The human heart is one of the hardest-working organs in the body. It never takes a day off and requires a continuous supply of energy to keep beating. To meet these enormous energy demands, heart cells mainly rely on fats as fuel. For decades, researchers have viewed this ability to burn fat as a sign […]

Doctors have long treated heart disease and cancer as two separate health problems. Heart specialists focus on the cardiovascular system, while cancer specialists focus on tumors and abnormal cell growth. However, scientists are increasingly finding that these two major diseases may be more closely connected than previously believed. A new study led by researchers at […]

For decades, pacemakers have helped millions of people live longer and healthier lives. These small devices are implanted inside the body and send electrical signals to the heart when its natural rhythm becomes too slow or irregular. Pacemakers are considered one of the most successful medical technologies ever developed. They have saved countless lives by […]

The last time your blood pressure was measured, did you rush to the appointment while sipping coffee? Were you perched on an exam table with your legs dangling or your arm hanging? Were you chatting with a medical staff member or scrolling social media on your phone? Was your bladder full? Any of these actions […]

For many years, doctors have encouraged people with obesity to lose weight in order to improve their heart health. Even modest weight loss can reduce strain on the heart, improve blood sugar levels, and lower blood pressure. Now, a major new study suggests that the latest generation of weight-loss medications may deliver significant blood pressure […]

Millions of older adults worry about losing their strength and independence as they age. Many people fear not only serious illnesses such as heart disease or cancer but also the gradual loss of physical function that can make everyday tasks difficult. This condition, known as frailty, affects a growing number of older people around the […]

A new study involving almost one million patients is challenging one of the most influential ideas in modern heart care. Researchers from Tulane University report that not all women with atrial fibrillation have a higher risk of stroke than men, despite what many medical guidelines have assumed for years. The findings could eventually affect how […]

Many people think of heart disease, diabetes, obesity, and kidney disease as separate medical problems. In reality, they are often closely connected. A person who develops obesity may later develop diabetes. Diabetes can damage the kidneys and blood vessels. Kidney disease can increase the risk of heart failure, heart attack, and stroke. This complex relationship […]

A team of engineers and health researchers from the University of New South Wales (UNSW) has developed a tiny wearable device that could change how people monitor their heart and lung health. The lightweight patch, which weighs just over three grams, is designed to stick to the chest like a bandage and continuously track important […]

For many years, scientists believed that helping the heart burn more fat for energy was generally a good thing. After all, fat is the heart’s main fuel source under normal conditions. Every day, the heart beats more than 100,000 times and needs a huge amount of energy to keep blood moving throughout the body. Most […]

Modern cancer treatment has entered a new era thanks to immunotherapy. Instead of directly attacking cancer cells with chemicals or radiation, immunotherapy encourages the immune system to do the job itself. This approach has helped many patients live longer and has changed the outlook for several types of cancer. One of the most widely used […]

When doctors discover that one of the heart’s major arteries is completely blocked, it often sounds like very bad news. Coronary arteries supply oxygen-rich blood to the heart muscle, and a blockage can reduce blood flow and damage the heart. For many years, doctors believed that heart muscle located beyond a long-term blockage was often […]
