Hearts of Healthy People With Gene Mutations May Be 'Primed to Fail'

Posted 18 days ago by Drugs.com

WEDNESDAY, Nov. 23, 2016 – Certain gene mutations can increase the risk of heart failure in healthy people, researchers report. It had been believed that gene mutations in a protein called titin affect only people with dilated cardiomyopathy, one of the most common forms of inherited heart disease. But this study of more than 1,400 adults found that the hearts of healthy people with mutations in this gene may be "primed to fail" if affected by other genetic or environmental factors. About 35 million people worldwide may be at risk, the researchers said. "Our previous work showed that mutations in the titin gene are very common in people diagnosed with heart failure. Around 1 percent of the general population also carry these mutations, but until now it wasn't known if these are 'silent' gene changes or changes that can adversely affect the heart," said co-author Dr. Antonio de Marvao ...

Marijuana Use Tied to Rare, Temporary Heart Malfunction

Posted 13 Nov 2016 by Drugs.com

SUNDAY, Nov. 13, 2016 – Marijuana use might raise the risk of a rare, temporary heart muscle malfunction that can feel like a full-fledged heart attack, a new study suggests. People who used marijuana were almost twice as likely as non-users to suffer a bout of stress cardiomyopathy, a condition also known as takotsubo, said study co-author Dr. Amitoj Singh. He is chief cardiology fellow at St. Luke's University Health Network in Bethlehem, Pa. Further, pot users experiencing takotsubo were more likely to suffer a cardiac arrest or require an implanted defibrillator, compared with non-users with takotsubo, Singh said. Cardiac arrest is when the heart suddenly stops beating. "Marijuana does not appear to be entirely safe, as some of the lobbyists for marijuana are arguing," Singh said. But the study did not prove that pot causes takotsubo. Singh was to present his findings Sunday at the ... Read more

Childhood Cancer Treatment May Raise Adult Heart Disease Risk

Posted 5 Jan 2016 by Drugs.com

MONDAY, Jan. 4, 2016 – Children who survive cancer may face a higher risk of heart disease as adults, new research suggests. The lingering effects of the treatments that saved their lives as children may trigger the development of heart abnormalities that might not cause apparent symptoms, the researchers explained. The investigators found that heart disease appears to affect between 3 percent and 24 percent of pediatric cancer survivors by the time they reach their 30s. Those figures rose to between 10 and 37 percent among patients 40 and older, the study found. However, while the study revealed a link between childhood cancer treatment and later heart disease, it didn't prove cause-and-effect. "The prevalence of these cardiac findings might be expected in an older adult population, but not necessarily in this young a population," said study lead author Dr. Daniel Mulrooney. ... Read more

Why Women Should Lower Their Holiday Stress Level

Posted 23 Nov 2015 by Drugs.com

SUNDAY, Nov. 22, 2015 – The stress of making holiday time a happy time can put women at risk for heart problems, an expert warns. The pressure of tasks like cooking, buying presents, and organizing family gatherings can lead to stress that can damage their hearts, according to Dr. Karla Kurrelmeyer, a cardiologist with Houston Methodist Hospital's Heart and Vascular Center. "We have seen more than a few cases of stress-induced cardiomyopathy around the holidays. This occurs when women are under great amounts of stress for a short period of time and that stress is compounded with another traumatic event, such as a death in the family, a car accident, loss of money, etc. If it is ignored, it can be fatal," she said in a hospital news release. Stress-induced cardiomyopathy occurs when stress hormones weaken the left ventricle, the heart's main pumping chamber. The condition is most common ... Read more
