Efficacy of trigger point injection therapy in noncardiac chest pain: A randomized controlled trial.

Objectives: This study aimed to compare the effects of trigger point injections and stretching exercises in patients with noncardiac chest pain (NCCP) associated with myofascial pain syndrome.

Patients And Methods: This prospective randomized controlled trial included 50 patients with noncardiac chest pain and trigger points in the pectoralis muscles between October 2019 and June 2020. The patients were randomly assigned to receive trigger point injections into the pectoralis muscles and exercise (n=25; 15 males, 10 females; mean age: 42.

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.

Prevalence and characteristics of coronary artery fistula in adults: coronary angiographic analysis of 18,106 patients.

Aim    Coronary artery fistula (CAF) is a rarely encountered anomaly that is characterized by an abnormal connection between a coronary artery and a cardiac chamber or a great thoracic vessel. Its incidence has not been precisely established due to the large number of undiagnosed cases and it shows heterogeneity in its anatomic configuration and clinical consequences. We aimed to assess the frequency, imaging findings, and clinical features of CAF among patients in our tertiary medical center.
