RESUMO
Objectives:This study aimed to evaluate the predictive value of the CHA 2DS 2-VASc score for in-hospital outcomes of patients with acute myocardial infarction (AMI). Methods:Data of 23 728 patients from the China patient-centered Evaluative Assessment of cardiac Events (China PEACE)Retrospective Acute Myocardial Infarction Study were analyzed retrospectively. The patients were categorized into 3 groups according to the CHA 2DS 2-VASc scores: the low score group (score 1-3), the middle score group (score 4-6) and the high score group (score 7-9). The in-hospital outcomes included major adverse cardiovascular events (MACE), death, death or withdrawal from treatment, reinfarction, ischemic stroke,etc. The CHA 2DS 2-VASc score was incorporated into multivariate Cox regression analyses to determine its independent impact on in-hospital outcomes. Receiver operating Characteristic (ROC) curves were constructed, and the area under the curve (AUC) was used to evaluate the predictive value of the CHA 2DS 2-VASc score for in-hospital mortality and death or withdrawal from treatment, respectively. Results:The patients had a median age of 66 (56,75) years, and 30.7% of them were females. Patients with higher CHA 2DS 2-VASc scores had a higher in-hospital mortality and more in-hospital complications (all P<0.001). After adjustment of baseline covariates, the subjects in the high score group were associated with high risks of in-hospital mortality ( OR=6.13, 95% CI 4.77-7.87, P<0.001), death or treatment withdrawal ( OR=6.43, 95% CI 5.16-8.00, P<0.001) and MACE ( OR=4.94, 95% CI 4.06-6.01, P<0.001). The AUCs of the CHA 2DS 2-VASc score were comparable with those of the mini-global registry of acute coronary events(mini-GRACE)score in evaluation of in-hospital mortality (0.699 vs. 0.696, P=0.752) and the death or treatment withdrawal risk (0.708 vs. 0.713, P=0.489). Conclusions:The CHA 2DS 2-VASc score is an independent predictor of in-hospital outcomes for patients with AMI. Its predictive value was comparable with the mini-GRACE score, which could be used as a simple tool for early and rapid outcome evaluation for AMI patients.
RESUMO
Objective@#To explore the occurrence of cognitive impairment in Chinese heart failure (HF) patients and it's impact on prognosis.@*Methods@#In this prospective observational study, a total of 990 HF patients were enrolled from 24 hospitals in China during December 2012 to November 2014. All patients were administrated with the interview-format Montreal Cognitive Assessment (MoCA), according to which they were divided into MoCA<26 (with cognitive impairment) group and MoCA≥26 (without cognitive impairment) group. Baseline data were collected and a 1-year follow up was carried out. Univariate and multivariate logistic or Cox regression were performed for 1-year outcomes.@*Results@#Cognitive impairment was evidenced in 628 patients (63.4%) and they were more likely to be older, female, and with higher proportion of New York Heart Association(NYHA) class Ⅲ-Ⅳ, chronic obstructive pulmonary disease (COPD), ischemic heart disease, while body mass index (BMI), education level, and medical insurance rate were lower (all P<0.05) as compared to patients in MoCA≥26 group. The rate of percutaneous intervention, device implantation, cardiac surgery and evidence-based medications were significantly lower in MoCA<26 group than in MoCA≥26 group (all P<0.05). During the 1-year follow up, patients in the MoCA<26 group had higher all-cause mortality (10.2%(64/628) vs. 2.2%(8/362), P<0.01), cardiovascular mortality (5.9%(37/628) vs. 0.8%(3/362), P<0.01) and major adverse cardiac and cerebrovascular events (MACCE) (9.6%(60/628) vs. 2.5%(8/362), P<0.01) than patients in the MoCA≥26 group. In univariate regression, MoCA<26 was associated with increased all-cause mortality (HR(95%CI):4.739(2.272-9.885), P<0.01), cardiovascular mortality (HR(95%CI):7.258(2.237-23.548), P=0.001) and MACCE (OR(95%CI):4.143(2.031-8.453), P<0.01). After adjustment by multivariate regression, MoCA<26 was indicated as an independent risk factor for all-cause mortality (HR(95%CI): 6.387(2.533-16.104), P<0.01), cardiovascular mortality (HR(95%CI): 10.848(2.586-45.506), P=0.001) and MACCE (OR(95%CI): 4.081(1.299-12.816), P=0.016), while not for re-hospitalization for HF (OR(95%CI):1.010(0.700-1.457), P=0.957).@*Conclusions@#Cognitive impairment is common in HF patients,and it is an independent prognostic factor for 1-year outcomes. Routine cognitive function assessment and active intervention are thus recommended for HF patients.

Objective To assess and compare the incidence,clinical characteristics,treatment,and prognosis of acute heart failure patients from different grades hospitals in Beijing.Methods In this prospective internet prognosis registered study (Beijing AHF Registry),a total of 3 335 consecutive patients admitted to 14 emergency departments in Beijing from January 1st 2011 to September 23rd 2012 were enrolled.According to hospital grade,these patients were divided into two groups,349 patients were from secondary hospitals,and 2 956 patients were from tertiary hospitals.Results Among the 3 335 patients,the medium age was 71 (58,79) years,and male accounted for 53.16％.The most common underlying disease were coronary disease (43.27％),hypertension (17.73％),cardiomyopathy (16.07％) etc.The average treatment time in Emergency Department was 66.82 h.The emergency department mortality rate was 3.81％ (127 cases).The 30-day and 1-year cumulative all-cause mortality were 15.3％ and 32.27％,respectively.The 30-day and 1-year cumulative all-cause readmission were 15.64％ and 46.89％,respectively.Compared with patients in tertiary hospitals,patients in secondary hospitals had more onset acute heart failure patients (63.64％ vs.49.93％),shorter emergency department treatment time (12 h vs.41 h),lower discharge rate (3.43％ vs.37.45％) and emergency department mortality(1.58％ vs.4.09％).Compared with those in tertiary hospitals,1-year cumulative all-cause mortality (25.6％ vs.33.2％),cardiovascular disease mortality (20.2％ vs.26.0％),aggravated heart failure mortality (22.4％ vs.28.8％) were lower in secondary hospitals.Following propensity score matching,compared to tertiary hospitals,patients in secondary hospitals showed lower utilization rate of beta-blockers and ACEFARB (4.51％ vs.28.17％,1.41％ vs.9.58％),except the pironolactone.Conclusion Acute heart failure in emergency department is associated with a high mortality rate and readmission rate.There is still a big gap between guidelines recommend medication current treatments for acute heart failure.
RESUMO
<p><b>OBJECTIVE</b>This retrospective study is performed to analyze the epidemiological and clinical features of patients with infective endocarditis (IE) hospitalized in Fuwai Cardiovascular Hospital during the latest 7 years.</p><p><b>METHODS</b>This retrospective study included a cohort of 368 infective endocarditis patients hospitalized in Fuwai Hospital form August 2005 to August 2012. Predisposing cardiac diseases, causative organisms, clinical features and outcomes were analyzed. Risk factors related to outcome including NYHA classes, causative organisms and complications, were evaluated.</p><p><b>RESULTS</b>Among the IE patients, 6.8% (25/368) patients had rheumatic heart diseases 31.8% (117/368) had congenital heart diseases, 22.8% (84/368) were post-PCI or operative endocarditis and IE developed in 14.1% (52/368) patients without previous cardiac diseases. Blood culture positive rate was 46.2% (170/368). Streptococci viridians [27.6% (47/170) ]were the most common causative organisms, followed by coagulase-negative staphylococci [15.9% (27/170) ]. Fever and cardiac murmur were the most common clinical presentations. Congestive heart failure was the most common complication [87.8% (323/368)]. Systemic and pulmonary embolism occurred in 16.0% patients, 80.9% IE was detected by echocardiography. In-hospital mortality rate was 6.7%, mostly due to refractory congestive heart failure and sepsis. Subgroup analysis showed that incidence of post-PCI or operative endocarditis was significantly higher in IE patients hospitalized after 2009 compared to IE patients hospitalized before 2009 (27.5% vs. 19.2%, P < 0.05) . Higher incidence of staphylococcal infection was evidenced in mechanical valves than in native valves (44.4% vs. 19.8%, P < 0.05).</p><p><b>CONCLUSION</b>During the past decade, there is a significant change on epidemiology and clinical features of IE in China. Incidence of post-surgical and interventional IE increased significantly. Staphylococcal and Gram negative bacilli infection are major pathorganisms of endocarditis of mechanical valves. Due to the lower positive rate of blood culture, echocardiography serves as the most important diagnostic tool for infective endocarditis.</p>
