We studied whether previously developed cardiac risk scores-including history, ECG, age, risk factors, and troponin (HEART); Thrombolysis in Myocardial Infarction (TIMI); Global Registry of Acute Coronary Events (GRACE); and Emergency Department Assessment of Chest Pain (EDACS)-could be applied to predict major adverse cardiac events (MACE) in patients with possible coronary artery disease, including anginal equivalents. Patients with chest pain or anginal equivalents who underwent coronary computed tomographic angiography were included. The primary outcome was 30-day MACE. ⋯ At a sensitivity level of a < 2% rate of misses, the negative predictive value of the HEART score (1.0) outperformed those of the GRACE (0.932) and EDACS (0.964). The HEART score appeared to be more predictive of MACEs than the TIMI, GRACE, and EDACS in patients with chest pain or anginal equivalents. However, previously suggested cutoff could not safely identify low-risk patients for early discharge because of the unacceptably high rate of missed MACEs.

Self-management schemes and mobile apps can be used for the management of hypertension in the community, but the most appropriate patient population is unknown. To explore whether the Chinese Health Literacy Scale (CHLSH) can be used to screen for appropriate patients with hypertension for self-management and to evaluate the clinical effectiveness and health economic evaluation of three hypertension management schemes. This was a prospective study performed from March 2017 to July 2017 in consecutive patients with primary hypertension and of 50-80 years of age from the Jinyang community, Wuhou District, Chengdu. ⋯ The costs required for obtaining 1 QALY when managing for 6 months were: 30,869 yuan for self-management; 48,628 yuan for traditional management; and 43,199 yuan for the mobile app. The CHLSH can be used as a tool for screening patients with hypertension for self-management. The cost-effectiveness of self-management was optimal.

Defective spleen function increases susceptibility to bacterial infections which can be prevented by vaccine prophylaxis. Splenic hypofunction can be found in a number of autoimmune disorders; however, no data are available regarding autoimmune atrophic gastritis (AAG), autoimmune enteropathy (AIE) and autoimmune liver disease (AILD). Peripheral blood samples from patients with AAG (n = 40), AIE (n = 3) and AILD (n = 40) were collected. ⋯ Defective splenic function was observed in 22 of the 40 patients with AAG (55.0%), in two of the three patients with AIE (66.6%) and in 35 of the 40 patients with AILD (87.5%). As expected, in untreated CD, refractory CD and UC there was a high prevalence of hyposplenism (43.7%, 88.2% and 54.4%, respectively). Due to the high prevalence of splenic hypofunction, patients with AAG, AILD and AIE should undergo pitted red cell evaluation and, if hyposplenic, they should be candidate to vaccine prophylaxis against encapsulated bacteria.

We retrospectively studied the association between changes in exercise capacity at discharge from a home-based exercise program and the risk of all-cause mortality among patients with peripheral artery disease (PAD) and claudication. The records of 1076 consecutive PAD patients were assessed between 2003 and 2013. The exercise program was prescribed during a few visits and executed at home at symptom-free walking speed. ⋯ The completers (71 ± 9 years; 88% exercise sessions completed) showed significant improvements in the lowest ABI (from 0.62 ± 0.18 to 0.67 ± 0.19) and Smax (from 3.3 ± 1.1 to 3.8 ± 1.1 km h-1) at discharge. The completers who reached the clinically important difference of Smax ≥ 0.4 km h-1 at follow-up showed a significantly lower mortality risk (25% vs. 30%; HR 0.72; 95% CI 0.55-0.93) as well a lower rate of hospitalizations (p < 0.001). In conclusion, in PAD patients, active participation in a home-based exercise program was associated with a lower rate of death and better long-term clinical outcomes, particularly for those who attained a moderate increase in exercise capacity.

More clinical data are required on the safety of direct oral anticoagulants (DOACs). Although patients treated with warfarin and DOACs have a similar risk of bleeding, short-term mortality after a gastrointestinal bleeding (GIB) episode in DOAC-treated patients has not been clarified. The objective of this study was to assess differences in 30-day mortality in patients treated with DOACs or warfarin admitted to the emergency department (ED) for GIB. ⋯ In the 112 DOAC-treated patients, the mortality rate was 7.1% (8/112). The Cox regression analysis, adjusted for possible clinical confounders, and the Kaplan-Meier curves did not outline differences between the two treatment groups. The present study shows no differences between DOACs and warfarin in short-term mortality after GIB.
