Why the study?

Congestive heart failure is a leading cause of canine deaths in India, but lack of advanced diagnostic facilities often results in delayed diagnoses.

Population

Aged dogs with congestive heart failure and 251 other screened dogs in India

Comparison

Aged dogs with congestive heart failure vs other screened dogs

Implication

Diagnostic gaps delay canine CHF care in India; leaves open whether expanded testing improves outcomes.

Structured PICO

P
Population
275 geriatric dogs in India, screened out of 2,574 registered cases. Includes 24 dogs diagnosed with congestive heart failure (CHF) due to dilated cardiomyopathy (n=9), mitral valve disease (n=7), hypertrophic cardiomyopathy (n=3), and pericardial effusion (n=5), as well as 251 other screened dogs and 17 control dogs.
I
Intervention
12-lead electrocardiography (ECG) screening
C
Comparator
Healthy control dogs (n=17) and non-CHF screened dogs (n=251)
O
Outcome
Prevalence and types of electrocardiographic abnormalities (arrhythmias and morphological changes)surrogate

Routine ECG screening in geriatric dogs reveals a high prevalence of arrhythmias, with atrial fibrillation and low QRS amplitude being the most common findings in those with congestive heart failure.
