April 25, 2007 Patients with HIV who are treated with protease inhibitors have an increased risk of heart attack, according to a study published in the New England Journal of Medicine. Combination antiretroviral therapy has had a dramatic effect in reducing illness and death associated with the HIV virus, however an earlier study showed that the risk of heart attacks increased by 17% with every year a patient spent on antiretroviral. It isn’t known, though, whether all antiretroviral drugs carry this risk. The assessment of the role of any specific drug is difficult because patients with HIV usually receive a combination of drugs, and often switch regimens because of the availability of newer substances, adverse events, or drug regimen failure. Previous studies have shown a relationship between the use of protease inhibitors, a class of antiretroviral drug, and cardiovascular disease, but there is little information on the risks associated with another class of antiretroviral therapy called nonnucleoside reverse-transcriptase inhibitors. In this study, more than 23,000 patients infected with the HIV virus were assessed to determine the incidence of heart attack and the association between heart attack and exposure to protease inhibitors or nonnucleoside reverse-transcriptase inhibitors. Confirming the earlier results, the researchers found the risk of having a heart attack increased by 16% per year of exposure to protease inhibitors alone, which is equal to twice the risk over five years. Not such effect was observed with nonnucleoside reverse-transcriptase inhibitors. It is thought that protease inhibitors raise the level of blood lipid, thereby increasing the risk of cardiovascular disease and heart attack. Patients treated with protease inhibitors should have their cholesterol and blood pressure levels monitored, and take steps to reduce their lifestyle-related risk factors. This includes maintaining a healthy weight, eating a low-fat diet rich in fruits in vegetables, and getting regular exercise. Reporting for Insidermedicine, I'm Dr. Susan Sharma.

(March 17, 2010 - Insidermedicine) From Atlanta - Being skinny does not reduce risk of sudden cardiac death, according to a report presented at the American College of Cardiology meeting. Researchers studied over 1200 patients with a history of at least one heart attack, finding that non-obese heart failure patients were at 76% increased risk of sudden cardiac death when compared to obese heart failure patients. From South Africa - According to a report published in the American Journal of Respiratory and Critical Care Medicine, a new tuberculosis booster shot may improve resistance in adults. Researchers developed the Aeras-402 vaccine by weakening TB virus to the point that it could no longer replicate, inserting antigens that would then stimulate the immune system. The vaccine was proven safe in humans and shown to stimulate the immune system to further protect against TB. And finally, From Egypt - According to a report published International Journal of Food Safety, Nutrition and Public Health, obese pregnant women or those who have been occasionally exposed to smoke during pregnancy may put their child at increased risk of future health problems. Researchers studied the umbilical cords of 65 babies, finding that mothers who were obese during pregnancy, or who smoked passively during pregnancy, reduced the amount of oxygen that reached their unborn child.

(March 15, 2010 - Insidermedicine) From Atlanta - According to a report presented at the American College of Cardiology meeting, vitamin D supplementation may reduce risk of heart disease. Researchers studied nearly 10,000 patients with low vitamin D levels, finding that 47% of those who raised their vitamin D levels after one year had a lower risk of heart disease. From Ohio - Newborns who receive oxygen supplementation with nasal CPAP may be at increased risk of developing nasal ventilation complications, according to a report published in the Archives of Otolaryngology–Head & Neck Surgery. Researchers studied 100 newborns who underwent either nasal CPAP or oxygen supplementation with cannula. They found that 13% of those who underwent nasal CPAP developed nasal complications, while those who received the nasal cannula developed no such problems. And finally, back to Atlanta - According to another report presented at the American College of Cardiology meeting, plaques seen on a CT scan predict heart disease. Researchers studied nearly 400 patients with an abdominal CT scan, finding that those who had extremely high levels of abdominal aortic calcium (or, plaque) had a 60% increased risk of coronary artery disease, as well an increased risk of mortality.

(March 12, 2010 - Insidermedicine) Less than half of individuals without known heart disease who are undergo invasive testing of the coronary blood vessels are found to have significant obstructions in these vessels, , according to research published in the New England Journal of Medicine. Here is some information about coronary angiography: • It is a procedure in which dye is injected into the body and then X-rays are used to visualize blood flow through the vessels that feed the heart. • It is usually done along with catheterization, in which a balloon-tipped catheter is threaded into the coronary arteries to achieve a better view of the vessels and remove any blockages that are found • The procedure carries with it a very small risk of a serious adverse event, including a heart attack or stroke Researchers from Duke University Medical Center in Durham used a national cardiovascular registry to identify nearly 400,000 individuals without known heart disease who underwent coronary catheterization to look for obstructions in the blood vessels that feed the heart. Left untreated, such obstructions can lead to a heart attack or stroke. The investigators also looked at whether certain characteristics of the individuals, including their sex, age, the presence of other medical conditions, and the results of less invasive tests, could predict who would eventually be diagnosed with one or more obstructions. Catheterization revealed the presence of an obstruction in only about 38% of the individuals tested. In addition, a lack of obstructive disease was confirmed in 39% of the individuals. Men, those who were older, those with insulin-dependent diabetes, and those with high cholesterol levels were all more likely to have obstructions in their coronary arteries. Those who had positive findings on noninvasive tests were only 28% more likely to have an obstruction than those who underwent no such testing. We spoke with Dr. Manesh Patel, one of the investigators of this study, who offered some further insight. Today’s research highlights the need to do a better job of identifying who is likely to have obstructive coronary artery disease before sending individuals for invasive coronary angiography and catheterization.

(March 11, 2010 - Insidermedicine) From Oxford – Inconsistent systolic blood pressure readings may be a predictor of stroke, according to a report published in The Lancet. Researchers followed over 8, 000 patients through seven doctor visits, finding that those who had the most variation in their systolic blood pressure had a 6x increased risk of stroke, while patients with the highest blood pressure had a 15x increased risk of stroke. From North Carolina – According to a report published in the journal Diabetes Care, anticipating a meal may be a risk factor for diabetes. Researchers compared over 500 diabetic patients to nearly 500 healthy controls, believing that when one anticipates or smells food, the nervous system triggers the body to salivate and thereby increases the production of insulin. They found that alterations to the gene that is responsible for this process may be a risk factor for type 2 diabetes. And finally, from Israel – According to a report presented at the annual meeting of the American Academy of Orthopaedic Surgeons, elderly patients who undergo knee replacement may have improved balance. Researchers studied 63 patients with knee arthritis, finding that total knee replacement resulted in not only pain relief, but also significantly improved balance and the ability to complete daily activiaties.
