Cardiovascular Disease

Patients unaware of waist size heart disease risk

Mon Sep 19, 2005

LONDON (Reuters) - Patients, and even some doctors, are unaware that abdominal fat and waist circumference are important risk factors for heart disease which kills 17 million people worldwide each year.

An international survey released on Monday showed that only a minority of patients and about 60 percent of doctors know that a bigger waist size raises their odds of having a heart attack.

Heart Disease: Another Culprit to Watch

By Howard Lewine, M.D.

Monday, January 24, 2005;

Until recently, doctors primarily focused on lowering blood levels of LDL ("bad") cholesterol and raising HDL ("good") cholesterol to slow down the growth of the cholesterol-filled plaques that cause heart disease by impairing blood flow in the coronary arteries. The new CRP research does not change the importance of moving LDL and HDL cholesterol in the right directions. If anything, the target for LDL keeps moving down.

High blood-clot risk with obesity confirmed

NEW YORK (Reuters Health) - Obesity boosts the risk of venous thromboembolism -- the formation in veins of blood clots that can travel to the lungs -- and is a particularly strong risk factor among men and women under 40 years old, according to a new report.

Blood pressure lowering helpful after stroke

Tue Sep 6, 2005

By Anthony J. Brown, MD

NEW YORK (Reuters Health) - After people suffer a stroke, lowering their blood pressure can slow or even stop the progression of lesions in the brain, new research suggests. The areas of damage are called white matter hyperintensities, or WMHs, because they show up brightly on MRI, and they have been linked to the development of dementia and depression.

Women less likely to survive heart bypass surgery

By Amy Norton

NEW YORK (Reuters Health) - Women are nearly twice as likely as men to die from complications of heart bypass surgery, and their typically smaller body size may be one of the reasons, according to a study published Tuesday.

In a review of records for 15,440 patients who had undergone coronary artery bypass grafting (CABG), researchers found that 4.24 percent of women died during or immediately after surgery, versus 2.23 percent of men, a statistically significant difference.

Unsuspected diabetes common in heart patients

Mon Aug 22, 2005

NEW YORK (Reuters Health) - Diabetes often goes unrecognized -- and therefore untreated -- in people who suffer a heart attack or have severe coronary heart disease, according to new research.

Dr. Darcy Green Conaway told Reuters Health that "the majority of patients" who are seen in emergency rooms with a heart attack or heart-related chest pain "have impaired glucose metabolism," and this represents an opportunity for doctors to intervene. "Only once we recognize what we are missing can we then improve it."

High blood pressure linked to higher glaucoma risk

Mon Aug 15, 2005

By David Douglas

NEW YORK (Reuters Health) - The results of a study involving more that 27,000 people with glaucoma suggest that high blood pressure, also known as hypertension, is significantly more common in this group than in those who do not have hypertension, UK researchers report. They also found that treating hypertension with beta-blocker drugs, but not other types of antihypertensive drugs, lowered the risk of glaucoma.

Salt restriction improves blood pressure in blacks

By Will Boggs, MD Mon Aug 8, 2005

NEW YORK (Reuters Health) - Modest reductions in dietary salt can benefit black people with high blood pressure considerably, UK researchers report.

"This study...contributes to the growing and compelling evidence that salt reduction reduces blood pressure and thus will reduce cardiovascular risk," lead investigator Dr. Pauline A. Swift from St. George's Hospital Medical Center, London, told Reuters Health.

'Prehypertension' triples heart attack risk -study

Thu Aug 4, 2005

WASHINGTON (Reuters) - People whose blood pressure is slightly elevated -- a condition called prehypertension -- have triple the risk of a heart attack compared to those with healthy blood pressure, researchers said on Thursday.

The finding, published in the journal Stroke, supports a move by federal and academic heart experts last year that defines prehypertension as blood pressure between 120/80 and 139/89. High blood pressure starts at 140/90.
