Acute Lower Respiratory Tract Infection Increased the Risk of Cardiovascular Events and All-Cause Mortality in Elderly Patients With Stable Coronary Artery Disease.

ABSTRACT: Objective: To investigate the predictors of acute cardiovascular events within 90 days after an acute lower respiratory tract infection (ALRTI) in elderly patients with stable coronary artery disease (sCAD). Methods: Observational analyses were conducted in a prospective cohort of the elderly with sCAD, during 90 days after they were hospitalized for ALRTI. Multiple logistic regression analysis was performed to identify predictors for acute cardiovascular events and all-cause mortality. Results: The present study comprised 426 patients with sCAD (median age: 88 years; IQR: 84-91; range: 72-102). Among these patients, 257 suffering from ALRTI were enrolled in the infection group. Meanwhile, 169 patients who did not suffer from ALRTI were regarded as the non-infection group. Compared with the non-infection group, patients in the infection group had a higher incidence of acute cardiovascular events (31.9 vs. 13.6%, p < 0.001) and all-cause mortality (13.2 vs. 1.8%, p < 0.001) during the 90-day follow-up. In addition, in the infection group, the incidence of cardiovascular events was also higher than those in the non-infection group during the 7-day and 30-day follow-up (10.9 vs. 2.4%, p = 0.001; 20.6 vs. 6.5%, p < 0.001). The same difference in the incidence of all-cause mortality during 7 and 30 days (1.2 vs. 0%, p = 0.028; 3.9 vs. 0.6%, p = 0.021) was observed between the two groups. Furthermore, multiple regression analysis found that ALRTI was independently associated with increased risk of cardiovascular events and all-cause mortality in elderly patients with sCAD. Conclusion: In elderly patients with sCAD, ALRTI was an independent predictor for both cardiovascular events and all-cause mortality.

Project description:BackgroundGrowth differentiation factor 15 (GDF-15) has been explored as a potential biomarker for various inflammatory diseases and cardiovascular events. This study aimed to assess the predictive role of GDF-15 levels in cardiovascular events and all-cause mortality, considering traditional risk factors and other biomarkers.MethodsA prospective study was conducted and 3699 patients with stable coronary artery disease (CAD) were enrolled into the research. Baseline GDF-15 levels were measured. Median follow-up was 3.1 years during the study. We analyzed clinical variables and several biomarkers. Multivariable Cox regression analysis was performed to evaluate prognostic performance of GDF-15 levels in predicting myocardial infarction (MI), heart failure, stroke, cardiovascular death, and non-cardiovascular death.ResultsBaseline GDF-15 levels for 3699 patients were grouped by quartile (≤ 1153, 1153-1888, 1888-3043, > 3043 ng/L). Higher GDF-15 levels were associated with older age, male gender, history of hypertension, and elevated levels of N-terminal pro B-type natriuretic peptide (NT-pro BNP), soluble suppression of tumorigenesis-2 (sST2), and creatine (each with P < 0.001). Adjusting for established risk factors and biomarkers in Cox proportional hazards models, a 1 standard deviation (SD) increase in GDF-15 was associated with elevated risk of clinical events [hazard ratio (HR) = 2.18, 95% confidence interval (CI): (1.52-3.11)], including: MI [HR = 2.83 95% CI: (1.03-7.74)], heart failure [HR = 2.71 95% CI: (1.18-6.23)], cardiovascular and non-cardiovascular death [HR = 2.48, 95% CI (1.49-4.11)] during the median follow up of 3.1 years.ConclusionsHigher levels of GDF-15 consistently provides prognostic information for cardiovascular events and all cause death, independent of clinical risk factors and other biomarkers. GDF-15 could be considered as a valuable addition to future risk prediction model in secondary prevention for predicting clinical events in patient with stable CAD.

Project description:IntroductionThere are limited data on cerebrovascular events in patients with stable coronary artery disease. To study the risk of cerebrovascular event, the relative proportion of ischaemic stroke and intracranial haemorrhage, and their prognostic factors in stable coronary artery disease are investigated.Patients and methodsThe CORONOR registry prospectively recruited, between February 2010 and April 2011, 4184 unselected stable coronary artery disease outpatients. All events occurring during a five-year follow-up were adjudicated.ResultsNinety-six patients had an ischaemic stroke and 34 had an intracranial haemorrhage, reaching a cumulative incidence after five years of 3.2 (2.7-3.8)%. During the same period, 677 deaths and 170 myocardial infarctions (ST-elevation MI, n = 55; non-ST-elevation MI, n = 115) occurred. In elderly individuals, the number of cerebrovascular events was higher than that of myocardial infarctions and largely exceeded that of ST-elevation myocardial infarctions. Predictors of ischaemic stroke were: previous history of stroke (subhazard ratio (SHR)=3.16(1.95-5.14)), absence of statin therapy at inclusion (SHR = 2.45(1.47-4.10), increasing age (SHR = 1.45(1.16-1.82) per 10-year increase) and diabetes mellitus (SHR = 1.65(1.10-2.49)). Predictors of intracranial haemorrhage were: combination of vitamin K antagonists with an antiplatelet agent at inclusion (SHR = 5.41(2.49-11.75), single antiplatelet therapy as reference), and increasing age (SHR = 1.47(1.12-1.93) per 10-year increase).DiscussionIn stable coronary artery disease patients, the brain deserves attention. In patients at high risk of ischaemic stroke, secondary prevention could be intensified. Our results raise awareness of the hazard of the association of antiplatelet drugs with oral anticoagulants in stable coronary artery disease patients.ConclusionWhile improving the prevention of future vaso-occlusive events should be our ultimate goal in coronary artery disease patients, the net clinical benefit of our treatments should carefully be studied.
