Heart swells in the dog
Heart failure - a pathological condition characterized by the inability of the heart to provide normal blood circulation. It is observed more often in old and large dogs.
Causes and development of the disease
The reasons are very diverse: heart defects, myocarditis, pericarditis, myocardial infarction, cardiomyopathy, cardiosclerosis, arterial hypertension, etc.
Heart failure leads to worseningblood supply to organs, stagnation, which ultimately causes pathological changes in the myocardium. A vicious circle is created, when deterioration of the heart leads, in the final analysis, to a further deterioration in the functioning of the heart muscle.
Depend on the cause of heart failure.
Congestive left ventricular failure due to mitral malformations is characterized by elevated pressures in the pulmonary veins and manifested by shortness of breath, pulmonary rales, tachycardia.
Left ventricular failure of ejectiondue to stenosis of the aorta, arterial hypertension, weakness of the left ventricle is characterized by a decrease in cardiac output and is manifested by fainting, shortness of breath, and tachycardia. A deadly consequence of left ventricular failure is pulmonary edema, often found in parvoviral enteritis.
Congestive right ventricular failuredue to the defects of the tricuspid valve, exudative pericarditis is characterized by high venous pressure and is manifested by swelling of the jugular veins, enlargement of the liver, swelling of the subcutaneous, extremities, ascites, oliguria.
Right ventricular failure of ejectiondue to stenosis of the pulmonary artery, pulmonary hypertension, weakness of the right ventricle is characterized by worsening circulation of blood in a small circle of circulation and manifested by dyspnoea.
The diagnosis is not difficult to base onclinical signs. The dog is languid, it is tired. When the load increases, shortness of breath, tachycardia. Dry and wet rales are heard in the lungs. There are edemas of limbs and a podgotko, ascites. Often the heart increases in volume. It is necessary to differentiate from pneumonia (fever), cirrhosis, renal failure.
Limit physical activity to a minimum.
Prescribe lifelong cardiac glycosides (see "Cardiomyopathy dilating"), however, with arrhythmias, it is necessary to reduce the dose or cancel the drug. To improve metabolism in the myocardium prescribe potassium preparations, vitamin preparations, quarantil. With edema, ascites and the threat of pulmonary edema - furosemide (lasix), spironolactone, ureitis. With cachexia - retabolil or phenobolin intramuscularly once a week, hepatoprotectors. In the case of acute heart failure, subcutaneously, a solution of camphor, caffeine, intramuscular cordiamine, sulfocamphocaine.
Prevention should be aimed at preventing the underlying disease.
