- It has been suggested that a genetic polymorphism in the angiotensin II type 1 receptor gene (ATRG) and the ACE gene DD genotype might have a synergistic influence on the risk of developing cardiovascular disease.To study the possible interaction between polymorphisms in the ACE gene and the ATRG, regarding survival and left ventricular function.Polymorphism of the two genes was studied in a population-based cohort of 194 patients with idiopathic heart failure, recruited from the western part of Sweden 1985-1988. The patients were investigated by echocardiography. The survival status was checked during the 7-year follow-up period.Although there was no statistically significant additive risk of the ATRG polymorphism, patients carrying the ACE gene DD genotype in combination with a C allele of the ATRG tended to have a poorer prognosis. DD +AA, OR 1.24 (95% CI 0.67-2.32, P = 0.49); DD +AC, OR 1.64 (95% CI 0.95-2.83, P = 0.08); DD + CC, OR 3.54 95% CI 0.78-16.1, P = 0.10); DD +AC/CC, OR 1.84 (95% CI 1.10-3.08, P = 0.02). Patients with the DD +AC/CC genotypes tended to have lower ejection fraction and increased left ventricular mass.There was a trend toward a worse prognosis in patients with the combination of a C-allele in the ATRG and the ACE gene DD genotype, suggesting an interaction of these two genetic polymorphisms on disease severity.

- AIMS: To get insight into the quality of life of a clinical practice sample of patients with heart failure that are admitted to the hospital. Secondly to determine differences between patients with systolic and diastolic dysfunction and finally to describe factors relating to quality of life. METHODS: Three dimensions of quality of life (functional capabilities, symptoms and psychosocial adjustment to illness) were assessed during interviews of 186 patients with chronic heart failure. In addition, data on demographic, clinical and self-care characteristics were collected and patients completed a 6-min walk. RESULTS: On average patients walked 172 m in 6 min and reported functioning in daily life at a mean level of 4.5 MET. Patients experienced four different symptoms of heart failure. Most of them described dyspnea, fatigue, sleep disturbance and ankle oedema. Problems with psychosocial adaptation occurred mostly in social and vocational domains. Overall well-being of patients was rated as 6.4 on a 10-point scale. In regard to quality of life, the only differences between patients with systolic and diastolic heart failure was the occurrence of ankle oedema and health-care orientation. The variance in components of quality of life were partly explained by demographics and clinical characteristics. All three dimensions of quality of life were related to ability for self-care. CONCLUSION: Patients with heart failure seen in clinical practice are often not comparable to patients described in major clinical trials or patients that are admitted for transplant evaluation. Their functional capabilities are more compromised, but they may have fewer problems with psychosocial adjustment. Patients with normal systolic dysfunction also report a low quality of life. It could be important to enhance self-care abilities of patients to improve psychosocial adaptation to illness.
