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.

Diabetes: Complexity Lost

Diabetes: Complexity Lost

For millions of people in the US living with type 1 or type 2 diabetes, measuring the daily rise and fall of blood glucose (sugar) is a way of life. Our bodies energy is primarily governed by glucose in the blood, and blood sugar itself is exquisitely controlled by a complicated set of network interactions involving cells, tissues, organs, and hormones that have evolved to keep the glucose on a relatively even keel, pumping it up when it falls too low or knocking it down when it goes too high. This natural dynamic balance becomes lost when someone develops diabetes.

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.

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.

High Cholesterol May Delay Pregnancy

High Cholesterol May Delay Pregnancy

Couples may take longer to conceive a child when one or both partners has high cholesterol, according to a new study published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism (JCEM).

Cholesterol is a waxy, fat-like substance found in all cells of the body. About a third of American adults – 71 million – have high levels of low-density lipoprotein, or “bad” cholesterol, according to the Centers for Disease Control and Prevention. Only one of every three adults with high LDL cholesterol has the condition under control.

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%.

Little-Known Medicinal Plants and Herbs

Little-Known Medicinal Plants and Herbs

Plants and herbs are used in numerous pharmacological compounds. Many lesser-known ones have entered the mainstream and are used to treat health issues. These are most often found in vitamin shops, health food stores, drug stores, and even supermarkets. Here we are highlighting 3 herbs that are not commonly known, but may be headed to the forefront in the near future.

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?
