Why the study?

Implication
Symptoms stratify progressive HF mortality and arrhythmias predict sudden death in dilated cardiomyopathy; hypothesis-generating for risk stratification pending prospective validation.
Structured PICO
Do heart failure symptoms and ventricular arrhythmia at initial assessment predict mortality in patients with dilated cardiomyopathy?
P
Population
124 patients with dilated cardiomyopathy
I
Intervention
Assessment of heart failure symptom severity and presence of ventricular arrhythmia
O
Outcome
Mortality from progressive heart failure and sudden deathhard clinical
Patients with dilated cardiomyopathy and mild symptoms generally have a benign clinical course, but the presence of occult ventricular arrhythmia significantly increases the risk of sudden death.
