OBJECTIVES:: To understand the disease and treatment patterns of Chronic Heart Failure (CHF) in Mexico. METHODS:: A Disease Specific Program was conducted to assess the impact of CHF. Patient record forms (PRF) were completed by 50 cardiologists for 8 consecutive patients with CHF. The same patients were invited to complete a patient self-completion questionnaire. RESULTS: The PRF (n=394) data revealed that a typical CHF patient was male (62%) with a mean age of 64.8 years. Physicians reported a shorter duration of time that patients experienced symptoms before visiting a doctor; reporting 36 weeks, versus the patient-reported 39.8 weeks. Patients on average had been diagnosed for two years and the majority (66%) were considered to be stable/compensated. Cause: Hypertension was the leading cause of CHF (58%), followed by CHD/Myocardial infarction (33%). Physical signs/examinations were used to diagnose and monitor CHF; the key tests were blood pressure and heart rate. For 54% (n=211) of patients, the primary reason for consultation was diagnosis and/or testing of CHF symptoms. The lower a patient’s ejection fraction, and the more severe the NYHA functional classification, the more unstable/decompensated the patient was considered to be. Hospitalization: In the last year, 42% of patients were hospitalized for CHF, 7% of which were readmitted to hospital within 30 days (n=8). Physicians believed that half of patients were at a moderate or greater risk of being hospitalised and/or dying in the next year. Treatment: 75% of doctors and patients were in agreement about how the last treatment decision was made. Nearly 70% of patients received a Beta Blocker; 55% received Loop Diuretics, 52% received Statins, and 51% were prescribed ACE (angiotensin-converting-enzyme) inhibitors. Physicians reported that only 5% of patients took OTC (over-the-counter) CHF treatment. CONCLUSIONS:: These data are important for better understanding treatment patterns and characteristics of CHF in Mexico.
