Atherosclerosis & Stroke

Atherosclerosis is often referred to as “hardening of the arteries.” .It’s the process in which fatty substances, cholesterol, cellular waste products, calcium and other substances build up in the inner lining of an artery. This buildup is called plaque.

Atherosclerosis is a slow, complex disease that typically starts in childhood and often progresses when people grow older. This disease progresses rapidly in some people in their 20s. In others, it doesn’t become a threat until they’ve reached their 50s or 60s.

Atherosclerosis & Stroke

Causes of atherosclerosis

People with a family history of premature cardiovascular disease have an increased risk of atherosclerosis. Other risk factors for atherosclerosis include:

Cigarette smoking

Cigarette smoking and exposure to tobacco smoke (the chemicals in cigarettes can cause damage to blood vessels accelerating the development of atherosclerosis)

High blood cholesterol

High blood pressure

The inner lining of the artery, called the endothelium, can be damaged due to high cholesterol and triglyceride levels, toxic substances in cigarette smoke, high sugar levels, and other factors in the blood. High blood pressure can also cause damage to the inner lining of an artery. Once the blood vessel is damaged, atherosclerosis begins and a plaque forms.

the endothelium

the progress of the condition

Because of the damage, fats, cholesterol, platelets, cellular debris and calcium begin to deposit in the artery walls. These substances may stimulate the cells of the artery wall to produce still other materials. This results in more cells accumulating in the innermost layer of the artery wall where the atherosclerotic lesions form. These cells accumulate, and many divide. At the same time, fat builds up within and around these cells. They also form connective tissue. This buildup is called plaque. It usually affects large and medium-sized arteries. These cells and surrounding material thicken the endothelium significantly. The artery’s diameter shrinks and blood flow decreases, reducing oxygen supply.

How atherosclerotic plaque causes damage?

Plaques that rupture cause the formation of blood clots that can block blood flow or break off and travel to another part of the body. In either of these cases, if a clot blocks a blood vessel that feeds the heart, it causes a heart attack. If it blocks a blood vessel that feeds the brain, it causes a stroke. If blood supply to the arms or legs is reduced or blocked, it can cause difficulty walking and eventually gangrene.

Stroke and atherosclerosis

There are two types of ischemic stroke caused by blood clots, narrowing of blood vessels to the brain caused by atherosclerosis or other particles. Atherothrombotic stroke is the most common stroke. It occurs when a blood clot forms on a atherosclerotic plaque within a blood vessel in the brain and blocks blood flow to that part of the brain.

Stroke and atherosclerosis

Cerebral embolism occurs when a wandering clot or some other particle, called an embolus, is carried by the bloodstream until it lodges in an artery leading to or in the brain and blocks the flow of blood. The embolism could be due to a piece of clot or plaque that broke off from an atherosclerotic plaque. However, most embolic strokes are due to blood clots that form during atrial fibrillation and enter the bloodstream.

Ischemic

The kind of stroke caused by a clot is called an ischemic stroke, and is by far the most common type, accounting for 87 percent of all cases.

Hemorrhagic

A hemorrhagic stroke is the kind where a weakened blood vessel bursts and bleeds into the brain, compressing the surrounding brain tissue. This kind accounts for about 13 percent of stroke cases.

Transient ischemic attack (TIA)

The third kind of stroke, known as mini stroke or transient ischemic attack (TIA), is caused by a temporary clot. This type should more rightly be called a warning stroke because while they may last only a minute or two, they’re a major wake-up call to start making some lifestyle changes and consult your doctor ASAP.

signs of stroke demand immediate attention, even if it seems like the worst possible timing.



Due to a family history or other risk factors, even a woman who has always thought of herself as perfectly healthy can find herself suddenly experiencing the symptoms of stroke.

What is a stroke

A stroke happens when either a blood vessel that carries oxygen and nutrients to the brain is blocked by a clot or the vessel bursts. When either of these occur, the brain does not receive the oxygen-rich blood it needs and brain cells begin to die, and quickly. That’s why it’s so important to know the signs and symptoms of stroke.

Heart Disease and Diabetes in Women

Your body gets most of its energy from glucose, a form of sugar that comes from some of the food you eat. If you have diabetes, it’s harder for your body to turn food into energy. That’s because the body either:

Heart Disease and Diabetes in Women

cannot produce enough insulin (a hormone produced by the pancreas),

or both.

cannot use insulin (also called insulin resistance),

heart disease treatment in women and in men

Without enough insulin, glucose can’t enter the cells. Over time, the amount of glucose in your blood rises and cells are starved of energy. In addition to heart attack and stroke, uncontrolled diabetes can eventually lead to other health problems as well, such as blindness, kidney failure, and amputations.

Heart disease & diabetes often occur together. Whether you have heart disease or are at high risk of it, get your blood glucose (sugar) level checked regularly, especially if diabetes runs in your family.

Diabetes

Heart Disease and Diabetes in Women
  • 10.6 million women have diabetes (8 percent of all women ages 20 years and older)
  • 3 million women who have diabetes are undiagnosed.
  • 34.4 million women have pre-diabetes.
  • 14.6% of African-American women have diabetes.
  • 11.8% of Hispanic-American women have diabetes.
  • Prevalence for diabetes African American women is two times higher than in Caucasian women (14.6% of African-American women have diabetes while 6.1% of Caucasian women have diabetes)

Heart Disease

Heart Disease in Women
  • 43.8 million women are currently living with some form of cardiovascular disease. Nearly 7 million women have a history of heart attack and/or angina.
  • 6.6 million women are currently living with coronary heart disease (CHD).
  • Heart disease is the leading cause of death of American women and is responsible for 1 in 3 deaths in women annually.

  • Diabetes dramatically increases a woman’s chances of developing heart disease and having a heart attack and at much younger ages.
  • Diabetes erases the heart protective benefits of estrogen during child-bearing years.

Women with diabetes are up to five times more likely to develop heart disease than women who don’t have diabetes.

Women with diabetes are up to five times more likely to develop heart disease than women who don’t have diabetes. Women with diabetes who have survived a heart attack are at much greater risk of having a second one compared to women without diabetes. Diabetes contributes to heart-related deaths.

Two out of three women with diabetes die from heart disease.

While the death rate from heart disease has dropped by 27 percent in women without diabetes, deaths from heart and blood vessel disease in women with diabetes have increased by 23 percent over the last 30 years.

Smoking doubles the risk for heart disease in people with diabetes.
