- Do You Know The Symptoms Of Heart Attack?
According to a new US study, the heart attack treatment is the most effective when it is given within an hour after the symptoms occur, but many people with heart disease do not know the symptoms of a heart attack.
Kathleen Dracup and colleagues at the University of California, San Francisco, School of Nursing studied 3,522 patients, who had previously suffered a heart attack or had undergone a procedure, such as angioplasty, for heart disease, in the United States, Australia and New Zealand.
The researchers found that 44 percent of them had poor knowledge about the symptoms of heart attack. They said, the lack of knowledge about the range of heart attack symptoms as measured in the study, is shocking.
According to researchers, those who suffer a heart attack have a better chance of surviving if treatment begins within one hour, but most patients are admitted to the hospital 2-1/2 hours to three hours after symptoms begin.
The study concluded that shorter hospital stays and a move to outpatient treatment have decreased the amount of patient’s knowledge about heart attack symptoms, which include nausea and pain in the jaw, chest or left arm.
- Coffee Drinking May Reduce The Risk Of Heart Disease

A study published in Annals of Internal Medicine, coffee drinking may reduce a person’s risk of dying from heart disease. The study conducted by a team of researchers led by Esther Lopez Garcia of Universidad Autonoma de Madrid, in Spain, indicated that long term coffee consumption may have some beneficial effects rather than the detrimental ones as believed earlier.
The study was based on study conducted on 84214 women and 41736 men over a 20 year period from 1986-2004. The subjects of the study filled out questionnaires on their coffee drinking habits as well as diet, smoking and general health.
The study found that women who consumed 2-3 cups of regular caffeinated coffee a day had a 25% lower risk of heart disease and an 18% lower risk of death by causes other than cancer or heart disease, as compared to non coffee drinkers. Men who drank 3 cups of coffee a day did not show any higher or lower risk. Earlier reports had a mixed bag about the health benefits and side effects of coffee drinking.
Surprisingly, caffeine was not the link as people who drank decaffeinated coffee also showed a lower death risk than those who didn’t drink coffee at all. The study could find no link between coffee drinking and cancer either.
- Toned Milk Keeps Heart Healthy
Toned milk or fat free milk helps to keep the heart healthy and protected from strokes or other heart diseases — stated a a new study published in the American Journal of Clinical Nutrition.
Scientists from several universities in the United States and Norway measured the kidney function of more than 5,000 older adults in the age group of 45 to 84. They reached the conclusion that a low or no intake can indicate poor kidney function and an extremely high risk for cardiovascular disease. People consuming more low-fat milk and milk products had lower ACR, or healthier kidney function.
The researchers found that adults who drink at least one serving of low-fat milk or milk products have 37 per cent lower odds of poor kidney function linked to heart disease than those who do not drink regularly.
The study also suggested that the nine essential nutrients, including protein, vitamin A, vitamin D, magnesium, potassium and calcium found in milk may contribute to milk's potential heart health benefits. The U.S. Dietary Guidelines for Americans recommend drinking three glasses of low fat or fat free milk each day.
- Air Pollution Can Be Dangerous For Your Heart Too!
Yes, air pollution can be dangerous for your heart too! That’s what a new study states. According to the study, microscopic particles in polluted air can adversely affect your heart. These particles can interrupt the progress of electrical signals which are conducted by the heart.
Harvard University researchers conducted the study on 48 patients from Boston. All the patients had coronary artery disease. To examine the electrocardiograms of the participants, researchers used 24-hour Holter monitors. ST- segment depression is an indicator for inadequate blood flow to the heart or inflamed heart muscles.
Usually we found the polluted air in traffic jams. It contains very high pollutant level. A particular pollutant with this level called as PM 2.5 and black carbon, a marker for traffic predicted ST-segment depression, generally we found in heavy vehicular traffic exhaust along with sulphur dioxide.
The study’s senior author Diane R Gold said, “Effects were greatest within the first month after hospitalization, and for patients who were hospitalized for a heart attack or had diabetes’s.”
The researchers concluded that road traffic can trigger heart attacks and the particulate air pollution can raise the risk of heart attack.
- Heart Patients Should Avoid Traffic Pollution

Heart patients should avoid traffic pollution, stated a recent US study. According to the study, traffic pollution can hinder heart’s ability to conduct electrical signals. The researchers at Harvard University said that people who have serious coronary artery disease could have problems from the tiny particles emitted from air pollution as well as the black carbon from exhaust fumes that could cause ST segment depression. This usually indicates an inadequate supply of oxygen and blood flow to the heart.
Published in Circulation: Journal of the American Heart Association, the study was based on the electrocardiograms of 48 patients who had been hospitalized for heart attack, unstable angina or deteriorating symptoms of coronary heart disease over the period of a year. The subjects wore special monitors that intermittently checked for ST-segment depression during the study period.

- Doctors Can Hear The Heart Attack Risks Using Stethoscope!
According to a new US study, doctors can hear the heart attack risks using stethoscope. Published in the May 10 issue of The Lancet, the study articulated that certain sound in the main artery supplying blood to the brain could indicate an increased risk of heart attack and death from heart disease and stroke.
The study stated that the sound - called a carotid bruit (pronounced brew-ee) - is caused by turbulent blood flow due to buildup of fatty deposits in one of the two arteries that carry blood to the front and middle part of the brain. It is usually regarded as a possible indicator of increased risk of stroke.
After analysis of 22 studies, the researchers at Walter Reed Army Medical Center in Washington, D.C. concluded that people with carotid bruits are more than twice as likely to have heart attacks or to die of cardiovascular disease. Pickett and colleagues analyzed data from 17,295 patients in 22 studies from the U.S., Canada, the U.K., the Netherlands and Switzerland and did a follow-up for four years. They concluded that "the presence of a carotid bruit should heighten clinician concern for coronary heart disease.”
Christopher Pickett from the Walter Reed Army Medical Center, stated, “Our study has shown that the presence of a carotid bruit significantly increased the likelihood of cardiovascular death or heart attack.''
- Obese children show early signs of heart diseases

Obese children show early signs of heart diseases, articulated a study published in the Winter 2007 issue of the Journal of Cardiometabolic Syndrome. The study by researchers at the Washington University School of Medicine revealed that such kids are at greater risk for complications such as diabetes, high blood pressure and heart disease, because obesity increases total blood volume, which leads to extra stress on the heart.
Angela Sharkey, M.D., associate professor of paediatrics at Washington University School of Medicine and a paediatric cardiologist at St. Louis Children's Hospital, said, "Based on this study, these subtle markers can help us predict who could be at risk for heart disease and heart attacks."
Sharkey and Steven M. Lorch, M.D., a former fellow at the School of Medicine now at University of Texas Health Science Center at Houston, studied data from 168 children ages 10 to 18 who had been referred to them for cardiac ultrasound with symptoms including heart murmur, chest pain, acid reflux or high blood cholesterol.
