Geneticists Repair Mutation in Human Embryo

Posted 2 Aug 2017 by Drugs.com

WEDNESDAY, Aug. 2, 2017 – In a first-ever experiment, geneticists have successfully modified a human embryo to remove a mutation that causes a life-threatening heart condition. This is the first study to demonstrate that a gene-editing technique can be used in human embryos to convert mutant genes back to their normal version, the researchers said. The new procedure tackled a genetic mutation in human embryos that causes hypertrophic cardiomyopathy, an inherited condition in which the heart muscle becomes abnormally thick. The mutation was successfully repaired in 72 percent of 18 embryos that were created in a lab using sperm from a male donor who carries the hereditary heart condition, said team member Dr. Paula Amato. She is an adjunct associate professor of obstetrics and gynecology at Oregon Health & Science University (OHSU) in Portland. The procedure also might work in other ... Read more

Implantable Defibrillator May Not Mean End to Sports

Posted 5 Jun 2017 by Drugs.com

MONDAY, June 5, 2017 – Competitive sports may be safe for many athletes who have an implantable cardioverter defibrillator (ICD), new research suggests. The four-year study followed 440 athletes with ICDs who participated in vigorous sports such as running, basketball, soccer, tennis, volleyball, skiing and snowboarding. An ICD is a battery-powered device placed under the skin. When it detects an abnormal heart rhythm (arrhythmia), it delivers an electric shock to restore normal rhythm. In 2015, the American Heart Association said participating in competitive sports may be considered for athletes with ICDs. That advice was based on a study that followed hundreds of athletes with the devices for two years. This longer study of 10- to 60-year-olds followed competitive athletes at the national and international level, high school and college athletes, and others. During the study period, ... Read more

Increasing Numbers of Pregnant Women Also Have Heart Disease

Posted 22 May 2017 by Drugs.com

MONDAY, May 22, 2017 – Many more American women with heart disease are choosing to have babies, a new study finds. Researchers looked at more than 81,000 women with heart disease from 2003 to 2012. They found that the proportion who had babies rose 24 percent during that time. "We learned that in addition to the high and growing prevalence of women with heart disease delivering babies, the reasons are mainly related to increases in women delivering babies with diseases such as cardiomyopathy, adult congenital heart disease, and pulmonary hypertension," study author Dr. Kathleen Stergiopoulos said in a Stony Brook University news release. She is a specialist in heart disease in women at the Stony Brook Heart Institute. The researchers also found that major heart problems, such as heart failure and heart rhythm problems, in pregnant women with heart disease increased by nearly 19 ... Read more

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

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

Better Treatments Helping People With Enlarged Hearts Live Longer: Study

Posted 16 Mar 2015 by Drugs.com

SATURDAY, March 14, 2015 – Advances in treatment mean that people with an enlarged heart now live longer than they did 10 or 15 years ago, a new study finds. Researchers examined death rates and causes of death between 1992 and 2011 among 1,000 adults with the condition, which is clinically known as hypertrophic cardiomyopathy (HCM). It's a genetic condition in which the walls of the heart grow abnormally thick, impeding the heart's performance. As explained in a news release from the Minneapolis Heart Institute Foundation, the condition can trigger a dangerously rapid heart rhythm that can result in sudden cardiac death. However, this risk can be controlled with an implanted defibrillator (ICD), a device that shocks the heart back into normal rhythm. During the study period, death rates among the people with enlarged hearts were about the same as among adults in the general ... Read more
