Heart Health

The heart beats about 2.5 billion times over the average lifetime, pushing millions of gallons of blood to every part of the body. This steady flow carries with it oxygen, fuel, hormones, other compounds, and a host of essential cells. It also whisks away the waste products of metabolism. When the heart stops, essential functions fail, some almost instantly.

Given the heart's never-ending workload, it's a wonder it performs so well, for so long, for so many people. But it can also fail, brought down by a poor diet and lack of exercise, smoking, infection, unlucky genes, and more.

A key problem is atherosclerosis. This is the accumulation of pockets of cholesterol-rich gunk inside the arteries. These pockets, called plaque, can limit blood flow through arteries that nourish the heart — the coronary arteries — and other arteries throughout the body. When a plaque breaks apart, it can cause a heart attack or stroke.

Although many people develop some form of cardiovascular disease (a catch-all term for all of the diseases affecting the heart and blood vessels) as they get older, it isn't inevitable. A healthy lifestyle, especially when started at a young age, goes a long way to preventing cardiovascular disease. Lifestyle changes and medications can nip heart-harming trends, like high blood pressure or high cholesterol, in the bud before they cause damage. And a variety of medications, operations, and devices can help support the heart if damage occurs.

Spring training: How to move from couch to 5K

A couch-to-5K program is a free or low-cost coaching plan designed to help would-be runners complete a 3.1-mile race. People should get their doctor’s approval before starting this regimen, especially if they have or are at risk for heart disease. For older or less fit people, a more gradual training program may be more appropriate. Also, many 5K races encourage walkers to participate, so people don’t necessarily have to run the race. In addition to providing structure and motivation to exercise more regularly, these races may also offer a way to support your local community or favorite charity. (Locked) More »

What is labile hypertension?

Labile hypertension is a condition marked by blood pressure readings that fluctuate far more than normal. It has many possible causes, including too much caffeine, anxiety, and stress, or the use of pain relievers known as NSAIDs. More »

Why worry about your waistline?

Growing numbers of Americans now have abdominal obesity (as measured by a large waist size), which puts them at a higher risk of cardiovascular disease. Abdominal fat (also known as visceral fat) pads the organs and is more likely to lead to unfavorable changes in blood sugar and other heart risk factors. Some people are predisposed to larger midsections because of their sex, genes, or ethnicity. But a reduced-carbohydrate diet that avoids added sugar, white flour, and starchy foods may help; so can intermittent fasting and regular exercise. More »

A different kind of heart attack

There are two basic types of heart attacks—type 1 and type 2. In type 1 heart attacks, rupture of a fatty plaque leads to a blood clot that completely blocks a coronary artery. In type 2 heart attacks, the problem is severely reduced flow through long-standing narrowing of a coronary artery. While both types are serious, type 2 may be the most concerning because its warning signs are often less dramatic and many men won’t seek medical care until it’s too late. Knowing the symptoms of type 2 attacks can enable men to recognize them. (Locked) More »

A more personalized approach to treating high cholesterol

Nearly one in three American adults has high levels of LDL, the most harmful type of cholesterol. The 2018 cholesterol treatment guidelines now take a more personalized approach on the best way to manage this common problem. As in the past, the new guidelines recommend an LDL-lowering statin drug for anyone who has already had a heart attack or (in most cases) a stroke. Adults ages 40 t0 75 who don’t have heart disease but who have diabetes and an LDL of 70 or higher should take a statin; so should anyone with an extremely high LDL (190 mg/dL or higher).

Prescription-strength omega-3 fatty acids to prevent heart disease?

A prescription drug called icosapent ethyl (Vascepa) that contains large doses of EPA (an omega-3 fatty acid found in fish oil) lowers high blood levels of triglycerides. For some people, it also may reduce heart attacks, strokes, and related events. Triglycerides, a type of fat in the blood, have been getting more attention of late for their role in heart disease. But the heart-protecting benefits of icosapent ethyl may also arise from calming inflammation, making blood less likely to clot, and preventing dangerous heart rhythms. (Locked) More »

The danger of “silent” heart attacks

Most people don’t realize that they could have a heart attack without even knowing it. Although these are known as “silent” heart attacks, a more accurate term may be “unrecognized” heart attack: people have symptoms but do not recognize them as coming from their heart. In the long run, these unrecognized heart attacks might be just as dangerous as recognized heart attacks. (Locked) More »
