Atrial fibrillation after pulmonary lobectomy for lung cancer affects long-term survival in a prospective single-center study.

Background: Atrial fibrillation (AF) after thoracic surgery is a continuing source of morbidity and mortality. The effect of postoperative AF on long-term survival however has not been studied. Our aim was to evaluate the impact of AF on early outcome and on survival > 5 years after pulmonary lobectomy for lung cancer.

Changes in plasma lipids during renin-angiotensin system blockade by combination therapy (enalapril plus valsartan) in patients with diabetes and hypertension.

There is experimental evidence of an interaction between the angiotensin system and lipid metabolism. The aim of this study was to evaluate whether a block of the angiotensin system achieved both by ACE inhibition and angiotensin II-AT1 receptor blockade could affect the plasma lipid profile and, if so, what relationship exists between these possible changes and glucose metabolism and blood pressure. In 50 patients with type 2 diabetes and hypertension, treated with diabetes drugs and enalapril, we evaluated the glycemic and lipid profile together with the HOMA insulin-resistance index, blood pressure and microalbuminuria at baseline and 3 months after the addition of valsartan.
