Heart Failure

Complex Proteins and Cardiac Death

Getting to the Heart of the Heart

For years, a multidisciplinary team of Johns Hopkins researchers has tracked an elusive creature, a complex of proteins thought to be at fault in some cases of sudden cardiac death.

Monitoring Heart Failure

Monitoring Heart Failure

A new miniaturized, wireless monitoring system, implanted in the pulmonary artery, is helping keep patients with severe heart failure out of the hospital. Houston Methodist Hospital is the first institution in Houston to offer this to heart failure patients.

Thyroid Hormones

Restoring Thyroid Hormones in the Heart May Prevent Heart Disease From Diabetes

Administering low doses of a thyroid hormone to rats with diabetes helps restore hormone levels in their hearts and prevented deterioration of heart function and pathology, according to a new study by the New York Institute of Technology College of Osteopathic Medicine Professor and Biomedical Sciences Chair A. Martin Gerdes.

Kawasaki Disease

A Disease Scattered to the 4 Winds

In 2013, a mother arrived at a Texas clinic with her 4-year-old son in tow. Three weeks earlier, he had been diagnosed with ringworm and given an antifungal (griseofulvin), but he had recently stopped eating. Concerned about his loss of appetite, she patiently waited for a doctor to see her son. When the doctor finally saw them, she informed him that it had been 2 days since her son ate. He also had begun to develop a rash on his face, trunk, and extremities and had some nasal congestion and an occasional cough. The doctor conducted a physical exam on the boy but there was nothing extraordinary other than his presenting symptoms: a sand paper–like erythematous rash and reddish mucosal tissue in his mouth and throat. He wasnt feverish, his cough was not persistent, and a rapid strep test was negative. Believing he had contracted a virus, the doctor sent him home to rest.

Death During Sex

Death During Sex

Over-activity of the sympathetic nervous system (which controls ejaculation as well as the actions of the heart and blood vessels) can bring on sudden death due to cardiac arrest during or shortly after sexual activities. In 2011, Dr. Issa Dahabreh, affiliated with Tufts Medical Center in Boston, conducted an analysis of 14 studies along with a colleague, Jessica Paulus, to quantify the risk of having a heart attack or sudden cardiac death brought about by sex. The team of doctors discovered that people are 2.7 times more likely to have a heart attack either during or shortly after sex compared to when they are inactive. However, they point out that the period of risk is brief, that is, either during the act itself or about 1 to 2 hours after sexual activity. They go on to report that individual risk is minimal. The researchers further highlight the fact that other studies have shown that regular physical activity reduces the risk of heart attacks or sudden cardiac death by 30%.
