To prevent heart valve disease caused by rheumatic fever, see your doctor if you have signs of a strep infection.

La actividad física es parte de un estilo de vida saludable para el corazón.

Physical activity is one part of a heart-healthy lifestyle.

Early treatment for a heart attack can prevent or limit damage to the heart muscle. Act fast by calling 9–1–1 at the first symptoms of a heart attack. Immediate treatments include aspirin, nitroglycerin, oxygen therapy, and treatment for chest pain. Your doctor may initiate treatment to restore blood flow through the blood vessels supplying the heart, such as clot-busting medicines and percutaneous coronary intervention (PCI). Other treatments include medicines, medical procedures, heart-healthy lifestyle changes, and cardiac rehabilitation.

Treatments for atherosclerosis may include heart-healthy lifestyle changes, medicines, and medical procedures or surgery—such as percutaneous coronary intervention (PCI), coronary artery bypass grafting (CABG), or carotid endarterectomy.

En general, los beneficios de la actividad física que se practica con regularidad superan los riesgos. En raras ocasiones se presentan problemas del corazón, como por ejemplo, arritmias, paro cardíaco súbito y ataque cardíaco.

Debe preguntarle siempre a su médico qué tipo y qué cantidad de actividad física puede realizar sin peligro.

Many factors such as age (being younger than two years old or 65 of older), smoking, and other medical conditions such as heart failure, diabetes, COPD (chronic obstructive pulmonary disease), or people who have weak immune systems due to HIV/AIDS, chemotherapy (a treatment for cancer), or organ or blood and marrow stem cell transplant procedures can increase your chances of getting pneumonia and having more severe pneumonia.

Your doctor will diagnose pneumonia based on your medical history, a physical exam, and results from certain diagnostic tests such as a chest x ray, blood tests, or blood culture. Your doctor may recommend other tests—sputum test, chest computed tomography (CT) scan, pleural fluid culture, pulse oximetry, or bronchoscopy—if you're in the hospital, have serious symptoms, are older, or have other health problems.
