The aim of this study was to examine the Intermountain Risk Score (IMRS) for short- and long-term mortality in ST elevation myocardial infarction (STEMI) patients and compare it with the well-known risk scores, such as the Thrombolysis in Myocardial Infarction (TIMI) and the Global Registry of Acute Coronary Events (GRACE). In this retrospective and cross-sectional study, 1057 consecutive patients with STEMI were evaluated. The end-points of the study were short- and long-term mortality. The overall mortality rate was 16% (n = 170 patients). The IMRS was significantly higher in STEMI patients who did not survive compared with those who survived. According to multivariable COX proportional regression analysis, the IMRS was independently related to both short- (HR: 1.482, 95% CI: 1.325–1.675, p < .001) and long-term mortality (HR: 1.915, 95% CI: 1.711–2.180, p < .001). The comparison of receiver operating characteristic curves revealed that the IMRS had non–inferior predictive capability for short- and long-term mortality than the TIMI and GRACE risk scores. To the best of our knowledge, this is the first study to show that the IMRS can predict short- and long-term prognosis of patients with STEMI. Further, the IMRS’ predictive value for overall mortality was non-inferior compared with TIMI and GRACE scores.
Objectives Our primary goal was to utilize pulmonary arterial stiffness (PAS) to demonstrate the early alterations in the pulmonary vascular area in individuals with prior Coronavirus disease 2019 (COVID-19) illness who had not undergone hospitalization. Methods In total, 201 patients with prior COVID-19 infection without hospitalization and 195 healthy, age- and sex-matched individuals without a history of COVID-19 disease were included in this prospective analysis. The PAS value for each patient was calculated by dividing the mean peak pulmonary flow velocity by the pulmonary flow acceleration time. Results The measured PAS was 10.2 (4.11) (Hz/msn) in post-COVID-19 participants and 8.56 (1.47) (Hz/msn) in healthy subjects (p<0.001). Moreover, pulmonary artery acceleration time was significantly lower in patients with a prior history of COVID-19. Multivariable logistic regression analysis revealed that PAS was significantly connected to a prior COVID-19 illness (OR: 1.267; 95%CI:1.142–1.434; p<0.001). The optimal cutoff point for detecting a prior COVID-19 disease for PAS was 10.1 (sensitivity = %70.2, specificity = %87.7). Conclusion This might be the first investigation to reveal that patients with a history of COVID-19 had higher PAS values compared to those without COVID-19. The results of the investigation may indicate the need of regular follow up of COVID-19 patients for the development of PAH, especially during the post-COVID-19 interval.
We report a case of cyst was initially labeled as left ventricular noncompaction cardiomyopathy. An accurate diagnosis is essential to establish the most effective treatment strategy. In particular, echocardiographic examination assists in identifying the correct diagnosis. In this case, two-dimensional and three-dimensional echocardiography and computed tomography were used for definitive diagnosis of cardiac hydatid cyst.
OBJECTIVE:The main objectives of this investigation were to determine whether there were any relationships between corrected cardiacelectrophysiological balance value and National Institutes of Health Stroke Scale scores at admission and discharge in patients with acute ischemic stroke and to assess whether cardiac-electrophysiological balance value was an independent predictor of high National Institutes of Health Stroke Scale scores (National Institutes of Health Stroke Scale score ≥5). METHODS: In this retrospective and observational study, 231 consecutive adult patients with acute ischemic stroke were evaluated. The cardiacelectrophysiological balance value was obtained by dividing the corrected QT interval by the QRS duration measured from surface electrocardiography. An experienced neurologist used the National Institutes of Health Stroke Scale score to determine the severity of the stroke at the time of admission and before discharge from the neurology care unit. The participants in the study were categorized into two groups: those with minor acute ischemic stroke (National Institutes of Health Stroke Scale score=1-4) and those with moderate-to-severe acute ischemic stroke (National Institutes of Health Stroke Scale scores ≥5). RESULTS: Acute ischemic stroke patients with National Institutes of Health Stroke Scale score ≥5 had higher heart rate, QT, corrected QT interval, T-peak to T-end corrected QT interval, cardiac-electrophysiological balance, and cardiac-electrophysiological balance values compared with those with an National Institutes of Health Stroke Scale score of 1-4. The cardiac-electrophysiological balance value was shown to be independently related to National Institutes of Health Stroke Scale scores ≥5 (OR 1.102, 95%CI 1.036-1.172, p<0.001). There was a moderate correlation between cardiacelectrophysiological balance and National Institutes of Health Stroke Scale scores at admission (r=0.333, p<0.001) and discharge (r=0.329, p<0.001). CONCLUSIONS:The findings of this study demonstrated that the cardiac-electrophysiological balance value was related to National Institutes of Health Stroke Scale scores at admission and discharge. Furthermore, an elevated cardiac-electrophysiological balance value was found to be an independent predictor of National Institutes of Health Stroke Scale score ≥5.
