Oxygen Dimishes Heart Regeneration

Oxygen Diminishes the Heart’s Ability to Regenerate, Researchers Discover

Scientific research at UT Southwestern Medical Center previously discovered that the newborn animal heart can heal itself completely, whereas the adult heart lacks this ability. New research by the same team today has revealed why the heart loses its incredible regenerative capability in adulthood, and the answer is quite simpleoxygen.

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.

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?

Heart Shaped Fruits and Vegetables

Heart-Shaped Fruits and Vegetables Are Good for the Heart

When it comes to nutrition, it can be tough remembering which foods are good for you, let alone what parts of the body they benefit. Foods that are high in iron, such as lean red meat, turkey, egg yolks, dried beans, dried fruit, and whole grains, contribute to healthy hair; omega-3 fatty acids in oily fish are good for the skin; and probiotics in low-fat plain yogurt are good for the stomach. But who can remember all that?
