Sleep problems such as insomnia, sleep apnea, and periodic limb movements can disrupt sleep. A lack of sleep or fragmented sleep can prevent people from getting enough restorative deep sleep and may cause unhealthy blood pressure surges. These problems may increase the risk of cerebrovascular disease (including stroke and unrecognized silent strokes) and cognitive issues.

People who routinely exercise far more than the federal activity guidelines recommend will likely reap heart and longevity benefits. But they should be sure not to neglect other heart-healthy habits, such as getting routine check-ups, keeping tabs on their risk factors, following a healthy diet, and paying attention to heart-related symptoms.

A thoracic aortic aneurysm (a weakened area in the wall of the upper section of the aorta) may require surgical repair if it grows too large. Aneurysms in the area called the descending aorta can sometimes be repaired with a less invasive endovascular technique.

A normal pulse rate is between 60 and 100 beats per minute. Possible causes of an elevated pulse include fever, anemia, anxiety, or an overactive thyroid. Other possibilities include too much caffeine, decongestants, or being out of shape.

Orthostatic hypotension is a drop in blood pressure when standing up. If it ever leads to loss of consciousness or a fall, it can be dangerous.

Large studies have not found evidence of higher rates of heart attacks, strokes, or other cardiovascular diseases in people who eat up to one egg per day.

Metformin, a medicine prescribed to treat type 2 diabetes, also has cardiovascular benefits and is used off-label to treat other conditions. Interest is growing in its potential to help lower risks for other serious health problems and even slow aspects of aging, but which of these benefits, if any, apply to people who do not have diabetes?

I?ve read that a normal resting heart rate is between 60 and 100 beats per minute. Mine runs around 45 to 48. Should I be concerned? I have been a runner for 42 years and have completed seven marathons.

Lightheadedness is a feeling of wooziness or faintness. It is commonly caused by dehydration, drug side effects, blood pressure drops, low blood sugar, heart disease, or stroke.

A second opinion from a cardiologist may be helpful for people considering whether to undergo a specialized heart procedure. Such consultations may be increasingly appropriate as new, minimally invasive treatments for various heart problems become more widely available and more specialized. Others who might seek a second opinion include people with heart-related symptoms that persist despite treatment, who have been told they have no more options.
