What is the difference between Left Ventricular Hypertrophy and Left Ventricular Dysfunction?
LVH (Left Ventricular Hypertrophy) is (anatomical) structural condition and status of the heart,
while Left Ventricular Dysfunction is disturbance in physiological functions and status of heart.
Why do people get heart disease?
some people get it because they have high cholesterol and some get because they smoke.
Who invented the defibrillator?
Bernard Lown is credited with the development of the external form of the defibrillator, a device to restart the heart muscle through the application of a low voltage shock across the heart, or externally across the chest. Lown developed the device based on US cardiologist Paul Zoll's emergency procedure that used simple AC wall current.
Alois A. Langer is credited as co-inventor of the implantable defibrillator. The actual development of the implantable ICD was pioneered at Sinai Hospital in Baltimore by a team including Michel Mirowski, Morton Mower, and William Staewen.
Defibrillation was first demonstrated in 1899 by Jean Louis Prevost and Frederic Batelli, two physiologists from University of Geneva, Switzerland. They discovered that small electric shocks could induce ventricular fibrillation in dogs, and that larger charges would reverse the condition.

How are electrostatics used in Defibrillators?
In order to stabilize the heart beat, defibrillators are used. It works by discharging electric charge with the help of two paddles that should used to provide electrical contact with the patient's chest through insulated handles that are heavily charged.
His life expectancy is around 2 years. If he changes his lifestyle and diet, he can live a lot longer.
How does propanolol treat cardiac ischemia?
Cardiac ischemia occurs as a result of insufficient blood flow to the coronary blood vessels.
This often occurs due the formation of plagues in the coronary arteries. These plagues narrow the interior of these blood flows resulting in less blood flow to the heart. Angina (or chest pain) sometimes occur as a symptom of cardiac ischemia.
The heart has the highest oxygen consumption per tissue mass when compared to other organs in the human body. Blood will flow to the heart during its diastole phase. The heart's vasomotor tone is often controlled by its endothelium where healthy endothelial cells will release nitric oxide to cause vasodilation to improve blood flow. However, endothelial cells which are damaged by plague cannot produce nitric oxide as efficiently so the presence of plagues will decrease vasodilation and this will hinder blood flow. Angina will occur when the oxygen supply does not meet the heart's demand.
Propanolol can be used to treat cardiac ischemia. It is a non-selective beta-blocker. It can limit the heart rate by limiting the release to catecolamines. The diastolic coronary perfusion time will hence increase and this is favorable for cardiac ischemia. It also decreases due excitability of the heart and hence reduces the myrocardial oxygen demand.
3 risk factors associated with infectious diseases?
Risk of CHIKV infection exists throughout the day, as the primary vector, Ae. aegypti, ... conditions, such as hypertension, diabetes, or heart disease, are likely risk factors for poor outcomes.
Does not having teeth cause heart disease?
No, not at all unless your gums are infected and there not taken care of. That can cause more than just Heart Disease. That can cause Lung Disease and Mouth Cancer aswell.
What does heart failure or congestive heart failure mean?
They do NOT mean that the heart stops, or that the persons suffering from them are near death. Often, these are conditions that can be treated. They mean, essentially, that the heart is for some reason weaker than it should be, and weak enough so that there is some fluid backup. The right heart takes systemic blood, blood from the body, and delivers it to the lungs so it can release carbon dioxide and pick up oxygen. If the right heart is failing, there may be edema, or swelling, in the arms or legs. The left heart brings blood that is freshly oxygenated by the lungs and delivers it to the body. If the left heart is weak, there may be congestion in the lungs from the fluid backup.
Why is coronary heart disease less common in some countries than in the US?
I believe that, during the German occupation of Norway in WW2, the incidence of coronary disease dropped dramatically due to the bulk of dairy products being compulsorily requisitioned by the Nazis and shipped back to Germany.
What is it called when you get short of breath and get dizzy?
It is called asphyxia.
These symptoms can be caused by many things. Usually these are signs of heart or lung problems, but many other conditions can also cause these to occur. So do not hesitate to have an examination to determine what is causing the symptoms you are having, so the right treatment can be started right away if needed.
Why is heart disease a chronic disease?
Chronic Heart Disease is a disease which mainly causes the deterioration of the heart and its functioning. Heart disease is a common disease which is spread across the world and has been estimated as a leaing cause of death in the unted states. Its also been deduced that lowering bad cholesterol levels and controlling pre-existing conditions such as hypertension could lower the possiblilty of chronic heart disease. When a patient is normally affected by chronic heart disease, it is important he seeks enough treatment and in some cases it can be an emergency. People with old age need regular screening for heart disease as this can ensure longevity of life. Hope this helps.
Chiang Kai Shek, the leader of the Chinese Nationalist Party, said this during the Second Sino-Japanese war. This quote means that the Japanese occupation is something minor that can easily be taken care of. The communists are the true problem. it is much harder to cure a heart disease, the communists, than it is to cure a skin disease, the Japanese occupying army.
What types of medical professionals assist in treatment of moyamoya disease?
medical professionals involved in the care of patients with moyamoya disease generally include specialists in neurology, neurosurgery, neuroradiology, and anesthesiology.
What is nutritional therapy for treating ischemia?
Nutritional therapy includes limiting intake of red meat and animal fats, eating a heart-wise diet, avoiding coffee, taking multivitamin/mineral supplement, natural supplements for health problems.
What is the prevalence of myocardial ischemia in the US?
According to the American Heart Association, up to four million Americans may have silent ischemia and be at high risk of having a heart attack with no warning.
Can you use an AED machine if some one has internal defibrillator?
You can, just make sure that the pads are about one inch away.
Do triglycerides cause heart disease?
In the human body, high levels of triglycerides in the bloodstream have been linked to atherosclerosis, and, by extension, the risk of heart disease and stroke.
What are the causes of silent ischemia?
Silent ischemia usually is caused by emotional or mental stress or by exertion, but there are no symptoms.
Are ischemic heart disease and atrial fibillation related?
No. These two are independent cardiac pathophysiologic phenomena.
Is pneumonia a lifestyle disease hereditary disease or infectious disease?
It is an infectious disease. However, you are more apt to get it if you smoke or have otherwise unhealthy lungs.
Is glomerular disease known as bright's disease?
Bright's Disease affects the kidney, including the nephrons and glomeruli. However, Bright's Disease is but one of many which affect the glomeruli of the kidney.
What are some diseases that occur in the heart?
- Coronary heart disease
- Cardiomyopathy
- Cardiovascular disease
- Ischemic heart disease

- Heart Cancer
Can I get medicare if I am 53 years old and have heart disease and Parkinson's?
If you are under 65, you can get Medicare Part A without having to pay premiums if you have:
- Received Social Security or Railroad Retirement Board disability benefits for 24 months.
- End-Stage Renal Disease and meet certain requirements.
While you don't have to pay a premium for Part A if you meet one of those conditions, you must pay for Part B if you want it. The Part B monthly premium in 2010 is $110.50.
If you have questions about your eligibility for Medicare Part A or Part B, or if you want to apply for Medicare, please contact Social Security or visit or call your local Social Security office. You can also get information about buying Part A as well as Part B if you don't qualify for premium-free Part A.
To get SSA disability, you must prove that your illnesses cannot be controlled or cured and that they make it impossible for you to do any sort of work for which you are suited based on your age, education and experience.
