A role for the renin-angiotensin-aldosterone-system in Severe Acute Respiratory Syndrome-Coronavirus-2 infection and in the development of COronaVIrus Disease-19 disease has generated remarkable concerns among physicians and patients. Even though a suggestive pathophysiological link between renin-angiotensin-aldosterone-system and the virus has been proposed, its pathogenic role remains very difficult to be defined. Although COronaVIrus Disease-19 targets preferentially older people with high prevalence of hypertension and extensive use of renin-angiotensin-aldosterone-system inhibitors, an independent role for hypertension and its therapies is not defined. In this article, we scrutinize evidence from the most representative available studies in which the potential role of renin-angiotensin system inhibitors, specifically angiotensin-converting enzyme inhibitors and angiotensin receptor blockers, was evaluated in the COronaVIrus Disease-19 disease course, with regard to severity of the disease and mortality. We conclude that at this time, the overall available evidence fails to support a pathogenetic speaks against any harmful role for of renin-angiotensin-aldosterone-system inhibitors in COronaVIrus Disease-19. Consequently, we conclude that treatment with renin-angiotensin-aldosterone-system inhibitors should not be discontinued and, therefore, these therapies should not be interrupted. • The SARS-Cov2 utilizes the angiotensin-converting enzyme 2 to enter cells. • Renin angiotensin system inhibitors, increase angiotensin-converting enzyme II levels. • Therefore, these most common anti-hypertensive drugs might influence Covid-19. • Extensive data that has recently become available recently do not support this hypothesis. • We recommend that treatment with renin angiotensin system inhibitors should not be discontinued in Covid-19 patients.

Background Diabetes Mellitus (DM) is an important factor of adverse cardiovascular events in acute ST-segment elevation myocardial infarction (STEMI) patients. Renin-angiotensin-aldosterone system (RAAS) inhibitors is associated with improved clinical outcomes, however, there are limited data comparing the effectiveness of two different RAAS inhibitors in STEMI patients with DM undergoing percutaneous coronary intervention (PCI) with drug-eluting stents (DES). Methods A total of 3811 eligible STEMI patients with DM were enrolled in Korea Acute Myocardial Infarction Registry (KAMIR). They were stratified into two groups: Angiotensin converting enzyme inhibitors (ACEI) group (n = 2691) and angiotensin receptor blockers (ARB) group (n = 1120). To adjust baseline confounding factors, we performed propensity score matching (PSM) analysis and evaluated individual and composite major clinical outcomes between the two groups up to 2 years. Results After PSM, a total of 1049 well-matched pairs were generated. Baseline clinical, angiographic and procedural characteristics were well-balanced between the two groups. The incidence of death, recurrent myocardial infarction (MI), revascularization and major adverse cardiac events (MACE) were not significantly different between the two groups up to 2 years, Conclusion In the present study, ACEI and ARB showed comparable effectiveness and safety on individual and composite clinical outcomes in STEMI patients with DM who underwent successful PCI with DES at least up to 2 years.
