Ray La Foy asked:


It’s considered one of the biggest killers in the United States. In fact, an estimated 13.2 million Americans suffer from coronary heart disease. With a number sufferers that rivals the population of some small countries, this disease is serious business. But, what is it and how can it be detected and prevented? When it comes to coronary heart disease, CHD for short, knowledge and action are key. Prevention isn’t always possible, but steps can be taken.

Coronary heart disease is a condition that results from the creation of plaques along the walls of the coronary arteries. This essentially impacts blood flow to the heart. The process is call atherosclerosis. If the condition continues, the heart can become deprived of oxygen, which weakens it and may even lead to the “death” of certain parts of the heart. This, of course, means a heart attack, which can be fatal.

Here are some facts about the disease and its impacts:

* The condition is the biggest cause of death for men and women in the United States. It’s estimated nearly 500,000 people die each year from this most ravaging of conditions.

* The United States alone records about 1.2 million heart attacks a year. Doing the math shows just under half the cases die, which is unacceptable in any book.

* The sad but true fact about coronary heart disease is that in many cases the condition was preventable. Risk factors, for the most part, involve lifestyle choices - with a few exceptions.

The risk factors of coronary heart disease are many, but keep in mind, most are personal choices. They include:

* High blood pressure, which can be medically or stress caused.

* High cholesterol

* Smoking

* Obesity

* Physical inactivity. When the heart doesn’t get a work out, the whole body can pay eventually.

* Diabetes

* Stress

The key to preventing CHD is to recognize its risk factors and take steps to eliminate them or at least lessen them in a person’s life. While not all things that cause CHD can be removed, doing things such as quitting smoking, eating right and adding exercise to a routine can very much lessen the chances of problems down the road.

Detecting CHD in a person involves an invasive test called an angiography. While the condition’s presence can be guessed at otherwise, and in most cases a guess is accurate, the angiography is required for a definitive diagnosis. An invasive procedure, this test involves the insertion of a tube into the artery that releases a dye. A picture is then taken with the dye helping to highlight blocked areas. The test can be done during an inpatient hospital stay or even at an outpatient facility.

While the best treatment for CHD is total prevention, that won’t do the trick every time. Surgery is available and many times those on the path for having a heart attack can change course in time to avoid disaster. Eating right, exercising and not smoking are key to avoiding the disease as is following doctor’s orders.

CHD is the biggest killer in the United States. Its prevention is possible, but people have to be willing to stay the course. There are ways to avoid the tragedy that is a heart attack, but it’s up to the individual to ensure success.

My husband attended a hospital with intermittant chest pain. After an ECG that was borderline and showed the above abnormalities and a BP reading of 210/120. He was sent away with a diagnosis of digestive/gallstone problems but asked to visit his GP for BP checks. he died 5 days later from heart failure due to heart disease. Should the ECG, if done properly shown up more?

Verlyn Ross asked:


Ischemia is not a familiar term to many. This article is an attempt to explain it and to clarify it.

Ischemia is a form of coronary heart disease that occurs when fat deposits and plaque serve to narrow the interior of an artery to such a severe point that the heart is not able to receive enough oxygen-rich blood for its purposes and is therefore deprived. In as simple terms as possible, ischemia is a restriction in blood supply. What ends up happening is the heart muscle cramps. In this way then, ischemia that takes place in the heart is very much like getting a severe cramp in your leg, only cramping of the heart is more serious than cramping that occurs in the leg area.

Ischemia usually takes place when the heart is in need of an extra supply of oxygen. This is most likely to take place when there is a great deal of physical activity or exertion such as during weight training or practically any form of exercise, when a person is eating, when an individual is either very excited or under a great deal of stress and when a person is exposed to extreme temperatures, such as the very cold. Coronary artery disease can become so severe that ischemia can begin to take place even when a person is in a resting state.

Sometimes ischemia can be relieved quickly and easily and other times, or for some individuals it takes much longer. When it can be dealt with and gotten out of the way in a reasonably speedy span of time, such as within a 10 minute period with the help of either bed rest or medicine then it is sometimes given the name “stable coronary heart disease” or in other cases simply called, “stable angina.”

When blood vessels are blocked or become constricted due to ischemia what takes place is angina pectoris. This condition can occur for a number of reasons. It can take place as a result of tachycardia, which is an abnormally fast heartbeat, or due to thromboembolism, which are blood clots. Angina pectoris can also take place due to atherosclerosis, which is defined as “lipid-laden plaques obstructing the lumen of arteries”, and hypotension, which is the technical name for low blood pressure, which is likely to occur in cases of heart failure or septic shock.

But there are still other reasons why angina pectoris in relation to ischemia could take place. A tumor could cause outside compression or pressure on a blood vessel, which could bring about the problem. There could be foreign bodies in existence that could cause the problem, such as in the case of a pregnant woman, amniotic fluid that is in evidence within an amniotic fluid embolism. Finally angina pectoris could also occur as a result of sickle cell disease, which constitutes hemoglobin that is shaped abnormally.

Due to the fact that oxygen is connected to hemoglobin in all red blood cells, when there is an inadequate flow of blood the tissue then becomes hypoxic and in extreme cases, with no oxygen supply whatsoever, it becomes anoxic. A state of anoxic can lead to the death of cells, which is known as necrosis. When necrosis occurs as a result of ischemic it generally takes anywhere from 10 to 12 hours to occur.

Andrew Bicknell asked:


Heart disease is the number one cause of disease caused death in the United States today. The latest statistics show that of the 2.4 million people who die every year in the U.S. 36 percent of them died of some form of heart or cardiovascular disease. For many people heart disease sneaks up on them unawares and causes an unforeseen heart attack. Simply recognizing the symptoms of heart disease before a major medical emergency and seeking help can help reduce the risk of a life threatening event.

So what are the heart disease symptoms you should be on the lookout for and what should you do if you start to experience them? The short answer to the second part of that question is to see your doctor immediately. The sooner any form of this deadly condition is diagnosed and treated the better your chances of living a long and healthy life.

Here are the symptoms everyone should be conscious of. And remember, each one taken by itself should indicate a potential problem but if there are combinations of these symptoms the greater the risk.

1. Angina - This refers to chest pain, one of the major warning signs of a heart attack. Any chest pain needs to be checked out by a doctor as soon as possible. The problem with angina is that many people with heart disease may not experience it until they are actually having a heart attack and by then it may be too late.

2. Numbness and Tingling - If you experience these symptoms particularly of the face or arms and it is localized to one particular side it could be a warning sign of blocked or damaged arteries. If slurred speech, headache, and loss of coordination or balance is also experienced you should seek immediate medical attention.

3. Shortness of Breath - Problems with the respiratory system can be a symptom of any number of problems, one of which is heart disease. If it is a continual problem then you need to seek medical attention.

4. Dizziness or Fainting - Having dizzy or fainting spells when you normally haven’t experienced them in the past are both signs of possible cardiovascular disease. This is true if you start to get these symptoms after exercise or other physical activities. These types of symptoms are common in heart valve disease and manifest as positional vertigo which are symptoms occurring upon standing from a lying or sitting position. These include dizziness, brief loss of eye sight, and ringing in the ears.

5. Fatigue and Weakness - It is normal to feel somewhat tired at the end of a long day at work. If this worsens in intensity over time it could be an indication of some sort of heart problem.

Heart disease is a very serious condition that if not diagnosed and treated in an aggressive manner can quickly have deadly consequences. Fully understanding and recognizing the symptoms of heart disease is the first step to seeking medical attention to help stop this silent killer in its tracks.

Kristin asked:


He finds the best-fit (regression) line for predicting deaths from heart disease (in deaths per 100,000 population) from the amount of wine consumed (in liters per person per year). The line is given by:
Heart disease death rate = 168.5 – 1.5 x wine consumption
The doctor reckons that by increasing the wine consumption rate to 115 liters per year, the country will eliminate all deaths from heart disease. Give two reasons why this conclusion may not be valid.

James Hunt asked:


Heart disease is the main cause of death for women, causing four out of every ten deaths. If you are a woman you are eight times more likely to die from heart disease and stroke than from breast cancer. More women pass away from heart disease than from all types of cancer combined. Roughly as many women die from heart disease and stroke each year as men.

• Women may be more likely to experience uncharacteristic warning signs such as indistinct chest discomfort • Some risk factors such as hormones and diabetes can considerably add to the risk of heart attack amongst women. • Some diagnostic tests and treatments for heart attack may not work as well on women. • In the past, heart disease among women was not treated as aggressively as men and fewer women were referred for treatments such as bypass surgery and balloon angioplasty following a heart attack.

Recognize the warning signs and take action fast!

Learn the indication of heart disease. Learn the signs of heart attack. They are different.

Early warning signs of heart disease in women include:

• Pain or discomfort in the chest that comes on with physical activity and goes away with rest • Shortness of breath, breathlessness, or unusual tiredness with physical activity • Physical activities that used to be easy or normal have become difficult

If you experience any of these feelings, seek medical advice.

Warning signs of heart attack in women

• Vague chest tightness, discomfort, pain or a crushing radiating chest pain • Heaviness, pressure, squeezing, fullness, burning or pain that may begin in the center of the chest and spread to the neck, jaws, and shoulder • Unusual pain that spreads down one or both arms • Shortness of breath, paleness, sweating or weakness • Nausea, vomiting and/or indigestion • Feelings of extreme anxiety, fear and/or denial

If you experience any of these feelings, tell someone right away or call for emergency help.
