The three heart diseases I researched were chronic valvular disease, dilated cardiomyopathy, and heartworm. All three are life threatening and can be extremely fatal in canines. Chronic valvular disease is the most common heart disease in canines. It has an unknown cause and affects 20 to 40 percent of dogs. Smaller breeds of dogs are most affected. The disease is characterized by deteriorating changes in the heart valves. In most cases the mitral valve is affected. The tricuspid valve is affected in about one-third of cases. As one doctor writes, “The valve leaflets become thickened and distorted so that the free edges of the valves no longer make contact” (Dog Normal Heart Rate and Irregular Heartbeat). This can cause the cords that attach the valve leaflets to the lining of the heart to rupture, allowing the valve to flap in the bloodstream. These changes result in loss of valve function and a fall in cardiac output. The so called “trademark” of chronic valvular disease is a loud heart murmur, which can be heard over the left side of the chest. In most cases dogs with uncomplicated heart murmurs related to chronic valvular disease can remain symptom free for years. Treatment should be started at the first signs of heart failure. This includes coughing and becoming easily tired. Dilated cardiomyopathy is a disease of the heart muscle that reduces the pumping function of the heart. Symptoms usually include tiring, fainting, heart murmur, arrhythmias, and enlargement of the heart. As the heart becomes enlarged, its ability to pump blood out into the lungs and body deteriorates. This enlargement according to petmd.com “becomes overloaded, and this often leads to congestive heart failure.” Normally larger bred dogs are affected by dilated cardiomyopathy. The symptoms may be harder to notice in some dogs, especially older ones since they exercise less. For treatment “drugs may be administered to enhance heart contraction and to slow down rapid beating, and diuretics…
Heart Disease Risk Factors in Women
As a woman, heart disease is a real threat. Usually heart disease is seen as more of a men's issue, but in reality more women die each year than men. That is a fact that is quite astonishing, but real in today's world. A challenge that comes with this chronic disease is the symptoms vary between genders. Fortunately, steps can be taken to understand the unique symptoms and begin to reduce their risk of heart disease, and learn what the risk factors are.
A heart attack is the most common serious end-result of coronary heart disease, which is caused by blockages of the arteries that feed the heart. Heart attack is also the most common cause of death in both men and women in the U.S. Heart attacks are a major cause of disability and they frequently result in heart failure. In the coronary arteries is the most effective way to prevent heart attacks.
Compared to a typical man my age, my risk of having a heart attack is very much below average…

Who’s to blame for this out brake of death? Is it fast food, energy drinks, or maybe technology? Obesity is…
Cardiovascular disease is the highest known disease for causing mortality among Australia's population. It is also the second highest burden of disease (the first being cancer).
There are three major contributors to the overall burden of death in Australia, these being Coronary Heart Disease, Cerebrovascular Disease and Peripheral Vascular Disease.
The nature of cardiovascular Disease:
Cardiovascular disease affects all areas of the heart, with that being the heart, blood and blood vessels…

What is Ischemic Heart Disease?
Ischemic heart disease is caused by an imbalance between the myocardial blood flow and the metabolic demand of the myocardium. Reduction in coronary blood flow is related to progressive atherosclerosis with increasing occlusion of coronary arteries. Blood flow can be further decreased by superimposed events such as vasospasm, thrombosis, or circulatory changes leading to hypoperfusion. (Anversa and Sonnenblick, 1990)
Coronary artery perfusion depends upon the…
deficiency (VDD) has increased significantly in recent years, a change seemingly largely due to lack of sunlight exposure. The potential mechanisms by which VDD increases the prevalence of many forms of cardiovascular disease such as heart failure, hypertension and coronary artery disease have been determined and will be discussed further in this essay.
Vitamin D (VD) is mostly produced via UV radiation. UV rays with a wavelength between 290 and 315 nm are able to penetrate the skin and with the help…

1. Smoking Related Disease – Coronary Heart Disease
Coronary heart disease (CHD) is the leading disease causing death around the world through smoking cigarettes (due to the inhalation of 7,000 different poisonous chemicals). CHD is a term, which happens when a waxy substance called plaque builds up inside the coronary arteries. These arteries, supply oxygen-rich blood to your heart muscle. This wax is a mixture fatty deposit…
