    Abstract Background: Non-ST-segment elevation myocardial infarction (NSTEMI) is more common than ST-segment elevation myocardial infarction (STEMI), consisting of 60-70% of myocardial infarctions. When left ventricular (LV) pressure increases during early systole, regionally ischaemic myocardium with a reduced active force exhibit stretching. The aim of this study was to evaluate the role of this parameter in determining high risk angiographic territory involvement in NSTEMI patients.
    Results: This study was a descriptive correlational research that was conducted on 96 patients with NSTEMI and a left ventricular ejection fraction ≥ 50% who underwent coronary angiography (CAG). Patients were divided into two groups based on having or not having high risk angiographic territory involvement in CAG. All patients underwent a transthoracic echocardiography during the first day of hospitalization and early systolic lengthening (ESL), duration of ESL (DESL), left ventricular global longitudinal strain (LVGLS), pulsed-wave Doppler-derived transmitral early (E wave) and late (A wave) diastolic velocities, and tissue-Doppler-derived mitral annular early diastolic (e') and peak systolic (s') velocities were determined. The results of this study showed DESL, DESL

    Abstract Background: Diabetes mellitus (DM) has been documented among the strongest risk factors for developing heart failure with preserved ejection fraction (HFpEF). The earliest imaging changes in patients with DM are the left atrial (LA) functional and volumetric changes. The aim of this study was to determine the correlation between epicardial fat thickness (EFT) and longitudinal LA reservoir strain (LARS) in patients with type 2 DM (T2DM), as compared with non-diabetic controls.
    Results: The study samples in this case-control study comprised of consecutive patients with T2DM (n=64) and matched non-diabetic controls (n=30). An echocardiography was performed on all patients and EFT, volumetric and longitudinal LARS, left ventricular (LV) global longitudinal strain (LVGLS), pulsed-wave Doppler-derived transmitral early (E wave) and late (A wave) diastolic velocities, and tissue-Doppler-derived mitral annular early diastolic (e') and peak systolic (s') velocities were obtained. The study results demonstrated that the patients with T2DM had thicker EFT (5.96±2.13 vs. 4.10±3.11 mm) and increased LA volume index (LAVI) (43.05± 44.40 vs. 29.10±11.34 ml/m
    Conclusions: LARS is considered as an important early marker of subclinical cardiac dysfunction. Thickened epicardial fat may be an independent risk factor for decreased LA reservoir strain. Diabetics are especially considered as a high risk group due to having an increased epicardial adipose tissue thickness.

    Abstract Persistent truncus arteriosus is a rare congenital cardiac malformation. It is characterized by a single great artery arising from the heart which supplies the aorta, the origin of coronary arteries and pulmonary arteries. Without surgery, prognosis is poor and 90% of these patients die before one year of age. We report a rare case of an asymptomatic 35-year-old woman with uncorrected persistent truncus arteriosus and hypoplastic right and left pulmonary arteries. Hypoplastic branch pulmonary arteries prevented the development of severe pulmonary arterial hypertension.

    Abstract Corona disease 2019 (COVID-19) pandemic continues to spread around the world with no efficacious treatment. Intravenous remdesivir is the only authorized drug for treatment of COVID-19 disease under an Emergency Use Authorization. Remdesivir is a 1'-cyano-substituted adenosine nucleotide prodrug which inhibits viral RNA synthesis. This metabolite is an adenosine analog but with a significantly longer half-life than adenosine. Adenosine is a powerful vasodilator that can cause profound hypotension which is followed by the compensatory release of catecholamines. It can also shorten atrial action potential and refractoriness and lead to atrial fibrillation (AF). These effects may also occur in ventricular cells and predispose patients to ventricular fibrillation. Remdesivir can also induce significant cytotoxic effects in cardiomyocytes that is considerably worse than chloroquine cardiotoxic effects. Remdesivir-induced cardiotoxicity is due to its binding to human mitochondrial RNA polymerase. On the other hand, remdesivir can increase field potential duration with decreased Na

    Abstract Background: The present study aimed to respond to clinical question, can prolonged P-R interval predict clinical outcomes in non-ST elevation acute coronary syndrome patients?
    Methods: This descriptive-analytical study was conducted on cardiac patients. All of the non-ST elevation acute coronary syndrome (NSTEACS) including non-ST elevation myocardial infarction (NSTEMI) and unstable angina patients included in the study. Then they divided into two groups: prolonged P-R interval and normal P-R interval. The patients who had a history of digoxin and calcium channel blocker use, using antiarrhythmic drugs, known valvular or congenital heart disease and connective tissue, unreadable P-R interval and cardiac block were excluded. Data were collected using the questionnaire consisted demographic data and clinical outcomes and a follow-up part was completed by one of the researchers.
    Results: Finally, 248 patients completed the study. The results showed both of the two groups had significant differences in terms of the history of myocardial infarction (MI) (p = 0.018), the level of high-density lipoprotein (HDL) (p = 0.004), heart rate (p = 0.042), inverted T wave (p = 0.017), anterior ST- segment depression (p = 0.008), normal report of coronary angiography (CAG) (p = 0.003), three vessels disease (p = 0.043), left main lesion (p = 0.045) and SYNTAX score (p = 0.032) based on the CAG report. The results of six-month follow-up showed although, the frequency of ischemic stroke, coronary artery disease (CAD) and cardiovascular death were higher in prolonged P-R interval groups. The chi-square test showed this difference was statistically non-significant (p > 0.05). The multivariate logistic regression model revealed non-significant relationships between prolonged P-R interval and SYNTAX score, significant CAD, three-vessel disease, inverted T wave, anterior ST depression, heart rate and HDL.
    Conclusions: Based on the results of our study the six-month follow-up showed non-significant outcomes. Further studies are recommended to assess the long-term outcomes.

    Abstract Background: The prognosis of patients hospitalized with non-ST elevation-acute coronary syndrome (NSTE-ACS) is typically determined by the existence and severity of myocardial necrosis and left ventricular (LV) remodeling.
    Aim: The present study was to assess the association between the E/(e's') ratio and the coronary atherosclerosis severity, measured by the SYNTAX score, in patients with NSTE-ACS.
    Methods: Utilizing a descriptive correlational research design, this study was prospectively conducted on 252 patients with NSTE-ACS, undergoing an echocardiography to determine the left ventricular ejection fraction (LVEF), the left atrial (LA) volume, the pulsed-wave (PW) Doppler-derived transmitral early (E) and late (A) diastolic velocities, and the tissue Doppler (TD)-derived mitral annular early diastolic (e') and peak systolic (s') velocities. After that, a coronary angiography (CAG) was performed, and the SYNTAX score was calculated.
    Results: The patients were divided into two groups, viz., those with the E/(e's') ratio < 1.63 and the cases with the ratio ≥ 1.63. The results revealed that the patients with a high ratio were older, had a higher prevalence of females, a SYNTAX score ≥ 22, and a lower glomerular filtration rate than those with a low ratio (p-value < 0.001). Besides, these patients had larger indexed LA volume and lower LVEF than others (p-value: 0.028 and 0.023, respectively). Furthermore, the multiple linear regression outcomes established a positive independent association between the E/(e's') ratio ≥ 1.63 (B = 5.609, 95% CI 2.324-8.894, p-value = 0.001) and the SYNTAX score.
    Conclusion: The study results demonstrated that the patients hospitalized with NSTE-ACS and the E/(e's') ratio ≥ 1.63 had worse demographic, echocardiographic, and laboratory profiles and a higher prevalence of a SYNTAX score ≥ 22 than those with a lower ratio.

    Abstract Background: Cardiovascular disease is the main cause of death among breast cancer survivors. Several chemotherapy drugs may cause cardiovascular toxicity. Our study aimed to assess the late effects of chemotherapy on left ventricular (LV) systolic and diastolic function in a group of female breast cancer survivors.
    Methods: Our study was a case-control study consisted of 60 breast cancer survivors who had undergone chemotherapy for more than 5 years and a control group of 49 women without breast cancer. All patients underwent echocardiography and left ventricular ejection fraction (LVEF), global longitudinal strain (GLS), pulse-Doppler early transmitral peak flow velocity (E wave), early diastolic (e'), and left atrial (LA) diameter were calculated.
    Results: The mean LVEF and GLS were reduced in chemotherapy group (51.63±7.93% vs. 55.37±3.50%, P=0.002 and -17.99±3.27% vs. -19.25±2.27%, P=0.025). Also, the chemotherapy group had a larger left ventricular end-systolic internal diameter than the control group (1.74±0.44cm/m
    Conclusion: Breast cancer survivors might have an excess risk of having subclinical LV dysfunction over time. These findings present the potential benefits of echocardiographic assessment in breast cancer survivors.

    Abstract Glycated hemoglobin (HbA1c) is a useful biomarker for the diagnosis of diabetes and also for determination of individuals with an increased risk of a severe disease. Some subtle changes in myocardial contractile function is measurable by post-systolic index (PSI) which is defined as late systolic shortening after aortic valve closure. The aim of our study was to determine the relationship between HbA1c and PSI in patients with non-apparent coronary artery disease (CAD) on angiograms. This study was a historical cohort study on 85 consecutive patients with a left ventricular ejection fraction ≥ 50% and non-apparent CAD on angiogram. Patients were divided into two groups based on their HbA1c levels, regardless of the diagnosis of diabetes in these patients, to patients with an HbA1c level of equal or higher than 5.7% and those with an HbA1c of less than 5.7%. A speckle-tracking echocardiography was performed for all patients and global longitudinal strain, PSI, left ventricular diameters, left atrial volume, pulsed-Doppler-derived transmitral early (E wave) and late (A wave) diastolic velocities, and tissue-Doppler-derived mitral annular early diastolic (e') and peak systolic (s') velocities were determined. PSI, E/e' ratio, and A wave were higher and e' velocity was lower in patients with HbA1c ≥ 5.7% than those with a level of < 5.7% (P value = 0.04, 0.001, 0.014, and 0.004, respectively). Other echocardiographic variables were not different between two groups. Multiple linear regression analysis showed the association between HbA1c and PSI was independent of other demographic, biochemical, and echocardiographic variables (B = 35.674, 95% CI 10.741-60.606, P value = 0.006). Our study showed PSI is more pronounced in individuals with an HbA1c > 5.7% than those with a lower value in the absence of CAD. Because PSI is an important indicator of adverse outcome and increased mortality, these data can underline the importance of an abnormal HbA1c level and its association with subtle cardiac dysfunction, irrespective of the diagnosis of diabetes in patients with non-apparent CAD.
