An implantable cardioverter-defibrillator (ICD) is an electronic device that tracks the heart rate and restores a normal rhythm, if required. It is first-line treatment for patients who are at risk of sudden cardiac death. ICD is useful in reducing the death rate amongst patients suffering from cardiac arrest, heart failure, reduced ejection fraction (reduced amount of blood pumped out of heart’s chambers), specific structural heart diseases. An ICD detects and corrects the abnormal rhythm of the heart. Read more: How Long Can You Live With an Implanted Defibrillator? Article

Congestive Heart Failure (CHF) Symptoms, Treatment, and Life Expectancy
Congestive heart failure (CHF) refers to a condition in which the heart loses the ability to function properly. Heart disease, high blood pressure, diabetes, myocarditis, and cardiomyopathies are just a few potential causes of congestive heart failure. Signs and symptoms of congestive heart failure may include fatigue, breathlessness, palpitations, angina, and edema. Physical examination, patient history, blood tests, and imaging tests are used to diagnose congestive heart failure. Treatment of heart failure consists of lifestyle modification and taking medications to decrease fluid in the body and ease the strain on the heart. The prognosis of a patient with congestive heart failure depends on the stage of the heart failure and the overall condition of the individual.
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.
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.
Heart Disease: Sudden Cardiac Death
Second Source WebMD Medical Reference
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.
Second Source article from Government
Heart failure (congestive) is caused by many conditions including coronary artery disease, heart attack, cardiomyopathy, and conditions that overwork the heart. Symptoms of heart failure include congested lungs, fluid and water retention, dizziness, fatigue and weakness, and rapid or irregular heartbeats. There are two types of congestive heart failure, systolic or left-sided heart failure; and diastolic or right-sided heart failure. Treatment, prognosis, and life-expectancy for a person with congestive heart failure depends upon the stage of the disease.

Heart Attack vs. Heartburn (Differences between Symptoms and Signs)
Heartburn is a symptom of another disease or medical problem and can be described as a feeling of burning in the chest accompanied by symptoms of nausea, vomiting, or a sour taste or food stuck in the back of the throat. Heart attack occurs when an artery in the heart is completely blocked by a blood clot, which causes that portion of heart muscle to die. Heart attack also has symptoms of chest pain, nausea, and vomiting, however, other warning signs and symptoms of a heart attack are unusual weakness or fatigue, and persistent and/or increased severity of symptoms over a few minutes. Heart attack is a life threatening emergency. If you think you or someone you are with is having a heart attack, call 911 immediately for urgent medical treatment. It may save your life.
What Are the 4 Stages of Congestive Heart Failure?
The New York Heart Association developed the four stages of congestive heart failure depending on the functional capabilities of the heart which includes Class I, Class II, Class III, and Class IV.
Stress and Heart Disease
The connection between stress and heart disease is not clear. Stress itself may be a risk factor, or high levels of stress may make risk factors for heart disease worse. The warning signs of stress can be physical, mental, emotional, or behavioral. Reducing stressors in an individuals life not only can lead to a more productive life, but may also decrease the risk for heart disease and causes of heart disease.
Sudden Cardiac Arrest
Sudden cardiac arrest is an unexpected, sudden death caused by sudden cardiac arrest (loss of heart function). Causes and risk factors of sudden cardiac arrest include (not inclusive): abnormal heart rhythms (arrhythmias), previous heart attack, coronary artery disease, smoking, high cholesterol, Wolff-Parkinson-White Syndrome, ventricular tachycardia or ventricular fibrillation after a heart attack, congenital heart defects, history of fainting, heart failure, obesity, diabetes, and drug abuse. Treatment of sudden cardiac arrest is an emergency, and action must be taken immediately.
What Are the Four Signs of an Impending Heart Attack?
A heart attack occurs when the blood vessel that supplies blood to your heart (coronary artery) gets blocked – partially or completely. The lack of blood supply means the heart does not get enough oxygen or nutrients.
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 Attack vs. Stroke Symptoms, Differences, and Similarities
Heart attack usually is caused by a clot that stops blood flow supplying oxygen to an area of heart muscle, which results in heart muscle death. Stroke or "brain attack" is caused by a loss of blood supply to the brain (usually a blood clot) or by hemorrhagic stroke (bleeding within the brain), which results in brain tissue death. Both heart attack and stroke usually come on suddenly, produce similar symptoms, can be disabling, and can be fatal. The classic symptoms and warning signs of heart attack are different. Classic heart attack warning signs are chest pain or discomfort, shortness of breath, pain that radiates to the shoulders, back, arms, belly, jaw, or teeth, sweating, fainting, and nausea and vomiting. Moreover, woman having a heart attack may have additional symptoms like abdominal pain or discomfort, dizziness, clammy skin, and moderate to severe fatigue. The classic symptoms and warning signs that a person is having a stroke are confusion or loss of consciousness, sudden severe headache, speech problems, problems seeing out of one or both eyes, and numbness or weakness of only one side of the body. Moreover, a woman having a stroke may have additional warning symptom and signs like shortness of breath, disorientation, agitation, behavioral changes, weakness, nausea, vomiting, seizures, and hiccups. Recognition of stroke symptoms is vital for emergency treatment. The acronym "FAST" stands for recognition of Facial drooping, Arm weakness, Speech difficulty, and a Time for action. If you experience the symptoms heart attack or stroke (FAST) or see them develop in another person, then contact 911 immediately.
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.
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.
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).
Congenital Heart Defects
Congenital heart defects are heart problems that are present at birth. Genetics may play a role in some heart defects. Symptoms can range from nonexistent to severe and life-threatening. Fatigue, rapid breathing, and decreased blood circulation are a few possible symptoms of congenital heart defects. Many cases do not require any treatment. Procedures using catheters and surgery may be used to repair severe heart defects.
What Are the Signs of a Heart Attack in Women?
Many women think that the typical signs of a heart attack like crushing chest pain and shortness of breath can be easily recognized and cannot be missed. The 4 silent signs of a heart attack are fatigue, chest pain, pain in the upper back, shoulder, arms, neck or jaw, and sleep disturbances.
What Causes Congestive Heart Failure?
Congestive heart failure is a chronic disease that progresses with time if left untreated. Heart failure can occur due to diseases of the heart, the blood vessels supplying oxygen and nutrients to the heart, or sometimes from factors outside the heart (extracardiac causes). With proper management, people who have congestive heart failure can lead nearly normal lives, depending on the severity of the condition.
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.
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
Smoking and Heart Disease
Smoking increases the risk of heart disease in women and men. Nicotine in cigarettes decrease oxygen to the heart, increases blood pressure, blood clots, and damages coronary arteries. Learn how to quit smoking today, to prolong your life.
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 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.
What Is a Widowmaker Heart Attack?
A Widowmaker is a type of heart attack, which is deadlier than most others. A widowmaker heart attack occurs when the left ascending artery (LAD) that supplies blood to the front part of the heart (largest part) is clogged-up because of clots in the arterial wall. This causes the death of heart muscle in this area, medically termed myocardial infarction. Because the widowmaker damages a major portion of the heart, timely management is necessary to prevent fatalities.
