Incidence of Cardiac Arrest in Marathon Participants Increasing

cardiac arrest marathon
  Running has always been advocated as one of the best forms of exercise. However, more and more cases of race related cardiac arrests have been making news. A team of researchers from Massachusetts General Hospital tried to investigate whether participating in marathons and half-marathons is really associated with an increased risk of developing cardiac arrest. The results, which have been published in the New England Journal of Medicine, show that participating in marathons and half...

Consuming a diet rich in fish, vegetables, legumes and moderate amount of alcohol has been known to reduce the risk of cardiovascular events. A diet consisting of these components, called as the Mediterranean diet, has been advocated for a good heart health. However, it was noticed that  people of African American and Hispanic origin, residing in New York were unable o procure traditional Mediterranean diet.

New Genes Responsible for Influencing Blood Pressure Identified

    The International Consortium for Blood Pressure Genome-Wide Association Studies has in a new study, identified sixteen new gene regions which can influence blood pressure. Besides these new regions, the existence of twelve other gene regions responsible for influencing the blood pressure, which had been reported earlier, has also been confirmed. The study, which has been published in the September 11, 2011 issue of the journal “Nature and Nature Genetics”, will further aid our...

Pulsus Paradoxus

Normal person exhibit a 10 mmHg drop in systolic pressure during normal inspiration. A greater decline in systolic pressure accompanied by marked decrease in pulse amplitude during inspiration results in pulsus paradoxus. Thus it is an exaggeration of normal physiological response when additional pathological factors contribute to the drop in left ventricular stroke volume during inspiration. The paradox is that while cardiac auscultation with a stethoscope would reveal the central pulse, it...

Coronary Calcium a Better Predictor of Heart Attack and Stroke than C - reactive protein

coronary calcium deposit
  A new study, conducted to find people at higher risk of developing heart attack and stroke, has come to the conclusion that presence of calcium in the coronary arteries is a much better predictor of these conditions as compared to C- reactive protein in patients with a normal level of LDL. The study, published in the August 19, 2011 issue of “The Lancet”, was conducted on more than 2,000 people led by Michael J. Blaha, M.D. M.P.H, a cardiology fellow at the Johns Hopkins University School...
