The Profile of a Heart Attack

Heart attack is a popular term used by regular people to refer to what medical science specifically calls a myocardial infarction. It could also be used to denote any of several types of acute episodes of ischemic heart disease.

Ischemic heart disease is one of the most common causes of death in Western culture. It results from insufficient coronary blood flow, which means that the blood supply of your heart is cut off or severely impaired. Immediately after blocking the coronary arteries, blood flow beyond the occlusion is stopped. When this happens, the affected area is said to be infarcted and receives little to no blood flow. The cardiac muscle then suffers from oxygen and nutrient deprivation and is rendered incapable of sustaining normal cardiac function. The whole process is called a myocardial infarction.

What Causes Ischemic Heart Disease?

Ischemic heart disease can be caused by an increased demand of the body for oxygen or diminished oxygen blood transport. Most commonly, IHD is caused by a decrease in coronary blood flow due to narrowing or destruction of the walls of the coronary arteries as in atherosclerosis.

In atherosclerosis, there is an accumulation or formation of deposits of yellowish plaques called atheromas containing cholesterol, lipoid material, and lipophages in the walls of the arteries. These deposits cause the diameter of the artery to narrow as they accumulate until only little or no amount of blood flows through the lumen at all, causing ischemia or deprivation of the arteries.

Thyroid Function in Fat Metabolism

The thyroid gland, located just below the larynx or the voicebox, secretes two hormones called thyroxine or T4 and triiodothyronine or T3. These two hormones raise almost all aspects of fat metabolism in the body, especially T3. Lipids, especially, are mobilized from fat tissue rapidly so that fat stores in the body are depleted to a certain extent.

Thyroid hormones also facilitate the excretion of cholesterol through the bile. Increased amounts of thyroid hormones cause the cholesterol circulating in the plasma of the blood to be secreted into the bile, which can then be removed totally from the body when the bile is excreted through the feces.

Hypothyroidism and Atherosclerosis

Lack of thyroid hormone consequently raises the amount of cholesterol in the blood because fat and cholesterol metabolism is slowed down and there is a decreased rate in the secretion of cholesterol into the bile for excretion. Increase in blood cholesterol predisposes a person to atherosclerosis because the increased amount of cholesterol in the blood then forms plaques in arterial walls, the atheromas.

Hypothyroid patients usually develop atherosclerosis because of their decreased levels of thyroid hormone. This condition, in turn, could result in coronary artery disease, leading to heart attack, and possibly, early death.

Some people may be genetically predisposed to suffer a heart attack. For some, it is the kind of life they lead that could cause them to suffer a heart attack in the future. But with exercise and proper nutrition as well as a vigilant eye on all other aspects of health, heart attacks can be prevented from happening.

I’ve heard from several people that taking an Asprin while they were having a heart attack saved their lives, but they never told me how it helps save you..

Perhaps one of you can tell me the info. Thanks!

Sabretooth asked:


I believe that a heart attack means death of cardiac tissue.
I do not think that it has to mean to necrosis due to lack of oxygen, but could be due to other things such as electrical damage.

So an arrythmias attack that nearly kills someone that leads to perminant damage is a form of heart attack but not a ‘myocardial infarction’.

What is the odd of surviving one?

How long does symptoms last of someone who’s about to experience a heart attack, how long do they generally last?2 days ago My fiance had to hold his chest in such pain that radiated up his left arm & shoulder area as well,.then for the past 2 days has a very painful left side of jaw radiating down his neck? Are these common symptoms? If so would he have had one by now if there was one coming? Thank you for any relative info.

Coronary heart disease and its ensuing heart attacks have many risk factors identified by extensive research. Some of these factors are controllable, and some are not. The more risk factors you have, the greater your chances of suffering from a heart attack. Are you at risk? Below, read about five heart attack risk factors you can control.

Diabetes

Uncontrolled diabetes can lead to significant heart damage. If you have diabetes, make sure you eat a healthy diet, exercise regularly, and routinely take your medication prescribed by your doctor to control blood sugar levels.

Obesity/Physical inactivity

Get off the couch and move! A sedentary lifestyle lacking in sufficient exercise increases the chance for developing coronary heart disease. Regular exercise helps the heart and can also control obesity, blood cholesterol, and blood pressure, all of which add to your risk for having a heart attack. Studies have shown that high levels of body fat, especially around the waist, lead to an increased risk of developing heart disease. Extra weight increases the heart’s workload, so by losing as few as 10 pounds, you can lower your risk. Even just 30 minutes of exercise per day can be beneficial. Consult your doctor to ask about diet and exercise plans to help you reach a healthy weight.

Tobacco use

While stopping smoking is not easy, it is extremely important to your heart’s health, because cigarette smoking is a major cause of coronary heart disease. Indeed, smokers develop heart disease at two to four times the rate of nonsmokers. Cigarette smoking increases blood pressure and the blood’s tendency to clot and decreases good blood cholesterol. Exposure to other people’s tobacco smoke can also increase the risk, even in nonsmokers. More importantly, when smoking is combined with other factors, your chances of having a heart attack go up dramatically.

Psychosocial factors

Learning to control stress and the way you respond to it can be in important contributing factor to developing heart disease. Stress and anger may also influence other factors, because they may cause people to overeat, begin smoking or smoke more than usual, drink alcohol to excess, or turn to illegal drugs, all of which contribute to heart disease. While we all face stress in our daily lives, research shows that meditation, deep breathing exercises, massage, anger management, and other relaxation techniques can help you to better deal with those stresses.

High blood pressure and high cholesterol

High blood pressure overworks your heart, causing it to thicken and become stiffer. When combined with high blood cholesterol, obesity, smoking, or diabetes, the risk of heart attack increases. Animal fats (or saturated fats) found in red meat, dairy and fried foods can all contribute to high blood pressure and high cholesterol. Salt is another culprit. Look for healthier options. A low-sodium diet rich in fruits, vegetables, and grains along with medication can be useful in lowering high blood pressure and high blood cholesterol. Also, incorporating foods containing plant sterols (for example, cholesterol-lowering margarine) can also help to lower blood cholesterol.

Unfortunately, heart disease usually exhibits no symptoms before a heart attack occurs; therefore, preventive screening is extremely important. Mobile screening companies offer easy, non-invasive tests to identify your risk of heart disease through determining if you have developed peripheral arterial disease, which leaves you four to six times more likely to die from a heart attack. Mobile screenings, usually held in local gyms, churches, or community centers, are extremely convenient, usually only taking a few minutes out of your busy day, and they can save your life.

Barb Hicks - Clivir Team asked:


A study of 515 women who had an acute heart attack (MI, Myocardial Infarction), reported symptoms that were not your typical heart symptoms. The most commonly reported symptoms were unusual fatigue, sleep disturbances, shortness of breath, indigestion, and anxiety.

Only 30% of the women who reported chest pain had reports of aching and tightness.  Women who experience symptoms of heart disease tend to ignore or deny that any discomfort exists.  Women are less likely to seek help early when symptoms of heart disease begin to manifest themselves. They figure if they are feeling tired, its because the week must have been particular busy, let alone the fact that she may be having problems sleeping.  The most remote thing from her mind is that she could be on the road to an impending heart attack, thus is less prone to get needed medical attention. 

Statistics have shown that women have a higher risk for heart attack than men, due in part to changes in estrogen levels that take as she ages. Women who take birth control pills and smoke  are also at a higher risk.  In addition to this, as a woman ages, her risks for heart attack increase, and is more likely to succumb to heart disease.  Even if she suffers a heart attack while hospitalized, her chances of survival are less than that of a man.  Also, women tend to experience a cardiac event 10 years later than men do.  It is paramount for women to get educated and know their risks to prevent becoming a statistic.

Although a woman of any age can fall victim to a heart attack, having a family history of heart disease should be her first clue of what her risks involve.  Women need to realize that heart disease is their number one killer, and it is not just a disease of men. That is why its important for women to take charge of their health to know what her risks for heart disease are, and learn to recognize the signs and symptoms.

There are many options for treatment available, including the immediate opening of a blocked artery, restoring blood flow to the heart. Realizing the early symptoms of heart attack aids in the accuracy of the right diagnosis and the right treatment. Your health is your responsibility, so take care of yourself to ensure you live a healthy quality of life for as long as possible.

Jenny asked:


And angina pains?

I lost my husband due to a massive heart attack years ago, & I thought heart disease could be detected these days better than it was then.

I am somewhat of a band aid nurse, & I thought I knew some things about health, but I’ve learned lately due to a friend,that sometimes it masks itself & you cannot tell.

How can you tell if you have heart trouble? Is there anyone out there that has dealt with this? I thought that heart trouble was diagnosed easier than it was 10 years ago.

Thank you.
