Viruses, Vaccines, and Vigilance

Overview of Beta Blockers for Systolic Heart Failure: Which Beta Blocker Should Be Used?

Beta blockers with intrinsic sympathomimetic activity, such as acebutolol (Sectral, ESP Pharma) and pindolol (Visken, Novartis), should be avoided, because this property may increase mortality. As for beta blockers without intrinsic sympathomimetic activity, it seems prudent to use those agents that do improve survival. These include both the nonselective beta blocker carvedilol and the cardioselective […]

Overview of Beta Blockers for Systolic Heart Failure: Reduced Mortality with Beta Blockade As Shown in Major Trials

Since 1996, major mortality benefits for patients with systolic dysfunction have been demonstrated in several large trials involving bucindolol, carvedilol, and the long-acting form of metoprolol canadian succinate (XL, AstraZeneca).

Overview of Beta Blockers for Systolic Heart Failure: Brief Overview of Beta Blockers

In 1948, Ahlquist demonstrated that adrenergic receptors can be divided into two types: alpha and beta. A decade later, a specific inhibitor of the beta class of adrenergic receptors was identified. There are at least three subtypes of beta receptors: Beta 1 receptors are found primarily in heart myocytes. Blockade of beta 1 receptors slows […]

Overview of Beta Blockers for Systolic Heart Failure

It is estimated that more than 4.5 million Americans have this condition. Each year, more than 500,000 new cases of heart failure are diagnosed in the U.S. Data from […]

Body Mass Index Relates: DISCUSSION

The mean BMI (30.2 ± 5.6kg/m2) of our study population placed black and white male military veterans with PTSD in the obese category, with 84.1% of them overweight, obese or morbidly obese. This value of 84.1% exceeded the current national finding of 64.5% by about 20%. White male PTSD veterans tended to be slightly more […]

Body Mass Index Relates: RESULTS

The mean age of the 252 male veterans was 55.8 ± 8.8 years (black, n=146, 54.9 ± 8.2 years and white, n=106, 56.9 ± 9.6 years; df=250, t=1.767, p=0.078). The youngest veteran was 23 years old and the oldest veteran was 85 years old.
