Key result
Coronary artery ectasia was associated with a significantly higher incidence of abnormal heart rate recovery compared to healthy controls (44% vs. 14%, P=0.002).
Why the study?
Are heart rate variability and heart rate recovery altered in patients with coronary artery ectasia compared to healthy controls?
Population
85 individuals, comprising 50 consecutive patients with coronary artery ectasia and 35 asymptomatic healthy…

Hypothesis-generating for autonomic dysfunction in coronary artery ectasia; larger prospective studies needed to assess prognostic relevance.
Case-Control (n=85)
Are heart rate variability and heart rate recovery altered in patients with coronary artery ectasia compared to healthy controls?
Absolute Event Rate: 44% vs 14%
p-value: p=0.002
Patients with coronary artery ectasia exhibit reduced heart rate variability and impaired heart rate recovery, suggesting altered autonomic function.
Türker et al. (2009) conducted a case-control in Coronary artery ectasia (n=85). Coronary artery ectasia vs. Asymptomatic healthy individuals was evaluated on Incidence of abnormal heart rate recovery (p=0.002). Coronary artery ectasia was associated with a significantly higher incidence of abnormal heart rate recovery compared to healthy controls (44% vs. 14%, P=0.002).
