Relation of Systolic Blood Pressure on the Following Day with Post-Discharge Mortality in Hospitalized Heart Failure Patients with Preserved Ejection Fraction.
The clinical scenario, which is based on systolic blood pressure (SBP) upon admission, is useful for classifying and determining initial treatment for acute heart failure (HF). However, the prognostic significance of SBP following the initial treatment is unclear. The Japanese Heart Failure Syndrome with Preserved Ejection Fraction (JASPER) registry is a nationwide, observational, and prospective registration of consecutive Japanese patients hospitalized with HF with preserved ejection fraction (HFpEF) and left ventricular ejection fraction ≥ 50%. ⋯ Compared to the normal and high groups, the low group demonstrated a higher prevalence of atrial fibrillation (67.1%, 63.9%, and 47.8%, P = 0.026) and the lowest left ventricular outflow tract velocity time integral determined by echocardiography (16.4 cm, 19.4 cm, and 23.3 cm, P = 0.001). In the multivariable Cox proportional hazard analysis, low SBP on the day following hospitalization was an independent predictor of all-cause death (hazard ratio 1.868, 95% confidence interval 1.024-3.407, P = 0.042) and the composite endpoint (hazard ratio 1.660, 95% confidence interval 1.103-2.500, P = 0.015). Classification based on SBP on the day following initial treatment predicts post-discharge prognosis in hospitalized patients with HFpEF.

Impact of Postprocedural TIMI Flow on Long-Term Clinical Outcomes in Patients with Acute Myocardial Infarction.
This study aimed to evaluate the clinical prognostic implications of postprocedural Thrombolysis in Myocardial Infarction (TIMI) flow in acute myocardial infarction patients. A total of 2796 ST-elevation myocardial infarction (STEMI) and 1720 non ST-elevation myocardial infarction (NSTEMI) patients treated in 8 hospitals affiliated with the Catholic University of Korea and Chonnam National University Hospital were analyzed. The study populations were divided according to the final TIMI flow. ⋯ In STEMI patients, good postprocedural TIMI flow after PCI was associated with favorable clinical outcomes. And the effect of poor TIMI flow in STEMI was on death, not the components of MACE. Meanwhile, postprocedural TIMI flow had no effect on long-term outcomes in NSTEMI patients.

Incidence and mortality of acute myocardial infarction. A population-based study including patients with out-of-hospital cardiac arrest.
The in-hospital mortality rate of acute myocardial infarction (AMI) is improving. In Japan, little information exists concerning the incidence and mortality of AMI. Therefore, our population-based analysis examined the incidence and mortality rate in AMI cases in individuals that lived in the Matsumoto region in 2002. ⋯ The population-based mortality rate of AMI was 34% to 42%. The mortality rate of AMI remains high, and most deaths occur outside of the hospital. Prehospital care may lower the mortality rate of AMI.
