RISK FACTORS

                            Certain factors contribute to the unwanted bluidup of fatty deposits (atherosclerosis) that narrows arteries throughout your body. You can improve or eliminate many of these risk factors to reduce your chances of having a first or another heart attack.

Heart attack Risk Factors include:

       
 • Age. Men age 45 or older and women age 55 or older are more likely to have a heart attack than a younger men and women.

• Tobacco. This includes smoking and long-term exposure to secondhand smoke.

• High blood pressure. Over time high blood pressure can damage arteries that feed your heart. High blood pressure that occurs with other conditions, such as obesity, high cholesterol or diabetes, increases your risk even more.

•High blood cholesterol or triglyceride levels. A high level of low-density lipoprotein(LDL) cholesterol (the "bad" cholesterol) is most likely to narrow arteries. A high level of triglycerides, a type of blood fat related to your diet, also ups your risk of heart attack. However a high level of high-density lipoprotein (HDL) cholesterol (the "good" cholesterol) lowers your risk of heart attack.

• Obesity. Obesity is associated with high blood cholesterol levels, high triglyceride levels, high blood pressure and diabetes. Losing just 10 percent of your body weight can lower this risk, however.

• Diabetes. Not producing enough of a hormone secreted by your pancreas (insulin) or not responding to insulin properly causes your body's blood sugar levels to rise, increasing your risk of heart attack.

• Metabolic syndrome. This occurs when you have obesity, high blood pressure and high blood sugar. Having metabolic syndrome makes you twice as likely to develop heart disease than if you don't have it.

• Family history of heart attack. If your siblings, parents or grandparents have had early heart attacks (by age 55 for male relatives and by age of 65 for female relatives), you might be at increased risk.

• Lack of physical activity. Being inactive contributes to high blood cholesterol levels and obesity. People who exercise regularly have better cardiovascular fitness, including lower high blood pressure.

• Stress. You might respond to stress in ways that can increase your risk of a heart attack.

• Illicit drug use. Using stimulant drugs, such as cocaine or amphetamines, can trigger a spasm of your coronary arteries that can cause a heart attack.

• A history of preeclampsia. This condition causes high blood pressure during pregnancy and increases the lifetime risk of heart disease.

• An autoimmune condition. Having a condition such as rheumatoid arthritis or lupus can increase your risk of heart attack.

MI (HEART ATTACK)

Image
                           A heart attack happens when the flow of oxygen-rich blood to a section of heart muscle suddenly becomes blocked and the heart can't get oxygen. If blood flow isn't restored quickly, the section of heart muscle begins to die. Overview: Heart attacks most often occur as a result of, also called ischemic heart disease, coronary heart disease or coronary artery disease. Ischemic heart disease is a condition in which a waxy substance called plaque builds up inside the coronary arteries. These arteries supply oxygen-rich blood to your heart. When plaque builds up in the arteries, the condition is called atherosclerosis. The buildup of plaque occurs over many years. Eventually, an area of plaque can rupture (break open) inside of an artery. This causes a blood clot to form on the plaque's surface. If the clot becomes large enough, it can mostly or completely block blood flow through a cor...

DIAGNOSIS

Image
Ideally, your doctor should screen you during regular physical exams for risk factors that can lead to a heart attack. If you're in an emergency setting for symptoms of a heart attack, you'll be asked about your symptoms and have your blood pressure, pulse and temperature checked. You'll be hooked up to a heart monitor and have tests to see if you're having a heart attack. Test include: • Electrocardiogram (ECG): This first test done to diagnose a heart attack records the electric activity of your heart via electrodes attached to your skin. Impulses are recorded as waves displayed on a monitor or printed on paper. Because injured heart muscle doesn't conduct electrical impulses normally, the ECG may show that a heart attack has occured or is in progress.                      • Blood tests: Certain heart proteins slowly leak into your blood after heart damage from a heart attack. Emergency room doctors will take samples ...

The Gut- Brain Connection

The gut-brain axis is actually quite fascinating in its complex interplay among several systems within the body, which communicate bidirectionally from the gut to the brain, thereby influencing mood, cognition, and even behavior—that is how integrated physical and mental health could be. We delve deep in this chapter into the underlying mechanisms, key players, and implications of this connection. 1. Gut-Brain Axis: A Communication Network The gut-brain axis has been defined as the major system allowing exchange of information between the gut and the brain. It reflects cross-talks between the CNS and ENS, this latter sometimes said to be the "second brain" because it autonomously governs gut functions. Sometimes, these two systems communicate with a mix of nerves, hormones, immune pathways, and neurotransmitters: Vagus Nerve : This is the longest cranial nerve directly connecting the brain stem to the digestive tract. It is considered to play a major role in the transmission ...
