The incidence of heart failure is rising rapidly, and it is currently the most common cardiovascular disease. Approximately 20–40% of patients with heart failure have preserved left ventricular systolic function, and an impairment of ventricular relaxation is considered the primary cause. There is controversy surrounding the definition of diastolic dysfunction and the diagnostic criteria for diastolic heart failure. Moreover, there are few studies on therapy for diastolic heart failure, which makes the management of these patients a real challenge.
Key words: heart failure, treatment, diagnosis, diastolic dysfunction.
