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.

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.

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.

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.

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.

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.

New guidelines for managing atrial fibrillation focus on lifestyle habits to prevent and control the disorder. One recommendation is for people to limit alcohol to one drink per day, or ideally less. Another is for people who are overweight or obese to lose weight, either by striving for a body mass index no greater than 27 or by shedding at least 10% of their body weight. The guidelines also suggest that people get three to four hours of exercise per week. And people with afib who snore should consider getting tested for sleep apnea.

Every year, an estimated 600,000 people in the United States develop a blood clot deep inside the leg, known as deep-vein thrombosis. These clots usually develop in the lower leg, thigh, or pelvis but occasionally the arm. The affected area may be tender or painful, swollen, red or discolored, and warm to the touch. If a clot breaks free and travels to a lung, it can cause a pulmonary embolism. Symptoms of a pulmonary embolism include difficulty breathing that happens suddenly, a fast or irregular heartbeat, coughing up blood, and chest pain or discomfort, which usually worsens with a deep breath or coughing.
