The Post-Traumatic Stress Disorder (PTSD) is an anxiety disorder that can occur after a traumatic event, and that usually causes a significant decrease in the qualityoflife. Individuals diagnosed with PTSD show higher levels of heart rate (HR) when exposed to stressful events, such as sounds and images reminiscent of the traumatic experience. However, studies evaluating the role of peritraumatic HR as a predictor of the development of PTSD have not produced consistent results. The objectives of this study were to investigate whether peritraumatic resting HR a traumatic experience is a risk factor for the development of PTSD and to the severity of PTSD symptoms in adults. A systematic review followed by meta-analysis was carried out looking for studies in the following electronic databases: PUBMED, LILACS; PILOTS, PsycoINFO and Web of Science. We included 17 studies in this systematic review. The results of ten studies were used to calculate the weighted mean differences of HR. Findings from eight studies results were used to calculate the pooled correlation between HR and severity of PTSD symptoms. Meta-regression models were fitted in an attempt to identify variables that could explain the heterogeneity between studies. Peritraumatic HR in patients with PTSD was, on average, 3.98 bpm (p=0.04) higher compared to those without the disorder and the pooled Pearson correlation coefficient was 0.14 (p = 0.05). Consistent with the hypothesis, the peritraumatic resting heart rate after exposure to trauma was higher in patients who developed PTSD. However, closer measurement of the traumatic event and the exclusion of dissociative cases may increase the magnitude of the found effect, making this simple and easily obtained marker a clinically useful predictor of PTSD development.
