For women with less than a high school diploma, in 2008, 15 percent of that group was childless; in 1994, that figure was 9 percent.

Drugs, such as Nexium, Prilosec, and Prevacid, that are supposed to treat frequent heartburn could be increasing people's risk of hip, spine, and wrist fractures. These drugs will change the way their body absorbs calcium that leads to less-dense bones, which can increase the risk of fractures.

One of the first signs of diabetes is bleeding gums or bone loss around the teeth.

Diabetes occurs when the body is unable to produce or unable to properly use and store glucose (a form of sugar). It is a major risk factor for heart disease. People who are over 40 and overweight are more likely to develop diabetes.

Diabetes is the 7th leading cause of death in the U.S. for people aged 25 years and older; 23.6 million people in US have diabetes; 11.2% of men and 10.2% of women have diabetes.

Eating brown rice can cut diabetes risk.

One in 10 Chinese adults already have diabetes; the finding surpasses other Western nations, including Germany and Canada.

Stroke is the number three killer in the US, affecting almost 800,000 people each year. Top risks for a stroke include high-fat diet, being single, being unhappy, being obese, smoking, and being born in the wrong demographic.

Zocor can cause muscle damage as well as severe and potentially lethal kidney damage.

There are three types of muscles in the human body: cardiac, smooth and skeletal. Cardiac muscle makes up the wall of the heart. Smooth muscles make up the walls of the intestine, the uterus, blood vessels, and internal muscles of the eye. Skeletal muscles are attached to the bones; contraction of the skeletal muscles helps limbs and other body parts move.

The hardest working muscle is the heart. It pumps out 2 ounces (71 grams) of blood at every heartbeat. Daily the heart pumps at least 2,500 gallons (9,450 liters) of blood. The heart has the ability to beat over 3 billion times in a person’s life.

Lack of sleep causes fat accumulation around organs.

Men with insomnia (i.e.; sleeplessness) who sleep fewer than six hours each night are at an increased risk of dying compared with people who sleep longer. Less sleep has also been linked with hypertension and other risk factors for cardiovascular disease.

Having high blood pressure (HBP) and coronary artery disease (CAD) puts you at a greater risk of a heart attack or stroke. You can have HBP for years without knowing it because HBP itself usually has no symptoms. If your blood pressure rises and stays high over time, it can damage your heart, blood vessels, kidneys, and other parts of your body. The numbers in a blood pressure reading include Systolic and Diastolic. Systolic (the top number) is the maximum pressure in the arteries when the heart is contracting or squeezing. Diastolic (the bottom number) represents the pressure in the arteries when the heart is at rest. The recommended blood pressure goal is below 140/90 mmHg (millimeters of mercury). If your blood pressure is above that level, you may have HBP. The most common of medications to treat HBP in people who have CAD is Beta-blockers, which slow the heart rate, reduce the heart's output of blood, and decrease the force of the heart beat.

Cardiovascular disease (CDV) is responsible for 35.3 percent of all deaths in the U.S. Today, the chance of dying in few days immediately after of a heart attack is around 6 percent. CDV deaths declined by 26.4 percent from 1995 to 2005. In 1994, it was about 10 percent. In 1984, it was 19 percent. In the 1960s, it was 30 to 40 percent.

Sugar intake linked to heart disease - Just like eating a high-fat diet can increase your levels of triglycerides and high cholesterol, eating sugar can also affect those same lipids.

One of major factors caused the cardiovascular disease is higher levels of cholesterol and triglycerides. Cholesterol and triglycerides are necessary for our life. While cholesterol is essential for body to work properly, triglycerides provide the fuel needed for body cells to function. Total cholesterol (TC) is an estimated measure bad cholesterol (LDL), good cholesterol (HDL) and triglycerides. TC = LDL + HDL + (Triglycerides/5). Goal: less than 200 mg/DL for TC. LDL, or bad cholesterol, carried cholesterol to tissues in your body. Higher levels of LDL in your blood mean that cholesterol is being stick to your artery walls. The arteries may develop a fatty buildup called atherosclerosis. Goal: less than 100 mg/dL for LDL. HDL, or good cholesterol, carried cholesterol away tissues in your body. Higher levels of HDL in your blood mean that cholesterol is being carried away from artery walls to the liver and then eliminated from the body. Goal: greater than 60 mg/dL for HDL. Triglycerides are another fatty substance in the blood. Higher levels of triglycerides in your blood mean larger thickening of the artery walls, which causes higher risk of stroke, heart attack and heart disease. Goal: less than 150 mg/dL for Triglycerides. Some commonly prescribed medications lowering your cholesterol are: Crestor, Lescol, Lipitor, Pravachol and Zocor.

As per American Heart Association, 1,314,000 angioplasties, in which a plastic catheter is snaked into the blocked artery and a small balloon is inflated, opening the vessel, were done in the United States in 2006. Of these 1,313,000 were percutaneous coronary interventions (PCIs).  855,000 men and 459,000 women had angioplasties. 448,000 cardiac revascularizations (also known as coronary artery bypass graft or CABG operations) were done in the United States in 2006. CABG was performed on 323,000 men and 125,000 women. In 2007, American cardiologists performed 721,000 angioplasties. Patients were often given out of the hospital a year of clopidogrel (Plavix) and a life time of stain, ACE inhibitor, beta blockers and aspirin. The cost of a heart attack treatment was about $5,700 in 1977 to $54,400 in 2007.

A new study raises fresh concerns about Zetia and its cousin, Vytorin. Zetia failed to shrink buildups in artery walls, and Zetia users also suffered more heart attacks. Vytorin is a pill that combines Zetia with a statin. it has been proven that neither Vytorin nor Zetia are any better at lowering cholesterol, reducing plaque buildup in the arteries, or prevent heart attacks or death than low grade niacin.

Heart disease is the number one killer of American of all ages while cancer is the number one killer of Americans under 85. 46% of women and 22% of men heart attack survivors will be disabled with heart failure within six years. 435,000 American women have heart attacks annually; 42% die within 1 year; which kill six times as many women as breast cancer.

If you've ever been hospitalized, do not make any decisions before you have received, and analyzed, all the bills. Once you've determined what you can afford, ask the hospital's credit officer for interest-free payments. If the debt is truly unwieldy, ask for the Medicare rate (not the insurance rate) or a charity write-off.
