Review Meta Analysis
Low-dose aspirin for secondary cardiovascular prevention - cardiovascular risks after its perioperative withdrawal versus bleeding risks with its continuation - review and meta-analysis.
Low-dose aspirin given for secondary prevention of cardiovascular disease is frequently withdrawn prior to surgical or diagnostic procedures to reduce bleeding complications. This may expose patients to increased cardiovascular morbidity and mortality. Aim of the study was to review and quantify cardiovascular risks because of periprocedural aspirin withdrawal and bleeding risks with the continuation of aspirin. ⋯ Only if low-dose aspirin may cause bleeding risks with increased mortality or sequels comparable with the observed cardiovascular risks after aspirin withdrawal, it should be discontinued prior to an intended operation or procedure. Controlled clinical studies are urgently needed.

We evaluated the predictive value of chills, bacteraemia and endotoxaemia for in-hospital mortality and survival at 5-10 years long-term follow-up in a prospective cohort of 'early sepsis' patients presenting with fever resulting from community-acquired pneumonia or pyelonephritis. Febrile patients with chills had bacteraemia more often (RR 3.1, 95% CI 1.8-5.4) than those without chills. ⋯ Patients with chills had a significantly higher survival rate at long-term follow-up than those without chills on admission: the estimated risk of dying was 0.644 (95% CI 0.43-0.95, P = 0.029) for an individual with chills, compared to a person without chills, adjusting for the other factors [age cohort, underlying disease and the pro-inflammatory response in the blood, i.e. tumour necrosis factor-alpha (TNF-alpha) and blood leucocyte number, as scored on hospital admission] in the Cox proportional hazards model. Chills may characterize a patient subpopulation that upon pulmonary and urinary tract infection is able to raise a more rapid and/or efficient host response.

Hypertensive patients with metabolic syndrome (MS) are at greater risk for cardiovascular disease. To get a better understanding of the pathophysiology underlying this association, we evaluated the relationship between MS and subclinical organ damage in essential hypertensive patients. ⋯ Metabolic syndrome is associated with subclinical organ damage in nondiabetic, essential hypertensive patients. These data may, in part, explain the high cardiovascular morbidity and mortality that is observed in hypertensive patients with MS.
