Association between Illness Perception and Emotional Status in Iranian Patients after Heart Transplantation

Background: Heart transplantation is a major procedure which imposes high emotional stress on patients. Illness perception (IP) is a psychological issue which affects psychological adjustment after transplantation. This study aimed to investigate the association between IP and emotional status in Iranian post-heart transplantation patients. Methods: The present cross-sectional study, conducted between 2018 and 2019 in Imam Khomeini Hospital, Tehran, Iran, recruited 121 post-heart transplantation patients. IP was measured using the Brief Illness Perception Questionnaire (B-IPQ), and emotional status was measured using the Hospital Anxiety and Depression Scale. The association between IP and depression/anxiety was assessed. Results: Men comprised 80.2% of the study population. The mean age of the participants was 43.9±12.95 years. Definite caseness for depression and anxiety was reported in 11.6% and 18.2% of the participants, respectively. The median score of IP was 55. The association between anxiety and IP in total IP and the 3 dimensions of IP was statically significant (P=0.015, P=0.018, P=0.002, and P=0.023 for the cognition, emotion, and understanding dimensions and the total IPQ, respectively). Additionally, the association between depression and IP was significant (P=0.001, P=0.029, and P=0.002 for the cognition and emotion dimensions and the total IPQ, correspondingly, except for the understanding dimension). Furthermore, lower levels of anxiety in the patients showed a greater impact on IP than did depression. Conclusion: There was a significant association between IP and depression and anxiety in our study population. Therefore, the diagnosis and management of anxiety and depression in heart transplantation patients may improve IP. The cross-sectional design of the present study precluded an investigation of the causality between IP and emotional status.

Tricuspid regurgitation improvement in relation to the amount of pulmonary artery pressure reduction

BACKGROUND

Given the common concomitance of tricuspid regurgitation (TR) with significant mitral stenosis, we aimed at exploring the relation between TR severity and pulmonary artery hypertension (PAH) in patients who underwent mitral balloon valvotomy (MBV).

METHODS

We analyzed the echocardiography data of 133 consecutive patients (82.0% female, mean age 44.68 ± 12.56 years) with different degrees of TR severity that underwent MBV between April 2006 and March 2008. The pulmonary artery systolic pressure (PAPs) > 35 mmHg was considered as PAH.

RESULTS

Before MBV, 36.20% of the patients had moderate to severe TR, 92.5% PAH, and 18.0% right ventricular (RV) dilation (RV dimension ≥ 33 mm). After MBV, TR severity improved in 41.4%, worsened in 8.3%, and did not change in 50.4%. Before and after MBV, PAPs was significantly correlated with TR severity, and the mean PAPs change in patients with improved TR was significantly more than that of patients without TR improvement (p value = 0.042). Tricuspid regurgitation severity and mean PAPs (from 52.83 ± 18.82 to 35.89 ± 9.39 mmHg) decreased significantly after MBV (both p values < 0.001); this reduction was significantly correlated to the amount of PAPs decrease. A cut-off point of ≥ 19 mmHg reduction in PAPs had a specificity of 71.79% and sensitivity of 52.73% to show TR severity improvement (by Receiver-Operative-Characteristics analysis). The mean of RV dimension decreased from 28.94 ± 5.43 to 27.95 ± 4.67 mm (p value < 0.001). In contrast to patients with RV dilation, TR reduced significantly in patients without RV dilation (p value < 0.001).

CONCLUSION

Improvement in TR severity was directly correlated with the amount of PAPs reduction after MBV. More studies are needed to better define a cut-off value for PAPs reduction related to TR severity improvement.
