This leads to heart failure. AAFP Feline Anesthesia Guidelines. The underlying cause of cardiomyopathy is only rarely treated, however if it develops secondary to taurine deficiency in the diet (which can be a cause of DCM), or secondary to conditions such as hypertension (high blood pressure) or hyperthyroidism (overactive thyroid gland), then treating the underlying disease may improve cardiac function. 54 Likes, 13 Comments - Residents (@lapmrresidency) on Instagram: “Resident’s Corner: Name: David Huy Blumeyer, MD Year in residency: PGY-4 Where were you born…” Hypertrophic cardiomyopathy: This is by far the most common form of cardiomyopathy.
