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?

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.

Standard definitions consider a healthy body mass index (BMI), a calculation based on a person's height and weight, as between 18.5 and 24.9. Studies have found that a higher BMI increases risk for heart disease, diabetes, and some types of cancer. However, even if their BMI does not fall into the category of overweight, people who gain five or more pounds may be at risk for health problems, especially if the weight gain is belly fat. The best approach is a combination of aerobic exercise, strength training, and a healthy diet.

Telemedicine visits combined with self-measured blood pressure readings may help control high blood pressure better than traditional clinic visits, according to a 2024 study.

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.
