RESUMO
BACKGROUND: Chronic heart failure (CHF) is the terminal stage of cardiovascular disease. OBJECTIVE: In this study, the "hospital-to-home + online-to-offline" (H2H + O2O) care scheme was implemented for patients with CHF during vulnerable periods, and its effect was evaluated. METHODS: Patients with CHF in the cardiovascular department of a Class III/Grade A hospital in Jiangxi Province from January to December 2020 were selected using a convenience sampling method and randomly divided into a control and intervention group (n= 100 each). The patients in the control group received routine in-hospital treatment and out-of-hospital follow-up, while in the intervention group, a multi-disciplinary cooperation team with CHF specialist nurses evaluated and stratified the patients before discharge and formulated individualized prescriptions and care plans. Based on the "Health & Happiness" chronic disease follow-up application designed for this study, the specialist nurses provided patients with one-to-one guidance. After three months, the cardiac function, heart failure knowledge, self-care behavior, and re-hospitalization rate of the patients were compared between the two groups. Cardiac function was evaluated by the serum B-type natriuretic peptide (BNP), the left ventricular ejection fraction (LVEF), and a six-minute walking test (6MWT). Heart failure knowledge and self-care behavior was assessed using specific questionaries. RESULTS: The level of cardiac function in the intervention group was significantly higher than that in the control group, and the difference was statistically significant (P< 0.001). The mastery of heart failure knowledge and self-care behavior in the intervention group were significantly higher than those in the control group, and the differences were statistically significant (P< 0.05). The re-hospitalization rate due to CHF in the intervention group was 21.0%, which was lower than that in the control group (35.0%), and the difference was statistically significant (P< 0.05). CONCLUSION: The H2H + O2O care scheme can be used for the transition of vulnerable patients with CHF from the hospital to family care to improve the patients' level of cardiac function, elevate their knowledge level and self-care abilities, and improve their overall health outcomes.

OBJECTIVE: The aim of this study is to evaluate the impact on blood pressure (BP) of a 10°C change in room temperature (between 18°C and 28°C). METHODS: A total of 112 volunteers, 56 males and 56 females, 55 with and 57 without hypertension, were enrolled in the study. First, the participants were placed in a 25°C room. Second, they were randomly assigned to either a 28°C (group A) or an 18°C room (group B). Finally, they were moved from the 28°C to the 18°C room, or vice versa. They stayed in each room for 20 minutes. Seated BP was measured at the 17th and 19th minute in each room, and the average was used. The difference in the subject's BP between the second two rooms was recorded as delta BP. RESULTS: The baseline systolic BP (SBP), age, gender distribution, and incidence of hypertension were similar between the two groups. In group A, the decrease in room temperature of 10°C induced a mean rise in SBP of 4.1 mmHg. In group B, the increase of 10°C caused SBP to decrease by 4.0 mmHg. When compared with the group without hypertension, the group with hypertension had a significantly higher rise in mean SBP (6.8 vs 1.2 mmHg) as a result of the decrease in temperature and a significantly higher drop in SBP (7.3 vs 1.2 mmHg) as a result of the increase in temperature. The participants in the group with hypertension were older. CONCLUSION: A 10°C change in room temperature, from 18°C to 28°C, for 20 min can cause a significant change in SBP. The extent of this change is more obvious in the older group.
