Long-term prognostic value of quantitative myocardial perfusion in patients with chest pain and normal coronary arteries.

Background: Patients with chest pain and no obstructive coronary artery disease have shown a high incidence of major adverse cardiovascular events (MACE). We evaluated the role of absolute myocardial perfusion quantification in predicting all-cause mortality and MACE during long-term follow-up in this group of patients.

Methods: We studied 79 patients who underwent Nitrogen-13 ammonia PET for quantification of global myocardial blood flow (MBF) and myocardial flow reserve (MFR) due to suspected impaired myocardial perfusion.

Patients undergoing elective coronary artery bypass grafting exhibit poor pre-operative intakes of fruit, vegetables, dietary fibre, fish and vitamin D.

CHD may ensue from chronic systemic low-grade inflammation. Diet is a modifiable risk factor for both, and its optimisation may reduce post-operative mortality, atrial fibrillation and cognitive decline. In the present study, we investigated the usual dietary intakes of patients undergoing elective coronary artery bypass grafting (CABG), emphasising on food groups and nutrients with putative roles in the inflammatory/anti-inflammatory balance.

BNP and NT-proBNP, predictors of 1-year mortality in nursing home residents.

Objectives: To investigate 1-year mortality prediction of B type natriuretic peptide (BNP) and N terminal-proBNP (NT-proBNP) in institutionalized elderly with multiple morbidities.

Design: Prospective cross-sectional study.

Setting: One nursing home.

Prevalence and misdiagnosis of chronic heart failure in nursing home residents: the role of B-type natriuretic peptides.

Background/objectives: Without knowing the exact CHF prevalence, chronic heart failure (CHF) occurs frequently in elderly people both inside and outside nursing homes. For a diagnosis we have to rely on physical examination and additional tests. We therefore run the risk of missing CHF diagnoses or of diagnosing CHF when we should not.
