Aim: To describe the relative impact on survival of the delay from estimated time of collapse to call for an ambulance among patients who suffer from a bystander witnessed out of hospital cardiac arrest of a cardiac aetiology.
Methods: A majority of all ambulance organizations in Sweden (covering 85% of Sweden inhabitants) participate in a National survey of out of hospital cardiac arrest.
Results: In all there were 9340 patients with a bystander witnessed cardiac arrest of a cardiac aetiology in whom cardiopulmonary resuscitation (CPR) was attempted participating in this survey. Survival at one month among patients with a delay between estimated time of collapse and call for ambulance of < or =4 min (median) was 6.9% versus 2.8% among patients with a median of >4 min (P<0.0001). When adjusting for age, sex, initial rhythm, estimated interval between collapse and start of CPR, place of arrest and the interval between call for ambulance and arrival of the rescue team, the odds ratio for survival was 0.70 (0.95% CI. 0.58-0.84) per unit increase of the natural logarithm of delay in minutes between collapse and call.
Conclusion: Among patients with a bystander witnessed out of hospital cardiac arrest of a cardiac aetiology increased delay from estimated time of collapse to call for an ambulance decreased the chance of survival.

Experience with sodium glucose cotransporter-2 inhibitors in adult patients with Fontan circulation.
Adv Clin Exp Med
January 2025
Institute of Cardiology, Jagiellonian University Medical College, Cracow, Poland.
Background: We still know little about the effective pharmacological treatment of heart failure (HF) associated with the Fontan circulation. One of the new options may be sodium glucose cotransporter-2 inhibitors (SGLT2i), which have been proven effective in classic forms of left ventricular HF.
Objectives: To evaluate the effect and safety of SGLT2i inclusion in adults with Fontan circulation.
Determinants of Racial and Ethnic Differences in Maternal Cardiovascular Health in Early Pregnancy.

Department of Preventive Medicine, Northwestern University Feinberg School of Medicine, Chicago, IL. (N.A.C., X.H., L.C.P., H.N., N.S.S., A.M.P., P.G., D.M.L.-J., K.N.K., S.S.K.).
Background: Suboptimal cardiovascular health (CVH) in pregnancy is associated with adverse maternal and offspring outcomes. To guide public health efforts to reduce disparities in maternal CVH, we determined the contribution of individual- and neighborhood-level factors to racial and ethnic differences in early pregnancy CVH.
Methods: We included nulliparous individuals with singleton pregnancies who self-identified as Hispanic, non-Hispanic Black (NHB), or non-Hispanic White (NHW) and participated in the nuMoM2b cohort study (Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be).
Validation Status of Electronic Sphygmomanometers in China: A National Survey.
Hypertension
January 2025
Clinical Research Institute, Institute of Advanced Clinical Medicine, Peking University, Beijing, China (X.Z., W.X., Y.W.).
Background: Although the information on the validation status of electronic sphygmomanometer (ES) devices in use in health care institutions and households is much more clinically relevant than that of ES models available on the market, it remains insufficient.
Methods: A national survey was conducted across all administrative regions of mainland China to assess the validation status of ESs. Fifty-eight cities were selected with stratification by municipality, provincial capital, and other cities, and health care institutions and households in each city were chosen by convenience to identify ES devices in use according to the study protocol.

Epidemiologic and clinical characteristics and course of acute heart failure and cardiogenic shock diagnosed in emergency departments.

Servicio de Urgencias, Hospital Clínic Barcelona, IDIBAPS, Universitat de Barcelona, España.
Objective: To describe the characteristics of patients diagnosed with acute heart failure (AHF) in emergency departments (EDs) who develop cardiogenic shock (CS) not associated with ST-segment elevation acute coronary syndrome (STACS).
Methods: Information for patients diagnosed with AHF in 23 Spanish EDs and registered between 2009 and 2019 were included for analysis if the patients developed symptoms consistent with CS. We described baseline clinical characteristics related to cardiac decompensation and CS, as well as 30-day mortality.
