Hyperuricemia is a Risk Factor for One-Year Overall Survival in Elderly Female Patients with Acute Coronary Syndrome.

ABSTRACT: Background:Hyperuricemia is a risk factor for cardiovascular diseases, but the impact of hyperuricemia and sex-related disparities is not fully clear in elderly patients with acute coronary syndrome (ACS). Objective:To investigate the association between hyperuricemia and 1-year all-cause mortality in elderly patients with ACS. Methods:This retrospective cohort study included 711 consecutive ACS patients aged ?75 years, hospitalized in our center between January 2013 and December 2017. Serum uric acid (sUA), in-hospital events, and 1-year follow-up were analyzed. Multivariable logistic regression models were used to explore the risk factors for in-hospital events and 1-year all-cause mortality. Results:sUA levels were higher in males than in females (381.4?±?110.1 vs. 349.3?±?119.1??mol/l, P < 0.001). Prevalence of hypertension (80.5% vs. 72.6%, P < 0.001). Prevalence of hypertension (80.5% vs. 72.6%, P < 0.001). Prevalence of hypertension (80.5% vs. 72.6%, P < 0.001). Prevalence of hypertension (80.5% vs. 72.6%, P < 0.001). Prevalence of hypertension (80.5% vs. 72.6%, P < 0.001). Prevalence of hypertension (80.5% vs. 72.6%, P < 0.001). Prevalence of hypertension (80.5% vs. 72.6%, P < 0.001). Prevalence of hypertension (80.5% vs. 72.6%, P < 0.001). Prevalence of hypertension (80.5% vs. 72.6%.

Project description:OBJECTIVE: To investigate comorbid conditions with prognostic influence in non-ST-segment elevation acute coronary syndrome (NSTEACS). PATIENTS AND METHODS: The study group consisted of a derivation cohort of 1017 patients (admitted from October 1, 2002, through October 1, 2008) and an external validation cohort of 652 patients (admitted from February 1, 2006, through September 30, 2009). Comorbid conditions, including risk factors and components of the Charlson comorbidity index (ChCI) and coronary artery disease-specific index, were recorded. The main outcome was one-year mortality. RESULTS: During follow-up, 103 patients died. After adjusting for variables associated with NSTEACS characteristics (base model), 5 comorbid conditions predicted mortality: severe or mild renal failure (hazard ratio [HR], 2.9 and HR, 1.6, respectively), dementia (HR, 3.1), peripheral artery disease (HR, 2.0), previous heart failure (HR, 2.6), and previous myocardial infarction (HR, 1.4). A simple comorbidity index (SCI) was developed using these variables, (per point: HR, 1.6; 95% confidence interval, 1.4-1.8; P = .0001). Adding the SCI, Charlson comorbidity index, or coronary artery disease-specific index to the base model resulted in a gain of 6.58%, 5.00%, and 4.04%, respectively, in discriminative ability (P = .001), without significant differences among the 3 indices. In patients with comorbid conditions, the highest risk period was in the first weeks after NSTEACS. The strength of the association between SCI and mortality rate was similar in the external validation cohort (HR, 1.3; 95% confidence interval, 1.1-1.6; P = .001). CONCLUSION: Renal dysfunction, dementia, peripheral artery disease, previous heart failure, and previous myocardial infarction are the comorbid conditions that predict mortality in NSTEACS. A simple index using these variables proved to be as accurate as the more complex comorbidity indices for risk stratification. In-hospital management of patients with comorbid conditions merits further investigation.

Project description:BACKGROUND: Despite advances in pharmacologic therapy and invasive management strategies for patients with non-ST-segment elevation acute coronary syndromes (NSTE ACS), these patients still suffer substantial morbidity and mortality. OBJECTIVE: The objective of this study was to analyze independent predictors of 1-year mortality in patients with high-risk NSTE ACS. DESIGN AND PARTICIPANTS: A total of 9,978 patients were assigned to receive enoxaparin or unfractionated heparin (UFH) in this prospective, randomized, open-label, international trial. MEASUREMENTS: Vital status at 1 year was collected. Univariable and multivariable predictors of 1-year mortality were identified. Three different multivariable regression models were constructed to identify: (1) predictors of 30-day mortality; (2) predictors of 1-year mortality; (3) predictors of 1-year mortality in 30-day survivors. The last model is the focus of this paper. RESULTS: Overall, 9,922 (99.4%) of patients had 1-year follow-up. Of the 56 patients (37 UFH-assigned and 19 enoxaparin-assigned) without 1-year data, 11 patients were excluded because of withdrawal of consent, and 45 could not be located. One-year mortality was 7.5% (7.7% enoxaparin-assigned patients; 7.3% UFH-assigned patients; P = 0.4). In patients surviving 30 days after enrollment, independent predictors of 1-year mortality included factors known at baseline such as increased age, male sex, decreased weight, having ever smoked, decreased creatinine clearance, ST-segment depression, history of diabetes, history of angina, congestive heart failure, coronary artery bypass grafting, increased heart rate, rales, increased hematocrit, lowered hemoglobin, and higher platelet count. Factors predictive of mortality during the hospitalization and 30-day follow-up period were decreased weight at 30 days from baseline, atrial fibrillation, decreased nadir platelet, no use of beta-blockers and statins up to 30 days, and not receiving an intervention (c-index = 0.82). CONCLUSIONS: Easily determined baseline clinical characteristics can be used to predict 1-year mortality with reasonable discriminative power. These models corroborate prior work in a contemporary aggressively managed population. A model to predict 1-year mortality in patients surviving at least 30 days may be quite helpful to healthcare providers in setting expectations and goals with patients after ACS.

Project description:ObjectivesTo determine the associated factors for discontinuation of statin use 1 year after discharge in patients who survived from acute coronary syndrome (ACS) in China.Settings75 hospitals across China.DesignA cohort follow-up study.ParticipantsThe study included 10 337 patients with ACS hospitalised in 2007-2010 and discharged with statins from 75 hospitals in China in the Clinical Pathways for Acute Coronary Syndromes in China Study-Phase 2 (CPACS-2), who were followed-up at 6 and 12 months postdischarge.Primary outcome measuresThe primary outcome was the discontinuation of statin use defined as not in current use of statin at either 6-month or 12-month follow-up.ResultsMultivariable logistic regression model showed that patients who did not have cholesterol measurement (adjusted OR=1.29; 95% CI: 1.10 to 1.50) and patients with either higher (1.27; 1.13 to 1.43) or lower dose of statin (1.22; 1.07 to 1.40), compared with those with standard dose, were more likely to discontinue the use of statin. In addition, patients on the CPACS-2 intervention pathway (adjusted OR=0.83; 95% CI: 0.74 to 0.94), patients with medical insurance (0.75; 0.67 to 0.85), history of hypertension (0.83; 0.75 to 0.92), high low-density lipoprotein cholesterol (0.70; 0.57 to 0.87) at the baseline, prior statin use (0.73; 0.63 to 0.84), use of atorvastatin (0.78; 0.70 to 0.88) and those who underwent percutaneous coronary intervention or coronary artery bypass grafting during hospitalisation (0.47; 0.43 to 0.53) were less likely to discontinue statin use. The 1-year statin discontinuation rate decreased from 29.5% in 2007-2008 to 17.8% in 2010 (adjusted OR=0.60; 95% CI: 0.51 to 0.70).ConclusionImplementing clinical pathway, enhancing medical insurance coverage, strengthening health education in both physicians and patients, using statin at standard dosage may help improve the adherence to statin use after discharge in Chinese patients with ACS.Trial registration numberAustralian New Zealand Clinical Trials Registry (ACTRN12609000491268).
