Angiotensin News and Research

RSS

Angiotensin is an oligopeptide in the blood that causes vasoconstriction, increased blood pressure, and release of aldosterone from the adrenal cortex. It is a powerful dipsogen. It is derived from the precursor molecule angiotensinogen, a serum globulin produced in the liver. It plays an important role in the renin-angiotensin system.

The BEAUTIFUL study: Ivabradine and the reduction of cardiovascular events

The results of the much awaited BEAUTIFUL (morBidity-mortality EvAlUaTion of the If inhibitor ivabradine in patients with CAD and left ventricULar dysfunction) trial have shown that coronary artery disease (CAD) patients with left ventricular dysfunction (LVD) and a heart rate more than 70 bpm have a significantly higher risk of cardiovascular death and other cardiovascular events and in these patients (heart rate above 70 bpm) treatment with ivabradine further reduces the risk of the most important coronary events such as fatal and non-fatal myocardial infarction and coronary revascularisation by one third, even when these patients are already receiving optimal therapy.

Global study shows Telmisartan reduces outcome of cardiovascular death, heart attack or stroke

An international study led by Canadian researchers has found that telmisartan, a medication used to lower blood pressure, reduced the outcome of cardiovascular death, heart attack or stroke in people who are unable to tolerate a widely available and effective standard treatment.

Researchers devise means to create blood by discovering earliest form of human blood stem cells

Johns Hopkins researchers have discovered the earliest form of human blood stem cells and deciphered the mechanism by which these embryonic stem cells replicate and grow. They also found a surprising biological marker that pinpoints these stem cells, which serve as the progenitors for red blood cells and lymphocytes.

Pregnancy increases risk of acute myocardial infarction

Although acute myocardial infarction (AMI) is rare in women of child-bearing age, pregnancy can increase a woman's risk of heart attack 3- to 4-fold, according to a study published in the July 15, 2008, issue of the Journal of the American College of Cardiology.

Mitochondrial dysfunction and redox signaling in atrial tachyarrhythmia

Researchers at the University Hospital of Magdeburg (Germany) have discovered that atrial tachycardia is associated with mitochondrial dysfunction and oxidative stress followed by the activation of the NF-kB signalling pathway with induction of NF-kB target gene expression in atrial tissue.

Women are treated less frequently than men with statins, aspirin and beta-blockers

Women and men experience a similar prevalence of adverse drug reactions in the treatment of coronary artery disease; however, women are significantly less likely than their male counterparts to be treated with statins, aspirin, and beta-blockers according to a new study by researchers at Rush University Medical Center.
