ABSTRACT

Objective: To determine the clinical and epidemiological characteristics of patients with short-term mechanical circulatory support devices (MCSD) after myocardial infarction (MI) at a national referral hospital. Materials and methods: Descriptive, retrospective study of post-MI patients in whom short-term mechanical circulatory support devices were implanted from 2015 to 2020. Results: Nine mechanical support devices were implanted, in the same number of patients due to cardiogenic shock post MI. All patients were men with ST-elevation myocardial infarction (STEMI). Eight extracorporeal membrane oxygenation devices (ECMO) and one centrifugal flow pump (in LVAD configuration) were implanted. The median time of use of the devices was eight days. The most frequent complications were non-fatal bleeding (55.6%), acute kidney injury (44.4%) and sepsis (44.4%).In-hospital mortality was 55.6 %. Conclusions: The use of short term MCSD after myocardial infarction is still limited in our institution and its main representative is the ECMO post STEMI complicated by cardiogenic shock. Despite the use of these devices, in-hospital mortality is high.

ABSTRACT

Objective: To evaluate the epidemiological, clinical, surgical, pathological characteristics and outcomes in the follow-up of heart transplant recipients at the National Cardiovascular Institute during 2010-2020. Material and Methods: A retrospective descriptive study was performed by reviewing the medical records of patients undergoing heart transplantation at a national referral center, describing the clinical, surgical, laboratory, pathology characteristics and survival of patients up to 10 years of follow-up. Results: Eighty-six patients were transplanted in 10 years, the median age was 41 years (RIQ 28-56), being predominantly male (66.3%). The three leading causes of indication for heart transplantation were: dilated cardiomyopathy (48.9%), ischemic heart disease (17.4%), and myocarditis (6.9%). Total ischemia time was 160 minutes (RIQ 129.7-233.5). Survival at one, five, and ten years was 84.8%, 73.6%, and 65.7% respectively. The main cause of death was non-cardiac: infectious (39.1%) and of unknown origin (26%). Conclusions: The main etiology of heart failure in heart transplant recipients in Peru in recent years was nonischemic dilated cardiomyopathy. We observed that the survival rate was similar to that of international registries; however, the rate of mortality due to infectious causes and death of unknown origin is high, which poses a challenge in the management of post-transplant patients.
