Comparative Study
Renin-angiotensin system and haemostasis gene polymorphisms and outcome after coronary artery bypass graft surgery.
Coronary artery bypass graft surgery is associated with a considerable 2-year mortality rate. Gene polymorphisms of the renin-angiotensin system may be associated with the risk of hypertension and cardiovascular disease. The angiotensin I-converting enzyme DD genotype has recently been identified as independent predictor of the outcome after coronary artery bypass graft surgery. Genetic factors of the clotting system may be related to the risk of myocardial infarction and restenosis after coronary interventions. The aims of the present study were to investigate whether gene polymorphisms of the renin-angiotensin system (angiotensinogen 235 M/T, angiotensin II type 1 receptor 1166 A/C) or the clotting system (glycoprotein IIIa PlA1/PlA2 and factor V Leiden 1691 G/A) are associated with the outcome after coronary artery bypass grafting. ⋯ We conclude that there are interactions between the angiotensin II type 1 receptor 1166 A/C as well as the angiotensinogen 235 M/T gene polymorphism and age with respect to the outcome after coronary artery bypass graft surgery. The glycoprotein IIIa PlA1/PlA2 and the factor V Leiden 1691 G/A gene polymorphisms were not associated with mid-term mortality or cardiac morbidity after coronary artery bypass grafting.

Comparative Study
Patient descriptions of breathlessness in heart failure.
To explore patient experience of breathlessness in heart failure. ⋯ Patients' descriptions of breathlessness are distinct from medical terminology and more clearly relate to physical adaptations to breathlessness. Further research is required to identify whether heart failure patients' descriptions of breathlessness are different to those of cancer patients, and to establish whether the categories generated from this data set are applicable to other heart failure patients in other settings.
