How thyroid hormone affects the heart
Too little thyroid hormone can interfere with the heart's pumping strength and raise cholesterol and blood pressure. Too much thyroid hormone can cause the heart to race and raises the risk of developing heart failure.
Digoxin useful … with restrictions
Although digoxin is commonly used in atrial fibrillation, it can increase the risk of death and should be used only in very low doses and as a second rate-control drug when a safer drug is not adequate.
Promising news about heart failure
Serelaxin, a new drug derived from hormones that cause muscle relaxation, appears to reduce the symptoms of heart failure, organ damage from poor blood flow, and heart failure deaths.
Tests to evaluate risk of heart attack
Diabetes increases the risk of developing heart disease. Among people with diabetes, a variety of imaging tests can be used to estimate the risk of having a heart attack or stroke.
Heart beat: An egg a day may be A-okay
In people without diabetes, an egg a day does not increase the risk of heart attack or stroke. In all people, eating eggs lowers the risk of hemorrhagic stroke.
Heart beat: Overeating? Blame fructose
Fructose may not signal the brain to stop eating when the stomach is full, which could make it easier to overeat. Since sugar is half fructose, this offers another reason to cut back consumption of sugar-sweetened beverages and other sugary foods.
Heart beat: Aspirin after heart attack or stroke
Aspirin reduces the risk of a second heart attack or stroke by 20%, yet doctors prescribe it for less than half the people who might benefit from it.

Ways to reduce your dependence on blood pressure medications
Many heart medications interact with certain foods, beverages, vitamins, dietary supplements, over-the-counter drugs, and other prescription medications, causing the heart drug to be more powerful or less effective.
Avoid these with heart medications
Chest pain caused by a heart attack is often described as a squeezing type of pressure that emerges slowly, rather than a sharp, quick pain. A heart attack may cause shortness of breath, sweating, nausea, lightheadedness, or loss of consciousness.
When a drug you take comes under fire
When a medication receives negative press, asking whether the drug caused the side effect, how many people it affected, and whether the side effect was worse than the disease the drug treats can help you weigh the drug's benefits against its risks.
How to prepare for a safe vacation
Before going on vacation, people with heart disease should make sure it's safe to fly and pack pertinent medical information and more than enough medications. Buying air ambulance or repatriation insurance before leaving home may also be wise.

Ask the doctor: The trouble with the body mass index
Body mass index (BMI) is easy to measure and is a good rough instrument for determining whether a person is overweight or obese. But it does not account for individual differences in body shape and muscularity.
Ask the doctor: Is warfarin plus aspirin safe?
People taking the anticoagulant drug warfarin (Coumadin) for atrial fibrillation may sometimes need to take a second type of anti-clotting drug-an antiplatelet drug such as aspirin. This dual therapy adds to bleeding risk, but lowers stroke risk.
How to lower your stroke risk
A few factors that boost the odds of having a stroke can't be changed, like age and family history. But there are a surprising number of things that can be done to prevent stroke.

Prevent kidney disease to prevent heart disease
Adopting a heart-healthy diet doesn't necessarily mean drastic lifestyle change. Small dietary tweaks may suffice. Pick tasty substitutes for saturated fat, trans fat, sugar, sodium, and calories while increasing fiber and nutrient intake.
When to seek genetic testing for heart disease
Thickening of the heart-hypertrophic cardiomyopathy-is a genetic disease. People with a first-degree relative who has the disease have a 50-50 chance of having it, too. Family genetic testing is indicated, as early detection can prevent sudden death.
Tell your dentist about your heart problems
Although dental disease and heart disease share many of the same risk factors, the American Heart Association says there's no convincing evidence that dental disease causes heart disease. People with valve disorders need special dental care.

Vitamin E was once recommended by doctors to prevent heart attacks, but the studies supporting that advice are contradicted by newer and better research. Vitamin E supplements are no longer recommended for prevention of either heart disease or cancer.
Ask the doctor: Smoking: cut back or cut it out?
It's important to quit smoking. It's not clear whether there's a benefit to merely cutting back on the number of cigarettes smoked. Smoking-cessation methods are most effective in the context of a comprehensive cessation program.
Don't skip cardiac rehab after a heart event
A cardiac rehabilitation center is a lot more than a gym. After a major heart event-or even before one happens-cardiac rehab is proven to decrease cardiac risk factors. Get it if your doctor advises it; ask about it if your doctor doesn't.
For a healthy brain, treat high blood pressure
Studies suggest that blood pressure-lowering drugs may do more than treat hypertension-they may also delay or prevent dementia. This isn't yet proven, but maintaining a healthy blood pressure and reducing other heart risks likely lowers dementia risk.
Aortic valve disease: Surgical or transcatheter replacement?
A stiff, poorly working aortic valve is a life-threatening condition. Open-heart surgery to replace the aortic valve is the gold standard. For some individuals less invasive transcatheter aortic valve replacement is an appropriate option.
