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.

Sudden Unexpected Deaths (SUD)

Researchers Identify 5 Medical Conditions That May Contribute to Sudden Unexpected Death in NC

Sudden unexpected death (SUD) results from a malfunction of the heart and causes a rapid loss of blood flow through the body, leading to death. It is a very rapid process and may have few or no known warning signs. The overall survival rate for out-of-hospital arrest is only 5% to 10%. SUD is responsible for the deaths of upwards of 450,000 people in the US each year, with North Carolina experiencing an average of 32 SUD-related deaths each day.

The young woman’s hands were shaking as she doled out cash in exchange for the white, powdery substance. She then rushed back to her car, where she could be alone to experience the rush of pleasure that she had been craving. The few bites of sugared donuts and a 64-ounce soda would satisfy her addiction until lunchtime.

Sports Cardiology

Basic Elements of Sports Cardiology

Sports cardiology is becoming an autonomous subspecialty medical field in the US. Cardiologists are leading the way and defining their role within the space that treats the unique physiology of athletes and the needs of individuals who exercise. The American College of Cardiology has developed a Sports and Exercise Cardiology discipline within their guidelines to address the growing population of these cardiac patients.

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%.

Heart of a Trained Athlete

The Heart of a Trained Athlete: Does Excessive Training Risk Cardiovascular Health?

There’s no doubt that exercising on a regular basis is good for your health, as it helps control weight, combats a wide range of health conditions, and promotes better sleep, among countless other benefits. When it comes to the heart, exercise greatly improves cardiovascular function and can even lower some heart disease risk factors. The heart of a trained athlete who routinely exercises more than an hour a day even looks and performs differently than the heart of someone who never exercises. But could athletes who train too hard potentially have a higher risk of heart problems than recreational athletes?
