Heart rate variability measures the variance in time between each heartbeat. Research has found that a lower HRV is associated with anxiety disorders and earlier death from heart diseases, while a higher HRV may indicate better cardiovascular fitness and greater resilience to stress. However, HRV is a highly-specific measurement and […]

You should recover from a stent procedure by resting, staying away from vigorous physical activity, and following your doctor’s recommendations for medication. Many patients are able to recover from a stent and return to work within a week, though it may take longer for others. You’ll also want to look […]

You should prepare for a stent procedure by staying hydrated, talking with your doctor about medications to avoid, and making arrangements for after the surgery. Angioplasty and stent procedures are not especially taxing, but there can be complications. Here’s how to prepare for a stent so you can reduce your […]

A stent is a tiny mesh tube that is inserted into an artery to prop it open and improve blood flow to the heart. Stents can be life-saving during a heart attack, and this is a common treatment to restore blood flow when there’s a dangerous blockage. While not always […]

Chronic stress is a risk factor for heart disease and it may lead to a heart attack. Stress can cause high blood pressure, increase heart rate, and lead to overeating, smoking cigarettes, and drinking more alcohol — all of which are major risk factors for a heart attack. Sudden stress […]

Aspirin can help prevent a heart attack from getting worse if you take it after the onset of symptoms. Taking a daily baby aspirin may also reduce the chance of a heart attack if you’re at high risk for one, or if you’ve already had one. Aspirin is a blood […]

You can calculate total cholesterol by doing a blood test called a lipid panel with your doctor. Your doctor will evaluate your total cholesterol level, along with each element of your cholesterol – LDL, HDL, and triglycerides – to determine if you need any treatment to lower cholesterol. Doctors will […]

You can lower triglycerides by exercising, losing weight, and drinking less alcohol. If your triglycerides levels are very high – like over 500 milligrams per deciliter – your doctor may also recommend medication to lower triglycerides. Triglycerides, like cholesterol, are associated with a higher risk of heart disease if your […]

You can know if your chest pains are serious by assessing your symptoms and medical history. If you feel severe chest pain and also exhibit risk factors for heart disease – like high blood pressure, high cholesterol, or diabetes – it may indicate a serious heart condition like a heart […]

Heart failure is a condition where the heart no longer functions properly and cannot pump enough blood throughout the body. While there aren’t always clear symptoms of heart failure, there are factors that indicate you’re at a higher risk: high blood pressure, high cholesterol, smoking, and obesity. There isn’t a […]

A heart murmur is when blood flows more rapidly than normal through the heart. Heart murmurs can be innocent and frequently happen during pregnancy, physical activity, or childhood growth spurts. Heart murmurs can also be abnormal and dangerous, like when they are associated with congenital heart defects or problems with […]

A heart attack is not as dangerous as cardiac arrest, though both heart conditions are serious. A heart attack occurs when blood flowing to the heart is blocked, while cardiac arrest occurs when the heart suddenly stops pumping blood. Cardiac arrest is fatal 89% of the time – a heart […]

A new study found people who regularly drink coffee tend to have stronger bones than those who don’t. Past research was inconclusive on whether java supported or detracted from bone health. Other research has linked coffee to a host of health benefits, especially for heart health. Visit Insider’s homepage for […]

The main signs of a heart attack are opressive discomfort or heaviness in the centre of the chest, paired with discomfort in the neck, throat, jaw, and the left side of the chest or arm. Women and older adults may experience subtler signs of a heart attack such as unusual […]

A Duke University medical team became the first in the U.S. to successfully transplant a previously-dead adult heart, a procedure known as “donation after circulatory death” or DCD. The procedure could dramatically increase the number of transplant hearts available for patients in need, allowing for up to 30% more donors […]

At the beginning of the year, Apple CEO Tim Cook said his company’s “greatest contribution to mankind” would be in health. So, can the Apple Watch help spot heart problems? A study published Wednesday says yes. There are caveats. The study did not use the most recent Apple Watch, which […]

The average billed cost of a heart transplant is an estimated $US1,382,400, according to consulting firm Milliman, and other organs aren’t much cheaper. Doctors say transplant centres are strong revenue sources for hospitals; they charge high service fees, which factor into the overall cost, to help meet their bottom line. […]

Two months ago, Apple CEO Tim Cook said his company’s “greatest contribution to mankind” would be in health. A new study led by Stanford researchers provides a glimpse at how that vision is beginning to take shape. The preliminary analysis suggests that the Apple Watch can accurately detect some heart […]

The true effects of e-cigarettes on human health are just beginning to emerge. Risks of vaping include inhaling toxic metals like lead and potentially doubling one’s risk of a heart attack, according to a new study published by UCSF researchers. Despite these emerging health concerns, e-cig companies like Juul, the […]

There’s even more evidence that two forms of exercise – cardio and strength training – can help protect you against some of the wear and tear of ageing. A new study in the Journal of the American Heart Association suggests that older folks who clock in more movement see better […]

Measurements of your belly can tell you a lot about how healthy you are. Researchers are learning that the amount of fat we hold around our waistlines is a good indicator of our overall health. In a new study of more than 5,000 older people, researchers found that people’s waist-to-hip […]

Cardio could be the closest thing to a miracle drug that we have, but doing it shouldn’t take a whole day. Instead, the available evidence suggests there’s an ideal window for exercises like cycling, swimming, or brisk walking – and it’s under an hour. All of these moves raise your […]

A hot new type of workout called high-intensity interval training, or HIIT, promises the benefits of a traditional workout in under 10 minutes. Though HIIT may sound like hype, a growing body of research suggests this may be one of the best ways to get fit. We recently tried one […]

If you’re searching for an all-natural way to lift your mood, preserve muscle tone, and protect your brain against the decline that comes with ageing, look no further than the closest mirror. One of the most powerful means of reaping these benefits is exercise – and in many cases, you […]

Researchers have looked at more than a dozen studies on marijuana’s effect on the heart, and their takeaway is far from conclusive. That finding contradicts a study published in August that claimed marijuana users faced a threefold higher risk of dying from hypertension than nonusers. The August study had some […]

We know sitting is bad for our health, but a recent study helps explain why. People who sit too long have signs of “subclinical injury” – not bad enough to necessitate immediate treatment but potentially dangerous over a long period of time. Exercise seems to help, but the most important […]
