Congestive Heart Failure
A damaged or overworked heart muscle is unable to keep blood circulating normally Damage to the heart muscle may result from rheumatic fever, pneumonia, heart attack, or other cardiovascular problems. Diuretics relieve fluid accumulation
steroids
Anabolic steroids are artificial forms of the male hormone testosterone. They include ergogenic drugs, which are substances that enhance athletic performance. There are two forms of anabolic steroids: Injectable solutions Pills Effects of steroids include mood swings, acne, liver tumors, elevated cholesterol levels, hypertension, and kidney disease.
key cardiovascular diseases
Atherosclerosis is a disease in which fatty substances, cholesterol, cellular waste produces, calcium, and fibrin build up within arteries and clog them. Hyperlipidemia is a key factor in its development. Coronary heart disease (CHD) kills 16 percent of all Americans. It includes new and recurrent heart attacks as well as silent heart attacks. Myocardial infarction, a heart attack, is caused by an area of the heart that suffers permanent damage due to a reduced supply of blood. The blockage causing this is a coronary thrombosis. If the thrombosis moves, it becomes an embolus. Stroke, also known as a cerebrovascular accident, occurs when the blood supply to the brain is interrupted. Ischemic strokes are caused by plaque formation or a clot; a hemorrhagic stroke is caused by a weakening of the blood vessel that causes it to bulge or rupture. An aneurysm is a life-threatening hemorrhagic stroke. A transient ischemic attack (TIA) is a brief interruption of blood flow to the brain. It usually precedes a stroke by days, weeks, or months. Hypertension-sustained high blood pressure-is an asymptomatic disease affecting one third of Americans. Systolic pressure measures the working pressure of the heart when it contracts. Diastolic pressure measures the amount of pressure maintained in the arteries during the heart's relaxation period. Angina pectoris is pressure or squeezing in the chest or pain in the shoulders, arms, neck, jaw, or even back. Arrhythmia is an irregularity in heart rhythm that may result in symptoms such as cardiac fluttering, palpitations, or racing. Fibrillation is a sporadic, quivering type of heartbeat, whereas can be fatal. Tachycardia is an abnormally fast heartbeat, bradycardia, an abnormally slow one. Congestive heart failure (CHF) is a progressive, incurable disease in which the heart becomes weak and unable to keep the blood circulating. CHF responds well to treatment. Congenital cardiovascular defects—about 36,000 children are born with congenital cardiovascular defects each year.
surgical options: bypass surgery, angioplasty, and stents
Coronary bypass surgery takes a blood vessel from another site and implants it to bypass blocked arteries and transport blood. Angioplasty involves threading a thin catheter through the blocked arteries Following angioplasty, some people have a stent inserted to hold the blood vessel open. A stent is a stainless steel mesh-like tube that is inserted to prop open the artery

What is tar?
1. Tar is condensed particulate matter from smoke that accumulates in the lungs. In its condensate form, tar is a sticky brown substance that is the main cause of lung and throat cancer in smokers. 2. Tobacco smoke contains hundreds of damaging chemical substances. Smoke from an unfiltered cigarette contains 5 billion particles per cubic millimeter, or 50,000 times more than in an equal amount of polluted urban air. When condensed, these particles form a sticky mass called tar.

What is a stroke?
A stroke occurs when the blood supply to the brain is interrupted. A thrombus is a stationary blood clot. An embolus is a free-flowing clot. An aneurysm is a bulging or burst blood vessel. A transient ischemic attack (TIA) is a brief interruption of the blood supply that causes temporary impairment. This may be felt as a sudden numbness or weakness in the face or in an arm or leg, especially on one side of the body.
Atherosclerosis/ Coronary Artery Disease
Atherosclerosis is characterized by deposits of fatty substances, cholesterol, cellular waste products, calcium, and fibrin in the inner lining of the artery. Arteriosclerosis, or thickening and hardening of the arteries, is a type of atherosclerosis. It underlies many cardiovascular health problems and is believed to be the biggest contributor to disease burden globally. Hyperlipidemia: an abnormally high blood lipid level Plaque is formed by fatty deposits inside the vessels. Sclerosis is hardening of the vessels.

diagnosing, treating, and recovering from cardiovascular disease
Techniques for diagnosing heart disease: -Electrocardiogram (ECG): a record of the heart's electrical activity Angiography: aka cardiac catheterization, is more accurate than ac ECG. A needle-thin tub called a catheter is threaded through heart arteries, a dye is injected and an X ray is taken to discover blockages. Positron emission tomography (PET): produces 3D images of the heart as blood flows through it. During a PET scan, a patient, both at rest and during exercise, receives an intravenous injection of a radioactive tracer. Magnetic resonance imaging (MRI): uses power magnets to look inside the body. Computer generated pictures can show the heart muscle and help identify problems Ultrafast computed tomography (CT): fast form of heart xray designed to evaluate bypass grafts, diagnose ventricular function and measure calcium deposits Cardiac Calcium score:

The Facts Benzodiazepines are sedative-hypnotics. Rohypnol is the "date rape" drug. How Users Feel Low doses reduce or relieve tension but may cause rapid mood changes, impaired judgment, and impaired social and occupational functioning. High doses produce slurred speech, drowsiness, and stupor. Side Effects Physical and psychological dependence within 2 to 4 weeks Cross-tolerance is a complication Mood and behavior changes, slurred speech, poor coordination, unsteady gait, involuntary eye movements, impaired attention or memory, and stupor and coma Synergistic effect when used in combination with alcohol Gamma hydroxybutyrate (GBH) is a CNS depressant known to have euphoric, sedative, and anabolic effects.
