Hypertension Paid Clinical Trials in Alabama

Cardiovascular diseases (CVDs) are the number one cause of death in America and most of the post-industrial world. Hypertension is a leading risk factor for CVDs including stroke, myocardial infarction, and heart failure. Black Americans suffer from the highest rates of hypertension of any racial/ethnic group in America, among the highest in the world. There are also well-documented racial disparities in vascular dysfunction (e.g., endothelial dysfunction, arterial stiffening). Thus, racial disparities in hypertension and vascular dysfunction exacerbate the burden of CVDs, with Black Americans being 30% more likely to die from CVD than any other race in the US. It is established that mitochondrial dysfunction contributes to vascular dysfunction. However, there is a knowledge gap regarding whether targeting mitochondrial dysfunction attenuates oxidative stress, vascular dysfunction, and CVD risk among Black adults at heightened CVD risk. Thus, the investigators will conduct an 8-week trial with the mitochondrial antioxidant MitoQ in middle-aged and older Black and non-Black adults. Our overarching hypothesis is that mitochondrial dysfunction contributes to heightened oxidative stress, vascular dysfunction, and higher BP in Black adults; and that MitoQ will attenuate these racial differences. Importantly, the investigators will also assess social determinants of health (e.g., income, neighborhood disadvantage, discrimination) and health behaviors (e.g., diet, physical activity) and uncover their role in oxidative stress, vascular function, and BP Regarding methodology, the investigators will perform blood draws, vascular testing, preceding and following an 8-week, 20mg daily consumption of MitoQ and placebo. The investigators will also measure urine biomarkers of kidney function and blood pressure in adults (45-75 years old). Read Less
