Renin-Angiotensin System Blockade is Associated with Exercise Capacity, Sympathetic Activity and Endothelial Function in Patients with Chronic Kidney Disease.

Kidney & blood pressure research

Jeong JH, Sprick JD, DaCosta D, Quyyumi AA, Park J.
PMID: 34758473
Kidney Blood Press Res. 2021 Nov 10; doi: 10.1159/000520760. Epub 2021 Nov 10.

BACKGROUND: Chronic kidney disease (CKD) patients have exercise intolerance and exaggerated blood pressure reactivity during exercise that are mediated by sympathetic nervous system (SNS) overactivation and decreased nitric oxide (NO) bioavailability. Activation of the renin-angiotensin system (RAS) increases SNS...

Cardiovascular disease risk and pathophysiology in South Asians: can longitudinal multi-omics shed light?.

Cardiovascular disease (CVD) is the leading cause of mortality in South Asia, with rapidly increasing prevalence of hypertension, type 2 diabetes (T2DM) and hyperlipidemia over the last two decades. Atherosclerotic CVD (ASCVD) affects South Asians earlier in life and...

Highly elevated polygenic risk scores are better predictors of myocardial infarction risk early in life than later.

Genome medicine

Isgut M, Sun J, Quyyumi AA, Gibson G.
PMID: 33509272
Genome Med. 2021 Jan 28;13(1):13. doi: 10.1186/s13073-021-00828-8.

BACKGROUND: Several polygenic risk scores (PRS) have been developed for cardiovascular risk prediction, but the additive value of including PRS together with conventional risk factors for risk prediction is questionable. This study assesses the clinical utility of including four...

Neighborhood characteristics and ideal cardiovascular health among Black adults: results from the Morehouse-Emory Cardiovascular (MECA) Center for Health Equity.

PURPOSE: Neighborhood environment is increasingly recognized as an important determinant of cardiovascular health (CVH) among Black adults. Most research to date has focused on negative aspects of the neighborhood environment, with little attention being paid to the specific positive...

Association between race and maladaptive concentric left ventricular hypertrophy in American-style football athletes.

British journal of sports medicine

Br J Sports Med. 2021 Aug 13; doi: 10.1136/bjsports-2021-104333. Epub 2021 Aug 13.

OBJECTIVES: American-style football (ASF) athletes are at risk for the development of concentric left ventricular hypertrophy (C-LVH), an established cardiovascular risk factor in the general population. We sought to address whether black race is associated with acquired C-LVH in...

Racial Disparities in Adverse Cardiovascular Outcomes After a Myocardial Infarction in Young or Middle-Aged Patients.

Background Black patients tend to develop coronary artery disease at a younger age than other groups. Previous data on racial disparities in outcomes of myocardial infarction (MI) have been inconsistent and limited to older populations. Our objective was to...
