Do heart attacks skip a generation?

User Avatar

Asked by Wiki User

While gallbladder disease may have genetic components, it does not keep track of the last generation affected. It can "skip" a generation or affect the children of affected patients.

Why is heart disease the number one killer in the US?

User Avatar

Asked by Wiki User

i think cardiovascular diseases are common in the United States because of all the junk food that we eat and the lack of exersise. Many Americans would rather watch T.V than exersise.

Can a bicuspid aortic valve cause a heart attack?

User Avatar

Asked by Wiki User

Yes, a bicuspid aortic valve can be repaired if it is diseased. The procedure usually involves a small incision and the valve will either be repaired, or more often, replaced with a synthetic valve.

How does the congenital Heart disease disease progress over time?

Asked by Wiki User

The pathologic, physiologic, or biochemical mechanism results in the development of congenital heart disease. Congenital conditions exist at birth and may be hereditary or may occur during gestation up to the moment of birth.

What is the ICD-9 code for Congestive Heart Failure?

User Avatar

Asked by Wiki User

The ICD-9 code for left ventricular dysfunction is 429.9. Left ventricular dysfunction can lead to heart failure. Some signs include increased rate of breathing and increased work of breathing. You may hear wheezing also.

What is the science behind the invention of the portable defibrillator?

User Avatar

Asked by Wiki User

The defibrillator was invented by William B. Kouwenhoven in 1930. He studied the relation between the electric shocks and its effects on human heart and tested it on a dog. In 1947 Dr. Carl Beck tested the technique on a human patient and saved his life.

How can emphysema and congestive heart failure can lead to acid base imbalance?

User Avatar

Asked by Wiki User

I am too assume you are asking imbalances because normally the body balances acid-base

This is a very complex process.

there are four main types of acid-base imbalance in the body.

Respiratory Acidosis (Low pH)

Metabolic Acidosis (Low pH)

Respiratory Alkalosis (High pH)

Metabolic Alkalosis (High pH)

Respiratory means that the imbalance is caused by the lungs

Metabolic means that the imbalance is caused by the cells in your body

In emphysema {or a form of chronic(long-term) obstructive(blocking) pulmonary(involves the lungs) disease(abnormal condition in body) or COPD}

the lungs cannot properly remove CO2

(oxygen is breathed in, used by cells in your body and the cells release carbon dioxide or CO2 as waste which is breathed out)

Emphysema(COPD) is the destruction of the elastic tissue in the thousands of little are sacs in the lungs. Because the sacs can no longer push the CO2 out of the lungs the CO2 gets trapped and builds up.

when CO2 builds up short term it will caused increased breathing rate (CO2 tells your brain to breath faster when it builds up)

when CO2 builds up long term the blood will compensate through chemically changing the CO2 into other chemicals

CO2 + H2O <--> H2CO3 <--> HCO3- + H+ (equilibrium equation)

Once the CO2 Builds up long term it will cause the above chemical equation to change the CO2 eventually into HCO3- and H+ .

H+ will increase in the blood as more and more carbon dioxide is converted.

pH simply measures the amount of H+ ions in an exponential numbering system

the more the H the lower the number (i know its the opposite of what you would think)

When the pH gets low (or H ions in the blood gets to high) this can cause

Respiratory Acidosis (lung/breathing caused acidic blood)

the body can only operate in a narrow pH range of 7.35-7.45

If the blood goes above or below it can cause serious trouble and eventually put someone into a coma or cause death

people with COPD develop increased CO2 over such a long period of time that the body will slowly become use to the high CO2 in the lungs but the person would still be at risk for this type of imbalance.

Because CO2 tells your brain to make you breath faster (not a lack of oxygen)

people with COPD experience the need to breath faster especially when moving around a lot or exercising more frequently. NEVER EVER should a COPD or emphysema patient receive more than 2L/min (Metric) of oxygen while on oxygen therapy. Increasing the oxygen in the lungs will force CO2 out but this could cause the brain to say "well there is less CO2 so i don't need to breath as much" and this could cause a person's breathing to slow so much that they may stop breathing all together.

What are the causes of congestive heart failure in a patient?

User Avatar

Asked by Wiki User

Coronary artery disease and high blood pressure are the main risk factors for congestive heart failure.

How does coronary heart disease affect the cells?

User Avatar

Asked by Wiki User

All the cell of your body are affected by heart disease. The cells of the body need the oxygen and nutrients carried by blood in order to survive. The heart pumps blood. If the heart is unable to adequately pump blood, the cells do not get what they need in order to survive, and will eventually die. Heart disease can be managed by your health care provider, and there are means to make the heart pump better in order to prolong the life of the cells that we need so much to survive.

How is heart disease related to unbalanced diet?

User Avatar

Asked by Wiki User

Staying healthy is not just a matter of getting exercise or taking vitamins. It can also involve the foods we eat. A person who wants to have a healthy heart should avoid smoking; as for what to eat, a heart-healthy diet has fruits and vegetables and lean meats in it. It does not have much junk food in it-- eating too much fatty or high-calorie foods, as well as eating a lot of fried foods, can be very bad for the health of your heart, and can lead to clogging of your arteries.

What are three ways to make healthful choices to help avoid heart disease in the future?

User Avatar

Asked by Wiki User

Three ways to make healthful choices would be to think before you drink; the best thing is plain water the worst is a soda, or even worse alcohol. Second would be think before you eat; the best is fresh natural unprocessed whole food and the worst is anything and everything that is deep fried. Third way would be to think before you lay down; the best thing would be that you did some exercise during the day and the worst would be if the last time you got up and did anything was the day before. If that's the case, promise yourself that you will do better tomorrow. Then, do your best to keep your promise. You see, changing habits is not really as easy as it sounds, just ask anyone that has tried to do that by making too many changes in a short period of time. That is a recipe for frustration and failure. Be patient with yourself and take small steps, one at a time, and after a while you will be surprised at how much progress you've made.
