How the Heart Works (Sides, Chambers, and Function)
The heart is a very important organ in the body. It is responsible for continuously pumping oxygen and nutrient-rich blood throughout your body to sustain life. It is a fist-sized muscle that beats (expands and contracts) 100,000 times per day, pumping a total of five or six quarts of blood each minute, or about 2,000 gallons per day.

Heart Attack Symptoms and Early Warning Signs
Recognizing heart attack symptoms and signs can help save your life or that of someone you love. Some heart attack symptoms, including left arm pain and chest pain, are well known but other, more nonspecific symptoms may be associated with a heart attack. Nausea, vomiting, malaise, indigestion, sweating, shortness of breath, and fatigue may signal a heart attack. Heart attack symptoms and signs in women may differ from those in men.
Lowering Triglycerides Naturally
Trigylcerides are fatty molecules that travel in the bloodstream. Excess sugar and fat can increase triglyceride levels. Triglycerides are also manufactured in the liver. The body uses triglycerides for energy, but excess triglycerides are a risk factor for heart attack, stroke, and obesity. Many lifestyle factors can influence triglyceride levels.
High Blood Pressure Treatment (Natural Home Remedies, Diet, Medications)
High blood pressure (hypertension) means high pressure (tension) in the arteries. Treatment for high blood pressure include lifestyle modifications (alcohol, smoking, coffee, salt, diet, exercise), drugs and medications such as ACE inhibitors, angiotensin receptor blockers, beta blockers, diuretics, calcium channel blockers (CCBs), alpha blockers, clonidine, minoxidil, and Exforge.
Peripheral Vascular Disease
Peripheral vascular disease (PVD) refers to diseases of the blood vessels (arteries and veins) located outside the heart and brain. While there are many causes of peripheral vascular disease, doctors commonly use the term peripheral vascular disease to refer to peripheral artery disease (peripheral arterial disease, PAD), a condition that develops when the arteries that supply blood to the internal organs, arms, and legs become completely or partially blocked as a result of atherosclerosis. Peripheral artery disease symptoms include intermittent leg pain while walking, leg pain at rest, numbness in the legs or feet, and poor wound healing in the legs or feet. Treatment for peripheral artery disease include lifestyle measures, medication, angioplasty, and surgery.
Heart disease (coronary artery disease) occurs when plaque builds up in the coronary arteries, the vessels that supply blood to the heart. Heart disease can lead to heart attack. Risk factors for heart disease include: Smoking High blood pressure High cholesterol Diabetes Family history Obesity Angina, shortness of breath, and sweating are just a few symptoms that may indicate a heart attack. Treatment of heart disease involves control of heart disease risk factors through lifestyle changes, medications, and/or stenting or bypass surgery. Heart disease can be prevented by controlling heart disease risk factors.
Blood Clots (in the Leg)
Blood clots can occur in the venous and arterial vascular system. Blood clots can form in the heart, legs, arteries, veins, bladder, urinary tract and uterus. Risk factors for causes of blood clots include high blood pressure and cholesterol, diabetes, smoking, and family history. Symptoms of a blood clot depend on the location of the clot. Some blood clots are a medical emergency. Blood clots are treated depending upon the cause of the clot. Blood clots can be prevented by lowering the risk factors for developing blood clots.
HDL vs. LDL Cholesterol (Good and Bad)
HDL (high-density lipoprotein), or the "good" cholesterol, and LDL (low-density lipoprotein), or the "bad" cholesterol, are lipoproteins that carry cholesterol through the veins and arteries of the body. HDL and LDL combined, is your "total" blood cholesterol. The difference between the two are that high levels of the "good," or HDL cholesterol, may protect against narrowing of the blood vessels in the body, which protects you against heart attack, stroke, and other cardiovascular diseases. But high levels of LDL, or the "bad" cholesterol, may worsen the narrowing of the blood vessels in the body, which puts you at a greater risk of stroke, heart attack, and cardiovascular diseases, some of which are life threatening.Triglycerides are found in body fat and from the fats you eat.
Symptoms of 12 Serious Diseases and Health Problems
Learn how to recognize early warning signs and symptoms of serious diseases and health problems, for example, chronic cough, headache, chest pain, nausea, stool color or consistency changes, heartburn, skin moles, anxiety, nightmares, suicidal thoughts, hallucinations, delusions, lightheadedness, night sweats, eye problems, confusion, depression, severe pelvic or abdominal pain, unusual vaginal discharge, and nipple changes. The symptoms and signs of serious health problems can be caused by strokes, heart attacks, cancers, reproductive problems in females (for example, cancers, fibroids, endometriosis, ovarian cysts, and sexually transmitted diseases or STDs), breast problems (for example, breast cancer and non-cancer related diseases), lung diseases (for example, chronic obstructive pulmonary disease or COPD, lung cancer, emphysema, and asthma), stomach or digestive diseases (for example, cancers, gallbladder, liver, and pancreatic diseases, ulcerative colitis, or Crohn's disease), bladder problems (for example, urinary incontinence, and kidney infections), skin cancer, muscle and joint problems, emotional problems or mental illness (for example, postpartum depression, major depression, post-traumatic stress disorder (PTSD), mania, and schizophrenia), and headache disorders (for example, migraines, or "the worst headache of your life), and eating disorders and weight problems (for example, anorexia or bulimia).
A heart attack happens when a blood clot completely obstructs a coronary artery supplying blood to the heart muscle. A heart attack can cause chest pain, heart failure, and electrical instability of the heart.
Tension Headache (Symptoms, Relief, Causes, Treatment)
A tension headache s one of the most common types of headaches, and the exact cause is not known. Factors that may contribute to tension or stress headaches are lack of sleep, increased stress (referred to as a stress headache), skipping meals, dehydration, medical diseases or conditions, anxiety, or changes at home, work, or school. Treatment of tension headaches include prescription and OTC medications, stress management, and treating any underlying illness or condition.
Angina is chest pain due to inadequate blood supply to the heart. Angina symptoms may include chest tightness, burning, squeezing, and aching. Coronary artery disease is the main cause of angina but there are other causes. Angina is diagnosed by taking the patient's medical history and performing tests such as an electrocardiogram (EKG), blood test, stress test, echocardiogram, cardiac CT scan, and heart catheterization. Treatment of angina usually includes lifestyle modification, medication, and sometimes, surgery. The risk of angina can be reduced by following a heart healthy lifestyle.
Fatty Liver (NASH)
Nonalcoholic fatty liver disease or NASH occurs due to the accumulation of abnormal amounts of fat within the liver. Fatty liver most likely caused by obesity and diabetes. Symptoms of fatty liver disease are primarily the complications of cirrhosis of the liver; and may include mental changes, liver cancer, the accumulation of fluid in the body (ascites, edema), and gastrointestinal bleeding. Treatment for fatty liver includes avoiding certain foods and alcohol. Exercise, weight loss, bariatric surgery, and liver transplantation are treatments for fatty liver disease.
Mercury is a naturally occurring element found in water, soil, and the air. Mercury also is contained in some fish, some of the products we use in the home, school, or dentist. Mercury poisoning can cause cognitive problems, dermatitis, tremor and other symptoms. Information about sources of mercury exposure, potential health effects, symptoms of exposure, fish that may contain mercury, consumer products that contain mercury, and ways to reduce your exposure to mercury is important for the health of you, and your family.
Heart Disease in Women
Heart disease in women has somewhat different symptoms, risk factors, and treatment compared to heart disease in men. Many women and health professionals are not aware of the risk factors for heart disease in women and may delay diagnosis and treatment. Lifestyle factors such as diet, exercise, tobacco use, overweight/obesity, stress, alcohol consumption, and depression influence heart disease risk in women. High blood pressure, high cholesterol, and diabetes also increase women's risk of heart disease. Electrocardiogram (EKG or ECG), stress-ECG, endothelial testing, ankle-brachial index (ABI), echocardiogram, nuclear imaging, electron beam CT, and lab tests to assess blood lipids and biomarkers of inflammation are used to diagnose heart disease. Early diagnosis and treatment of heart disease in women saves lives. Heart disease can be prevented and reversed with lifestyle changes.
Prediabetes is a situation where a person's blood sugar levels are higher than they should be, but aren't high enough to be diagnosed with type 2 diabetes. There are no signs or symptoms of prediabetes. Some of the risk factors for prediabetes are high blood pressure, high cholesterol, heart disease, smoking, family history, poor diet, and lack of activity. Diet changes along with other healthy lifestyle changes are important in treating prediabetes.
Migraine vs. Headache: Differences and Similarities
Headaches are the most common reason why a person goes to the doctor or other healthcare professional for treatment. There are different types of headaches, for example, migraine, tension, and cluster headaches. The most common type of headache is tension headache. Migraine is much less common. There are few similarities between migraine and other headaches, for example, the severity of the pain can be the same, mild, moderate, or severe; and they can occur on one side or both sides of the head. However, there are many differences between migraine and other types of headaches. Migraine headaches also have different names, for example, migraine with aura and menstrual migraine. Symptoms of migraine that usually aren't experienced by a person with another type of headache include nausea, vomiting, worsens with mild exercise, debilitating pain, eye pain, throbbing head pain. Migraine trigger include light, mild exercise, strong smells, certain foods like red wine, aged cheese, smoked meats, artificial sweeteners, chocolate, alcohol, and dairy products, menstrual period, stress, oversleeping, and changes in barometric pressure. Untreated migraine attacks usually last from 4 to 72 hours, but may last for weeks. Most headaches resolve within 24-48 hours. Doctors don't know exactly what causes migraine headaches; however, other headaches like tension headaches have more specific triggers and causes. Additional tests usually are required to diagnose migraine from other types of headaches, diseases, or other medical problems. Most headaches can be treated and cured with home remedies like essential oils, massage, and over-the-counter pain medication like acetaminophen (Tylenol) and NSAIDs (nonsteroidal anti-inflammatory drugs) like naproxen (Aleve, Anaprox, Naprosyn) or ibuprofen (Advil, Midol, Motrin). Most headaches resolve with OTC and home remedy treatment, while your doctor may need to prescribe medication to treat your migraines. If you have the "worst headache of your life," seek medical care immediately.
Carotid Artery Disease
The term carotid artery disease refers to the narrowing of the carotid arteries and can also be called carotid stenosis. Fatty substance buildup and cholesterol deposits, called plaque are the cause of the narrowing arteries. Carotid artery disease can be treated by following recommended lifestyle changes, taking prescription medications, and considering a procedure to improve blood flow, if your doctor believes it could help.
The cornea is the clear outer layer of the eye. If it is damaged by disease, infection, or injury, vision problems may occur. Corneal problems can be detected by having an eye exam. Corneal problems can be prevented by protecting the eyes from injury and avoiding contact with people who have eye infections.
Abnormal Heart Rhythms (Heart Rhythm Disorders)
Heart rhythm disorders vary from minor palpitations, premature atrial contractions (PACs), premature ventricular contractions (PVCs), sinus tachycardia, and sinus brachycardia, to abnormal heart rhythms such as tachycardia, ventricular fibrillation, ventricular flutter, atrial fibrillation, atrial flutter, paroxysmal supraventricular tachycardia (PSVT), Wolf-Parkinson-White syndrome, brachycardia, or heart blocks. Treatment is dependent upon the type of heart rhythm disorder.
Lipodystrophy (Acquired, Generalized, Inherited)
Lipodystrophy is a syndrome in which fat deposits accumulate all over the body, or sometimes just portions of it, like just the upper or lower body, or places on the skin where you give yourself daily allergy or insulin shots). You can be born with the generalized congenital or inherited type, or you can acquire it from HIV treatment drugs, infections, autoimmune diseases, trauma, or from repeated injections in the same place on the skin. The symptoms, treatment, and management depend upon the patient's type of lipodystrophy.
Low Cholesterol Diet
Cholesterol is naturally produced by the body, and is a building block for cell membranes and hormones. Low-density lipoprotein (LDL) cholesterol is the "bad" cholesterol, and high-density lipoprotein (HDL) cholesterol is the "good" cholesterol. High levels of LDL and low levels of HDL cholesterol put a person at risk for heart attack, stroke, transient ischemic attack (TIA or mini stroke), and peripheral artery disease. High cholesterol can be lowered by eating foods that lower cholesterol, for example, eat more high soluble fiber foods (oatmeal, oat bran, vegetables, and certain fruits), use olive oil, eat foods fortified with plant sterols and stanols, soy, nuts, and omega-3 fatty acids. Foods that raise LDL or bad cholesterol include foods high in saturated and trans fats, fatty meats, limit egg yolks, limit milk products, limit crackers, muffins, and snacks, and avoid unhealthy fast foods that are high in fat and sugar High cholesterol treatment includes lifestyle changes (diet and exercise), and medications such as statins, bile acid resins, and fibric acid derivatives.
Fitness: Exercise for a Healthy Heart
Regular exercise can help reduce the risk of heart disease. To achieve maximum benefits, do a mix of stretching exercise, aerobic activity, and strengthening exercise. Aim to get 20 to 30 minutes of aerobic exercise at least three to four times a week. Consult a doctor before exercising for the first time, especially if you have health problems.
Heart Attack Treatment
A heart attack involves damage or death of part of the heart muscle due to a blood clot. The aim of heart attack treatment is to prevent or stop this damage to the heart muscle. Heart attack treatments included medications, procedures, and surgeries to protect the heart muscle against injury.
Heart Attacks in Women
Heart disease, particularly coronary artery disease is the leading cause of heart attacks. Women are more likely to die from a heart attack than men. High cholesterol, high blood pressure, obesity, and high triglycerides are contributors to heart disease. Some of the common symptoms of a heart attack in women include chest pain, shortness of breath, nausea, feeling faint or woozy, and more. Heart disease can be prevented by lifestyle changes and controlling high blood pressure, cholesterol, weight, and diseases such as diabetes.
Dry eyes are caused by an imbalance in the tear-flow system of the eye, but also can be caused by the drying out of the tear film. This can be due to dry air created by air conditioning, heat, or other environmental conditions. Treatment may involve self-care measures, medications, or rarely, surgery.
Retinitis pigmentosa (RP) is a genetic condition that causes retinal degeneration and eventual vision loss. Symptoms include night blindness and tunnel vision. Visual field testing and electrophysiological testing are essential in diagnosing RP. Though there is no cure for RP, vitamin A therapy and an omega-3-rich diet may be recommended for patients to slow disease progression.
Heart Attack Pathology: Photo Essay
A heart attack is a layperson's term for a sudden blockage of a coronary artery. This photo essay includes graphics, pictures, and illustrations of diseased heart tissue and the mechanisms that lead to coronary artery disease, and possible heart attack. A coronary artery occlusion may be fatal, but most patients survive it. Death can occur when the occlusion leads to an abnormal heartbeat (severe arrhythmia) or death of heart muscle (extensive myocardial infarction).
Heart Attack Prevention
Heart disease and heart attacks can be prevented by leading a healthy lifestyle with diet, exercise, and stress management. Symptoms of heart attack in men and women include chest discomfort and pain in the shoulder, neck, jaw, stomach, or back. Women experience the same symptoms as men; however, they also may experience: Extreme fatigue Pain in the upper abdomen Dizziness Fainting Leading a healthy lifestyle with a heart healthy low-fat diet, and exercise can help prevent heart disease and heart attack.
High Cholesterol: Frequently Asked Questions
Cholesterol occurs naturally in the body. High blood cholesterol levels increase a person's risk of developing heart disease, heart attacks, strokes, TIAs, and more. In addition to medication (fibrates, statins, bile acid sequestrants, and niacin), lifestyle changes can be made to lower blood cholesterol levels
Heart Disease Treatment in Women
Heart disease treatment in women should take into account female-specific guidelines that were developed by the American Heart Association. Risk factors and symptoms of heart disease in women differ from those in men. Treatment may include lifestyle modification (diet, exercise, weight management, smoking cessation, stress reduction), medications, percutaneous intervention procedure (PCI), and coronary artery bypass grafting (CABG). Heart disease is reversible with treatment.
Vitamins & Exercise: Heart Attack Prevention Series
Vitamins and exercise can lower your risk for heart attack and heart disease. Folic acid, vitamins, and homocysteine levels are interconnected and affect your risk for heart disease or heart attack. For better heart health, avoid the following: fried foods, hard margarine, commercial baked goods, most packaged and processed snack foods, high fat dairy, and processed meats such as bacon, sausage, and deli meats. Antioxidants and exercise also play a key role in heart attack and heart disease prevention. Lower your risk factors for heart disease and heart attack by: lowering cholesterol, lowering blood pressure, diabetes prevention, and smoking cesssation. Here are a few things you can do to prevent heart attacks: Eat whole, natural, fresh foods, eat five to 10 servings of fruits and vegetables daily, eat more omega-3 fatty acids, drink water, tea, non-fat dairy and red wine, eat lean proteins, limit glycemic foods, and exercise daily.
Heart Attack Prevention Overview
Heart attacks are the major causes of unexpected, sudden death among men and women. A heart attack also is a significant cause of heart failure. The process of developing atherosclerosis (hardening of the arteries) begins early in life. Heart attack prevention should begin in childhood because the atherosclerosis process can not be reversed. The risk of having a heart attack increases if you have diseases or conditions such as high blood pressure, diabetes, and other heart conditions. You can lowering your risk of having a heart attack by: Lifestyle changes, for example: Diet Exercise Quit smoking Control high blood pressure, diabetes, and other diseases that are risk factors) In some cases, medication is the most effective way of preventing a heart attack
