Impact of chronic obstructive pulmonary disease on short-term outcome in patients with ST-elevation myocardial infarction during COVID-19 pandemic: insights from the international multicenter ISACS-STEMI registry.

Background: Chronic obstructive pulmonary disease (COPD) is projected to become the third cause of mortality worldwide. COPD shares several pathophysiological mechanisms with cardiovascular disease, especially atherosclerosis. However, no definite answers are available on the prognostic role of COPD in the setting of ST elevation myocardial infarction (STEMI), especially during COVID-19 pandemic, among patients undergoing primary angioplasty, that is therefore the aim of the current study.

Orthostatic changes in blood pressure and survival in elderly cardiopaths.

Objective: The objective of this study was to analyze the association between orthostatic changes in blood pressure and mortality in elderly cardiopath patients.

Methods: A cohort of 455 elderly cardiopath patients, monitored at a referral outpatient cardiology clinic in Pernambuco, Brazil, from October 2015 to July 2018. The exposure groups were formed according to their orthostatic changes in blood pressure following the requirements of the Brazilian Guidelines for Hypertension.

Circulating interleukin-17A in patients with acute and chronic coronary syndromes.

Introduction: Interleukin 17 (IL-17) is produced by Th17 and other cells. It is debatable whether IL-17 is atherogenic or atheroprotective. The role of this interleukin in the development and progression of coronary artery disease is unknown.

Renin-angiotensin system inhibitors and mortality among diabetic patients with STEMI undergoing mechanical reperfusion during the COVID-19 pandemic.

Background: During the coronavirus disease 2019 (COVID-19) pandemic, concerns have been arisen on the use of renin-angiotensin system inhibitors (RASI) due to the potentially increased expression of Angiotensin-converting-enzyme (ACE)2 and patient's susceptibility to SARS-CoV2 infection. Diabetes mellitus have been recognized favoring the coronavirus infection with consequent increase mortality in COVID-19. No data have been so far reported in diabetic patients suffering from ST-elevation myocardial infarction (STEMI), a very high-risk population deserving of RASI treatment.

Triggering receptor expressed on myeloid cells-1 as pediatric sepsis biomarker.

Objective: Triggering receptor expressed on myeloid cells-1 concentration can be used as a predictive, diagnostic, and prognostic marker in patients with sepsis. The objective of this study was to determine the validity of triggering receptor expressed on myeloid cells-1 levels as a biomarker of sepsis in pediatric patients.

Methods: This was an integrative literature review.

Down regulation of VDR gene expression in metabolic syndrome and atherosclerosis' patients: Cause or consequence?

Background: Metabolic syndrome (MS) features a set of clinical manifestations with an increased risk of atherosclerosis development. Vitamin D (VD) pathway influences upon clinical features in MS as well in the formation of atherosclerotic plaque. VD acts through the vitamin D receptor (VDR), regulating the transcription of several genes involved in the immune response, growth and homeostasis.

A systematic review on durability and structural valve deterioration in TAVR and surgical AVR.

Mechanical valves and bioprosthetic heart valves are widely used for aortic valve replacement (AVR). Mechanical valves are associated with risk of bleeding because of oral anticoagulation, while the durability and structural valve deterioration (SVD) represent the main limitation of the bioprosthetic heart valves. The implantation of bioprosthetic heart valves is increasing precipitously due aging population, and the widespread use of transcatheter aortic valve replacement (TAVR).

Caveolin-1 (CAV-1) up regulation in metabolic syndrome: all roads leading to the same end.

Metabolic syndrome (MS) is a set of clinical conditions such as insulin resistance, hyperglycemia, systemic arterial hypertension (SAH), dyslipidemia, obesity and high abdominal circumference. Some of these clinical characteristics have been associated with caveolin-1, a caveolae structural protein, responsible for insulin activation, storage and degradation of cholesterol, and so on. Herein we assessed CAV-1 mRNA levels in MS patients comparing to healthy controls (HC) and according patients' clinical features.
