Desafios na interpretação dos ensaios de troponina ultrassensível em terapia intensiva

RESUMO As troponinas cardíacas T e I são marcadores considerados altamente sensíveis e específicos para o diagnóstico de infarto agudo do miocárdio. Atualmente, com o advento dos ensaios ultrassensíveis, uma série de anormalidades não primariamente cardíacas pode se manifestar por meio da eleva...

Elevated High-Sensitivity Troponin I in the Stabilized Phase after an Acute Coronary Syndrome Predicts All-Cause and Cardiovascular Mortality in a Highly Admixed Population: A 7-Year Cohort

Arq. bras. cardiol; 112 (3), 2019
Abstract Background: High-sensitivity cardiac troponin I (hs-cTnI) has played an important role in the risk stratification of patients during the in-hospital phase of acute coronary syndrome (ACS), but few studies have determined its role as a long-term prognostic marker in the outpatient setting. Obje...

Injuria miocárdica postcirugía no cardiaca (MINS) en pacientes sometidos a cirugía vascular: artículo de revisión

Rev chil anest; 48 (5), 2019
Vascular surgery is considered high risk, due to the characteristics of patients and surgical procedures. Recently, the diagnosis of myocardial injury after non-cardiac surgery (MINS) was introduced to focus attention on the prognostic relevance of elevated ischemic troponin after non-cardiac surgery. In...

Alprostadil attenuates myocardial ischemia/reperfusion injury by promoting antioxidant activity and eNOS activation in rats

Acta cir. bras; 33 (12), 2018
Abstract Purpose: To investigate the effect of alprostadil on myocardial ischemia/reperfusion (I/R) in rats. Methods: Rats were subjected to myocardial ischemia for 30 min followed by 24h reperfusion. Alprostadil (4 or 8 μg/kg) was intravenously administered at the time of reperfusion and myocar...

Serial High-Sensitivity Troponin T in Post-Primary Angioplasty Exercise Test

Arq. bras. cardiol; 106 (4), 2016
Abstract Background: The kinetics of high-sensitivity troponin T (hscTnT) release should be studied in different situations, including functional tests with transient ischemic abnormalities. Objective: To evaluate the release of hscTnT by serial measurements after exercise testing (ET), and to correlat...
