Objective: In the four SMILE (Survival of Myocardial Infarction Long-Term Evaluation) studies, early administration of zofenopril in acute myocardial infarction (AMI) showed beneficial effects as compared to placebo and other angiotensin converting enzyme inhibitors (ACEIs). This study investigated whether the concomitant administration of the dihydropyridine calcium channel-blocker amlodipine may improve zofenopril efficacy to prevent cardiovascular events in post-AMI patients. Methods: This was a post-hoc analysis of pooled individual patient data from the four large randomized SMILE studies. The primary endpoint was the 1-year combined occurrence of death or hospitalization for cardiovascular causes. Results: In total, 3488 patients were considered, 303 (8.7%) treated with concomitant amlodipine. Baseline systolic blood pressure and prevalence of metabolic syndrome were higher in amlodipine treated patients. The 1-year occurrence of major cardiovascular outcomes was significantly reduced in patients receiving concomitant treatment with amlodipine (hazard ratio, HR = 0.66; and 95% confidence interval, CI = 0.44–0.98; p =.039). After accounting for treatment with amlodipine, the risk of cardiovascular events was significantly reduced with zofenopril compared to placebo (HR = 0.78; 95% CI = 0.63–0.97; p =.026]. Among ACEI-treated patients, the zofenopril plus amlodipine combination reduced the risk of cardiovascular events by 38%, compared to the combination of other ACEIs plus amlodipine [HR = 0.76; 95% CI = 0.61–0.94); p =.013). The prognostic benefit of concomitant treatment with zofenopril plus amlodipine was independent from blood pressure lowering. Conclusions: Zofenopril had a positive impact on prognosis in post-AMI patients, compared to other ACEIs. Concomitant administration of amlodipine may help to reduce the risk of cardiovascular events at 1 year.

To evaluate the prevalence of arterial hypertension (AH) in heart transplant recipients, and its influence on the risk of adverse events, as the efficacy and safety of antihypertension medications (AHM). Material and methods. To the study, were consequently included all heart transplant recipients operated in the Shumakov Centre during the years 2013 to 2016 and survived 90 days after orthotopic heart transplantation. Results. Totally, 353 recipients included, with AH or AHM intake in anamnesis in 62 (17,6%). Within 90 days post surgery, AH that demanded for medication therapy was found in 151 (42,8%) patients. In posttransplant AH patients there were the following specific parameters in preoperational period: higher body mass index - 25,7±4,1 vs 24,9±4,4 (р=0,026), blood creatinine concentration - 100,6±62,6 vs 68,8±4,8 (р<0,001), donor heart posterior wall thickness - 11,9±0,8 vs 11,3±0,7 (р=0,034), creatinine concentration in 3 month after operation - 131,7±101,6 vs 94,1±46,5 (p<0,001). There was relation revealed, of AH development risk with anamnesis of AH and renal failure, as a necessity for renal replacement therapy within 30 days post surgery and episodes of acute antibody-mediated reaction on transplant. In the recipients taking angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers (ACEi/ARB) before operation, the survival rate free from adverse events was better than in those taking calcium channel blockers (CCB) (plog-rank=0,042). Conclusion. The results of the study point on high prevalence of AH in heart recipients. Presence of AH in anamnesis, renal failure, episodes of humoral, but not cellular, reaction to the transplant, and donor heart hypertrophy do significantly increase the probability of AH development after transplantation. Comparison revealed significant benefit of ACEi/ ARB versus CCB as antihypertension medications in either monotherapy or in combination with diuretics.
