Estudo do efeito de estatinas e antiplaquetários na evolução do infarto agudo do miocárdio: uma abordagem metabolômica multiplataform

O infarto agudo do miocárdio (IAM) é a maior causa de mortalidade no mundo. A oclusão coronária determina a necrose completa de cardiomiócitos (células musculares cardíacas) durante as primeiras horas do IAM. Porém, mesmo após a perda de massa de miocárdio viável cessar, a região infartada po...

Role of ACE and ACE-2 in abrogated cardioprotective effect of ischemic preconditioning in ovariectomized rat heart

Abstract Ischemic heart disease is the leading cause of death in postmenopausal women. The activity of heart ACE increases whereas the activity of ACE-2 decreases after menopause. The present study was designed to investigate the role of ACE and ACE-2 in the abrogated cardioprotective effect of IPC in OV...

Quantification of DNA Damage in Different Tissues in Rats with Heart Failure

Arq. bras. cardiol; 114 (2), 2020
Abstract Background: Chronic heart failure (CHF) is a complex syndrome which comprises structural and functional alterations in the heart in maintaining the adequate blood demand to all tissues. Few investigations sought to evaluate oxidative DNA damage in CHF. Objective: To quantify the DNA damage usi...

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...

Vascular endothelial growth factor association with angiopoietin 1 promotes improvement in ventricular function after ischemic cardiomyopathy induced in mini pigs

Acta cir. bras; 33 (4), 2018
Abstract Purpose: To investigate the safety and clinical, hemodynamic and tissue improvement ability in mini pigs undergoing cell and gene therapy for the treatment of acute myocardial infarction. Methods: Thirty-two mini pigs Br1 lineage, 12 months old, undergoing induction of acute myocardial infarct...

Practical Implications of Myocardial Viability Studies

Arq. bras. cardiol; 110 (3), 2018
Abstract Many non-invasive methods, such as imaging tests, have been developed aiming to add a contribution to existing studies in estimating patients' prognosis after myocardial injury. This prognosis is proportional to myocardial viability, which is evaluated in coronary artery disease and left ventric...

Importância do diabetes mellitus na estratificação do risco de doença arterial coronária e risco cardiovascular global

O diabetes mellitus é uma doença epidêmica. Os adultos portadores de diabetes têm taxas de doenças cardiovasculares duas a três vezes maiores do que aquelas observadas em adultos não diabéticos. O reconhecimento de que o diabetes é uma doença heterogênea em relação ao risco cardiovascular fo...

The effect of periodontal therapy on neopterin and vascular cell adhesion molecule-1 levels in chronic periodontitis patients with and without acute myocardial infarction: a case-control study

J. appl. oral sci; 26 (), 2018
Abstract The presence of neopterin in gingival crevicular fluid (GCF) is a marker for local and acute immune activation, and the presence of vascular cell adhesion molecule (VCAM-1) in GCF is accepted as a marker for chronic vascular inflammation. Objectives This study aimed to evaluate effects of perio...

Rupture of the myocardium in autopsied MI hearts

Summary Although myocardial rupture occurs in only 2% to 4% of cases of acute myocardial infarction (AMI), there is a high mortality rate due to acute cardiogenic shock. We present the anatomopathological findings of three cases of myocardial rupture in autopsied hearts in the last 30 years, with a diagn...
