Article Synopsis
- The LIVE-LQTS study aimed to investigate whether vigorous exercise increases the risk of ventricular arrhythmias in individuals with congenital long QT syndrome (LQTS) by tracking participants' activity and health events over three years.
- Among 1,413 participants, 52% engaged in vigorous exercise, and the study found similar rates of serious cardiac events (2.6% in vigorous exercisers vs. 2.7% in non-vigorous) suggesting that vigorous exercise may not significantly increase risk for these individuals.
- The results had a hazard ratio of 0.97, indicating that vigorous exercisers experienced similar or potentially lower rates of adverse events than those who did not exercise vigorously, providing insight into safe exercise practices for LQ
Article Synopsis
- The study investigates whether vigorous exercise increases the risk of ventricular arrhythmias and mortality in individuals with hypertrophic cardiomyopathy (HCM).
- Researchers enrolled 1,660 participants aged 8 to 60 with HCM or its genetic markers, categorizing them by their exercise levels (sedentary, moderate, vigorous).
- The primary outcomes included serious events like death and arrhythmias, with findings analyzed by an unbiased committee to evaluate the effects of exercise intensity on these health risks.
Background Recently there has been increased interest in a possible association between mast cell activation (MCA) disorder and postural orthostatic tachycardia syndrome (POTS). This study examined the frequency with which symptoms and laboratory findings suggesting MCA disorder occurred in patients diagnosed with POTS. Methods and Results Data were obtained from patients in whom symptoms and orthostatic testing were consistent with a POTS diagnosis.
