Deciphering the Psychological Characteristics of Takotsubo Cardiomyopathy and Acute Myocardial Infarction.

Abstract

Background/Objectives: Takotsubo syndrome (TTS) shares many clinical features with acute myocardial infarction (AMI); however, its underlying pathophysiology remains elusive due to specific characteristics (i.e., reversibility, presence of stressors, and low mortality rate). Emerging evidence suggests that TTS often emerges following significant somatic, emotional, or psychological stressors. Several studies have investigated the biological factors that may contribute to the onset of TTS, including the release of stress hormones. However, the psychological characteristics associated with TTS, which may be useful for differentiating TTS from other cardiovascular conditions, remain poorly explored. This study aims to overcome these limitations by evaluating whether certain psychological features may allow this specific clinical condition to be differentiated from other cardiovascular conditions. Methods: This study compared three groups of individuals: patients with TTS (N = 56), patients with AMI (N = 52), and individuals without a history of cardiovascular disease (N = 56). Patients were examined three months after the acute phases. The objective was to identify and examine multiple psychological factors involved in TTS, including state and trait anxiety, symptoms of depression, psychological symptoms, distress, perceived social support, and health locus of control. Results: The results indicate that patients with TTS exhibited higher levels of somatization, trait anxiety, obsessive-compulsiveness, and overall psychological distress than patients with AMI and control groups. These findings were associated with an internal health locus of control and low-risk lifestyles. Conclusions: This psychological exploration of TTS reveals a multifaceted relationship between the mind and the heart, challenging traditional notions of cardiovascular pathophysiology and suggesting the importance of considering the cardio-psychological health of patients in both preventive and intervention programs.
