Signs and Symptoms
Methods of Diagnosis
Coronary just means of the heart .
Generally all disease causes cardiac heart failure:
What does heart failure? It is a situation in which the heart is shown “insufficient” to perform the functions that characterize it, ie providing adequate blood supply to the various organs of the body. Many disease of the heart can lead is in advanced stages of heart failure.
Compensatory mechanisms that activates the body allow patients with heart failure remain symptom or manifestation s clinic for months or years.
Heart failure is a disease severe with high rates of mortality a few years of its evolution.
2. The symptom s of heart failure are mainly due to congestion of the pulmonary vessels and decreased blood flow to the heart propels. Compensatory mechanisms that activates the body, as we said, they allowed our pet has not submitted symptom s over a certain period of time, but then there will be the gradual emergence of symptom s, begin to notice that your dog or cat has decreased to exercise tolerance and cough, the degree of renal evolves gradually, progressively limiting their normal development, reaching box coughing even at rest (mostly at night), ascites (collection of fluid in the abdominal cavity), hydrothorax, syncope etc …. Heart failure is a disease severe, with high rates of mortality a few years of its evolution. The main symptom is breathlessness called dyspnea. Dyspnea is the symptom of heart failure key, in fact, according to the degree of dyspnea that this is extrapolated, in part, the degree of heart dysfunction.
Generalizing and educational purposes only we group the heart s more common in veterinary medicine in the following groups:
* Cardipatía valve
* Heart s gongénitas
* Filaria: Worm Heart
This is called the disease of the heart muscle itself is, come in both dogs and cats (more frequent in canine s). In this group of disease is the cardiac muscle which is affected, leading to failure of the contraction thereof and hence heart failure because the heart is unable to beat properly.
Generally disease is chronic s, insidious and slow progression.
The etiology (cause) may be primary (unknown: idiopathic) or secondary to other disease is systemic or metabolic (endocrine, nutritional, toxic, disease is infectious, tumors).
It is the most prevalent and clinically significant of all disease is heart primarily affects small breed dogs-old poodle, cocker, maltese, yorkshire terrier, chihuahuas-, are more likely to suffer from degenerative valve s heart, although it can occur in any breed of dog of six years and older or cat (less often). The incidence is higher in males than in females (1.5: 1).
The valve of the heart s act as “gates” that allow the passage of blood from a heart chamber to the other. Typically, these “gates” close perfectly well, so that blood does not “return” to the compartment above and cause blood congestion there. When the valve s heart these processes suffer from degenerative closing capacity thereof is altered, favoring the return blood and become congested at any of the valve s heart. This anomaly is causing the heart begins to dilate in one or more of their cameras, secondarily altering the contractility of the heart muscle. All this leads to heart failure, which if not diagnosed and treated in time can lead to death.
they are not always the cause degenerative, there are some situations where it is inflamed or infected these important valve s heart. Whether you do not close properly, allowing leakage, or not open at all obstructing the flow of blood, the heart suffers a lot, and quickly pays little heart failure appears.
Heart Congenital Heart Failure
In the latter group includes “manufacturing defects” of the heart, with some dogs and cats are born, cardiovascular malformations that result from an abnormality in embryonic development. Are rare, but when they appear likely to develop congestive heart failure of rapid evolution. The most common, and in this order, are: patent ductus arteriosus, 4th persistent right aortic arch, the stenosis and pulmonary stenosis aortic. Less common are atrial and ventricular septal defects, tetralogy of Fallot, and all others are very rare.
Overall, alterations congenital heart s produce several pathology s: The outcome, of course, alterations in cardiac congenital s is bad , especially if you have congestive heart failure. The prognosis is good when it is the case of a patent ductus arteriosus and surgery is performed very quickly and has not developed congestive heart failure (CHF).
