with myocardial failure (76.92%). In 9 patients was associated with others aneurysms. In 3 patients apical thrombus was detected.

[Diabetic cardiac dysautonomia. Clinical and pharmacologic evaluation].

Thirty-two insulin-dependent (type I) diabetic patients were studied to detect cardiovascular autonomic nervous system involvement. Half percent (16 cases) were men. Their ages ranged from 6 to 64 years (29.03 years). The average time of diagnosed diabetes was 6.5 years. The group was submitted to several clinical (respiratory, arrhythmia, Valsalva, isometric, orthostatic) and pharmacological tests (propranolol and atropine). The physiological responses were measured as heart beat frequency and blood pressure. Results were analyzed by various statistical methods. Evaluation through a diabetic complication scale showed that ten (31.25%) were uncomplicated), 14 (43.75%) at grade 1, four (12.50%) at grade 2, two (6.25%) at grade 3 and two (6.25%) at grade 4. This scale only correlated to the term of diabetes (p less than 0.01). Results from the autonomic test battery indicated that 12 (37.50%) had isolated parasympathetic damage, five (15.62%) sympathetic lesions, and two (6.25%) had mixed type involvement. We observed, as to cardiovascular autonomic involvement, 13 (40.62%) had no involvement and 19 (59.38%) had some degree of damage; in the latter group, 15 (46.78%) had early lesions and four (12.50%) definite.

[Surgical treatment of high-risk valvar endocarditis].

The authors have studied the immediate and long term outcome of surgical treatment of acute phase infective endocarditis in a group of 33 high risk patients with valvular heart disease. The age varied from 2 to 68 years, 18 patients were male and 22 were of the white race. The aortic valve was the most frequently involved (18/54.5%), followed by mitral valve (13/39.3%), and tricuspid valve (2/6.0%). Twenty-four patients (72.7%) were in functional class III and seven (21.0%) in functional class IV. The noninvasive studies in those patients revealed 13 cases (39.4%) with normal cardiac size. The EKG was abnormal in 27 cases (81.8%) mostly with left atrial and ventricular hypertrophy. The echocardiogram revealed the presence of vegetations in 27 patients (81.8%) and the blood cultures were positive in 24 cases (72.7%). All patients were treated with antibiotics. The pathologic analysis revealed the presence of vegetations in 94% and structural alterations in 16.5%. Twenty-one patients had heart valve replacement with mechanical prosthesis (63.6%), 11 (33.3%) had bioprosthesis and one had tricuspid excision without replacement (3.0%). The hospital mortality was 12% and the late mortality 3%. Three deaths occurred in patients who had prolonged clinical treatment (more than 35 days) and one patient died of severe fungal endocarditis. The follow-up of the remaining 26 patients varied from 1 to 596 weeks (mean 183) demonstrating important clinical improvement and a normally functioning valve prosthesis. All patients remained in functional class I or II. The analysis of our data indicates that surgical treatment is the best option for high risk endocarditis and should be undertaken earlier in all patients in this group.

[Prevalence of tricuspid and aortic valve prolapse in patients with mitral valve prolapse].

Two-dimensional echocardiograms were performed in 30 patients with mitral valve prolapse (15 females and 15 males, with an average of 33.3). The main objective was to observe the prevalence of involvement of tricuspid and aortic valves. Tricuspid valve prolapse was observed in 43.3% with anterior and septal involvement in 92.3% and posterior involvement in 15.3%. The incidence of aortic prolapse was 10% with involvement of both right coronary and non-coronary leaflets. All patients with aortic valve prolapse showed involvement of both mitral leaflets and at least two tricuspid leaflets. It is concluded that involvement of other valves such as tricuspid (43.3) and aortic (10%) is a common finding in patients with mitral valve prolapse.
