Cardiovascular insufficiencies
Heart failure is the inability of the circulatory system to supply the tissues with the amount of blood they need at all times. This disability may be due to a heart failure or failure of the heart to receive enough blood. This problem can be caused by pathologies such as the following:
- Dilated cardiomyopathy: This happens when the heart has trouble contracting properly, making systole and diastole difficult. It causes the muscular walls of the heart to thin and the atria and ventricles to enlarge. This causes an enlargement of the heart that cannot provide the body with enough oxygen, consequently producing periods of fatigue and suffocation. It is usually treated with diuretics, pimobendan and IEAS, all to reduce edema, to improve the contractility of the heart and as vasodilators.
- Valvular degeneration: This problem falls on the heart valves, which do not work properly, causing blood to back up into the atria. Consequently, as in dilated cardiomyopathy, it causes the heart to enlarge. It is treated using ACE inhibitors and diuretics.
Any type of heart failure can cause the dog to drown due to the lack of oxygen that this produces. In this link we tell you more about How to know if my dog has heart problems.
