A Combination of Heart Rate-Corrected QT Interval and GRACE Risk Score Better Predict Early Mortality in Patients with Non-ST Segment Elevation Acute Coronary Syndrome.

Objective: This study aimed to evaluate whether the addition of heart rate-corrected QT inter- val prolongation to the Global Registry of Acute Coronary Events risk score improves the pre- dictive value for early mortality in patients with non-ST segment elevation acute coronary syndrome.

Methods: We retrospectively screened our database for consecutive non-ST-segment eleva- tion acute coronary syndrome patients between January 2017 and July 2019. The demographic and clinical parameters were acquired via chart review.

The role of prognostic nutritional index in predicting amputation in patients with lower extremity peripheral artery disease.

Lower-extremity peripheral artery disease (PAD) can lead to a wide spectrum of symptoms that can progress from claudication to amputation. The prognostic nutritional index (PNI), which is calculated using the levels of albumin and lymphocyte, is an accepted indicator of immunological and nutritional status. In this study, the association between nutritional status determined using the PNI, and extremity amputation in patients with lower-extremity PAD was investigated.
