Factors That Predict Early Return to Work After Myocardial Infarction: Importance of Coworker Support.

Aim    Myocardial infarction (MI) affects the working-age group and cause many absences and lost days of work. Some occupational factors effect in the prognosis of MI patients. The objective of this study was to determine predictors of early, late and no return to work (RTW) after MI.Material and methods    In this cohort study, 240 pre-employed, male patients with MI from April 2020 through February 2022 provided data about their demographic, occupational, psychosocial, and medical information. Data was also collected about the treatment they received as patients, their feelings about socioeconomic support, and RTW time. RTW within two weeks after MI was defined as early RTW. The relationships of these variables and with early RTW and with late or no RTW were analyzed.Results    Ninety-four patients (39.6 %) returned to work within two weeks after MI, whereas 207 patients (87.3 %) returned to work by the end of six months. Many variables, including coworker support, were associated with early RTW in a univariate analysis. Regression analysis revealed that age, coworker support, marital status, the patient's own estimated RTW time, the number of the vessels with occlusion, and comorbidity were predictors of early RTW. Of these factors, only coworker support would be subject to modification.Conclusions    This study indicates that improving support from coworkers can increase early RTW after MI.

Retrosternal hematoma causing torsade de pointes after coronary artery bypass graft surgery; a case report.

Myocardial infarction is among the top causes of mortality worldwide. Survivors may also experience several complications. Infarct-related torsade de pointes (TdP) is an uncommon complication. In the context of myocardial infarction, coronary artery bypass graft (CABG) surgery is the prevalent therapeutic modality associated with several early and late complications. Ventricular tachyarrhythmias, including TdP, because of electrical inhomogeneity, would potentially be a lethal complication of CABG. Here, we report the occurrence of medically intractable TdP in the presence of an uncommon case of a post-CABG retrosternal hematoma. Arrhythmia was properly resolved after hematoma removal surgically. It showed the possibility of a "cause and effect" relationship between these two complications. This unique case emphasizes the post-CABG medically-resistant TdP, considering the mechanical pressure effect of retrosternal hematoma that stimulates this potentially malignant arrhythmia, especially in the absence of electrolyte disturbances and evident symptoms of ongoing ischemia.

Age-dependent association between aneurysmal and isolated redundant inter-atrial septum with patent foramen ovale.

BACKGROUND: Interatrial septum (IAS) could be redundant by abnormal movement with or without aneurysmal bulging. We aimed to determine the prevalence of isolated redundant and aneurysmal IAS motion and their probable relationship with age and presence of patent foramen ovale (PFO) in a large-scale referral center. METHOD: A total of 15,288 patients who underwent transthoracic echocardiography (TTE) at Tehran Heart Center were included From March 2019 to March 2021. Contrast echocardiography was conducted on patients with suspected PFO. Data were retrospectively analyzed from our previously established database. The prevalence of aneurysmal and redundant IAS and their relationship with age and PFO presence was evaluated. RESULTS: Aneurysmal and isolated redundant IAS were present in 4% and 12.4% of the participants, respectively. The aneurysmal group was older, more frequently female and had higher frequency of PFO. The frequency of PFO among patients with aneurysmal IAS was about 14.4% and 5.3% in isolated redundant IAS patients. In both groups, the prevalence of abnormal IAS motion increased across age groups from the youngest to the oldest, while the prevalence of PFO decreased. CONCLUSION: In conclusion, the frequency of PFO among patients with aneurysmal IAS was about 2.5 times more than that among patients with isolated redundant IAS and 24 times more than the normal population. The increasing trend observed across the aging group proposes a potential role for age in the pathophysiology of abnormal IAS. Furthermore, the decreasing prevalence of PFO among patients underlies its clinical significance as an important risk factor.
