Is delayed facilitated percutaneous coronary intervention better than immediate in reperfused myocardial infarction? Six months follow up findings.

BACKGROUND: There are several new strategies proposed to improve the outcome of patients with ST-elevation myocardial infarction (STEMI). One approach is the resurgent use of facilitated percutaneous coronary interventions (PCI). Until recently, deciding whether immediate PCI after combined treatment (facilitated PCI) is more appropriate than delayed PCI (short time) has not been investigated. The aim of this study, therefore, was to investigate the outcomes in patients initially successfully treated pharmacologically and immediate PCI < 2 hr, and in patients initially successfully treated with pharmacological therapy and with delayed PCI (12-72 h). METHODS: 451 reperfused STEMI patients, aged 18 to 75 years, class I-II Killip, with an acceptable echocardiographic window and admitted within 12 hs of the onset of symptoms were randomized into two groups. All patients had to have successful reperfusion, to receive the combination of a standard tirofiban infusion or abciximab plus half dose rtPA. Thereafter, patients were sub-grouped as follows:group 1 (immediate PCI) patients had PCI within 2 h; and group 2 (delayed PCI) patients in which PCI was performed after 12 hs and within 72 hs. RESULTS: The 225 reperfused (immediate-PCI) and 226 reperfused (delayed-PCI) patients (time from randomization to PCI 165 +/- 37 min in immediate PCI versus 45.1 +/- 20.2 h in delayed PCI group) showed similar results in ejection fraction, CK release and patency of the IRA. In addition, the delayed PCI group showed a significant reduction in ischemic events, restenosis and bleedings (P = 0.005, 0.01, 0.01 respectively) and significant reduced angiographic evidence of thrombus formation in the infarction-related artery (IRA) (p = 0.001). CONCLUSION: Our data suggest the safety and possible use of delayed facilitated PCI in patients with STEMI, and that delayed PCI in patients treated with combined lytic and IIb/IIIa inhibitors appears to be as effective and possibly superior (reduced ischemic events and repeat PCI) as immediate PCI. The patients in this study were successfully reperfused, with TIMI-3 flow and our data may not apply to patients with TIMI 0-2 flow. This strategy could allow transferring the reperfused patients and performing PCI after hours < 72 hours and not immediately, thereby reducing the number of urgent PCI and costs, obtaining similar results, but mostly causing less discomfort to the patient. Our results had to be interpreted with caution, because current guidelines do not recommend the combined therapy, but suggest further studies. The study was aimed to investigate the outcomes in patients initially successfully treated pharmacologically and immediate PCI < 2 h, and in patients initially successfully treated with pharmacological therapy and delayed PCI (12-72 h). All patients had to have successful reperfusion, to receive the combination of a standard abciximab or tirofiban infusion plus half dose rtPA. Similar results were observed in both groups. Delayed PCI group showed a significant lower incidence in restenosis (0.01), minor bleedings (0.005), ischemic events (0.01) and a reduced angiographic evidence of thrombus formation in IRA (0.001). Our data suggest the safety and possible use of delayed facilitated PCI in patients with STEMI. Our results had to be interpreted with caution, because current guidelines do not recommend the combined therapy, but suggest further studies.

Changes in brain natriuretic peptide levels and bioelectrical impedance measurements after treatment with high-dose furosemide and hypertonic saline solution versus high-dose furosemide alone in refractory congestive heart failure: a double-blind study.

OBJECTIVES: The aim of this study was to evaluate the effect of a new treatment for refractory congestive heart failure (CHF) on brain natriuretic peptide (BNP) plasma levels and hydration station. BACKGROUND: The study was aimed at evaluating the effects of the combination of high-dose furosemide and small-volume hypertonic saline solution (HSS) in refractory CHF patients. METHODS: A total of 94 patients (34 women/60 men) with refractory CHF (age 55 to 80 years) were enrolled. They had to have an ejection fraction <35%, serum creatinine <2 mg/dl, blood urea nitrogen <60 mg/dl, a reduced urinary volume, and a low natriuresis (<500 ml/24 h and <60 mEq/24 h, respectively). Patients were divided (double-blind) into two groups: group 1 (18 women/30 men) received an intravenous furosemide (500 to 1,000 mg) plus HSS twice a day in 30 min. Group 2 (16 women/30 men) received an intravenous bolus of furosemide (500 to 1,000 mg/twice a day) alone, for four to six days. At entry, body weight, blood pressure, heart rate, and laboratory parameters were checked during hospitalization; BNP levels were measured on admission, 6 and 30 days after discharge, while on admission and 6 days after, impedance plethysmography was performed. The HSS group received 120 mmol of Na intake versus 80 mmol in non-HSS group. Fluid intake of 1,000 was given to both groups. RESULTS: The groups were similar for clinical characteristics. A significant increase in daily diuresis and natriuresis was observed in HSS group, p < 0.05. The BNP values showed significant intragroup and intergroup differences, 6 and 30 days after treatment. The patients from the HSS group reached a better hydration state than the non-HSS group after six days. In addition, the HSS group showed a significant reduction in hospitalization time and readmission rate. CONCLUSIONS: Our data show that the HSS group reached dry weight more rapidly, a significantly faster reduction in BNP levels, shorter hospitalization stay, and lower incidence in readmissions in the 30-day study period.

Effects of canrenoate plus angiotensin-converting enzyme inhibitors versus angiotensin-converting enzyme inhibitors alone on systolic and diastolic function in patients with acute anterior myocardial infarction.

BACKGROUND: Aldosterone (ALDO) exerts profibrotic effects, acting via the mineralocorticoid receptors in cardiovascular tissues. Aldosterone antagonism in combination with angiotensin-converting enzyme inhibition may better protect against the untoward effects of ALDO than angiotensin-converting enzyme inhibition alone. METHODS: In a double-blind randomized study, the tolerability and efficacy of canrenoate (25 mg/d) plus captopril versus captopril alone were evaluated in 510 patients with an acute anterior myocardial infarction (MI), a serum creatinine concentration < 2.0 mg/dL, and a serum potassium level < 5.0 mmol/L. Three hundred forty-one patients received captopril and 25-mg canrenoate (group A). Group B (346 patients) received captopril and placebo. At baseline and at 10, 90, and 180 days after admission, Doppler echocardiography was performed. RESULTS: Clinical and demographic aspects were similar in both groups. In addition, baseline cardiac enzyme levels, left ventricular function, and incidence of surgical interventions and angioplasty were comparable. Overall, creatinine, blood urea, and serum potassium levels did not show significant differences between groups. However, in 18 patients in group A, increases in serum potassium levels to > 5.5 mEq/L and creatinine levels to > 2.0 mg/L after 10 days of treatment were observed. At 180 days, the mitral E-wave-A-wave ratio was higher (P = .0001) and left ventricular end-systolic volume was smaller (P = .0001) in patients treated with canrenoate than in those receiving placebo. No further side effects were observed during the study period. CONCLUSIONS: Our data suggest that the combination of captopril plus canrenoate is well tolerated after an acute MI and has beneficial effect on systolic and diastolic parameters and may decrease post-MI remodeling.

Immediate versus delayed facilitated percutaneous coronary intervention: a pilot study.

The study was aimed to investigate the outcomes in patients initially successfully treated pharmacologically and immediate PCI <2 hours, and in patients initially successfully treated with pharmacological therapy and delayed PCI (12-72 hours). All patients had to have successful reperfusion, to receive the combination of a standard abciximab infusion plus half dose rtPA. Similar results were observed in both groups. Delayed PCI group showed a favorable trend in restenosis and bleedings (ns) and a significant reduced angiographic evidence of thrombus formation in IRA. Our very preliminary data suggest the safety and possible use of delayed facilitated PCI in patients with STEMI. The studied patients have successful reperfusion and TIMI-3 flow and our data may not apply to patients with TIMI 0-2 flow.

Cardiovascular effects of I/D angiotensin-converting enzyme gene polymorphism in healthy subjects. Findings after follow-up of six years.

BACKGROUND: An increasing number of studies with conflicting results regarding the association between angiotensin-converting enzyme (ACE) gene deletion polymorphism and cardiovascular disease has recently been published. The present prospective long-term study was conducted to evaluate whether the DD genotype could also be associated with a higher prevalence of hypertension in healthy subjects over 6 years of follow-up. We also investigated the effects of the ACE-I/D genotypes on diastolic function by echocardiography in healthy subjects without any risk factors and any events after 6 years of follow-up. METHODS POPULATION: 684 healthy volunteers (aged 25-55 years) normotensive and free of cardiovascular diseases, with acceptable echocardiographic window were enrolled. All subjects had to have a normal electrocardiogram (ECG) and echocardiogram (ECHO) at entry. All subjects have undergone a complete physical examination, 12-lead ECG and ECHO; DNA analysis and serum cholesterol have been performed on venous blood samples. All subjects underwent a clinical evaluation each year for the 6-year duration of the study. In addition, 275 subjects without any risk factors underwent an ECHO every year of the follow-up, to check the influence of genotypes on myocardial diastolic performances. RESULTS: All 684 subjects completed 6 years of follow-up. We obtained 3 genetically distinct groups: I) the ACE-DD group (n = 225, 80 F/ 145 M, mean age 43.4 +/- 7.6 years) with 42 hypertensive subjects (18.3%), 5 heart failure (HF) subjects and 6 subjects with acute coronary syndromes (ACS). There was no association between family history, smoking habit, hypercholesterolaemia and events. 2) the ACE-ID group (n = 335, 116 F/2 19 M, mean age 43.6 +/- 7 years) with 16 hypertensive subjects (4.7%) and 3 subjects with ACS. 3) the ACE-II group (n = 124, 45 F/79 M, mean age 42.5 +/- 6.9 years) with 2 hypertensive subjects (1.6%) and I HF subject. The incidence of hypertension and cardiovascular events, was significantly higher in the ACE-DD (53 cases, 23%) than in the ACE-ID and ACE-II groups (20 and 3 cases, 5.9% and 2.4%, respectively), p = 0.0001. The higher incidence of hypertension was observed in the older age groups (36-45 and 46-55 years) with ACE-DD and ACE-ID genotypes. Moreover, ACE-DD significantly and early affected myocardial diastolic properties in the total group examined, also when stratified for age. There was a reduction of E/A ratio and it was more evident in subjects aged 36-45 and 46-55 years, p = 0.0001. CONCLUSION: Our data suggest that ACE-DD polymorphism is associated with a higher incidence of hypertension in baseline healthy subjects, irrespective of other risk factors, and appears to affect the diastolic function. These effects were apparent predominantly in the older age groups.

[Pharmacological treatment of depression after acute myocardial infarction].

Depressed mood and other depressive symptoms frequently appear after acute myocardial infarction and it is known how these patients have an increased risk for morbidity and mortality compared to patients without depression. Many risk factors promote the development of clinical depression in patients with recent myocardial infarction. Although a large number of studies underline the negative prognostic impact of depression on the infarcted patient, only rarely depressed patients are appropriately diagnosed and treated. Furthermore it should be borne in mind that the use of psychotropics in medically ill patients requires attention. These compounds, in fact, may interact with the disease causing several complications. In addition since the cardiologic patient is often treated with other drugs, the risk of clinically significant pharmacological interactions is obviously improved. It seems appropriate to give some considerations about therapy and management of the infarcted patient with depression.
