ARYA Atherosclerosis

BACKGROUND: Although coronary artery bypass graft (CABG) surgery has been reported to be one of the most effective internentions in terms of myocardial salvage, reperfusion itself can cause additional damage to the myocardium. Since there is strong evidence that free radicals are the principal offender in ischemia-reperfusion (I/R) injury, it has been suggested that treatment with antioxidant agents can be protective. Investigations have shown that melatonin secretion is partially disturbed in CABG patients...

BACKGROUND: The important role of lipoproteins, particularly low-density lipoprotein (LDL) and high-density lipoprotein (HDL), has been highly regarded among the known causes of cardiovascular disease (CVD). A wide range of risk factors may cause structural and functional changes in lipoprotein particles, resulting in deposition and formation of atherosclerotic plaques. Homocysteine is one of the most important risk factors in heart disease, and its atherosclerotic properties appear to be related to its intermediate metabolite called homocysteine thiolactone (HCTL)...

BACKGROUND: Coronary artery disease (CAD) is a leading cause of cardiovascular death worldwide. Therefore, assessing knowledge in patients with CAD needs a specific tool. This study aims to carry out the Persian validation of the Coronary Artery Disease Education Questionnaire Short Version (CADE-Q SV) for education of patients undergoing cardiac rehabilitation (CR). METHODS: This study was a cross-sectional study. First, the original version of the CADE-Q SV was translated from English into Farsi using the standard approach...

BACKGROUND: Premature ventricular contractions (PVCs) are early depolarizations of the myocardium which originate from the ventricle. PVCs have previously been considered a benign condition. The clinical significance of PVCs in patients without structural heart disease is controversial. METHODS: In this cross-sectional study, patients with a palpitation complaint who underwent electrocardiography (ECG) Holter recording for 48 hours were analyzed. Patients with frequent PVCs (more than ten times in 1 hour) were identified and enrolled in the study...

BACKGROUND: Coronary artery calcification (CAC) is an important marker of total burden of coronary atherosclerosis. Furthermore, it is a measure of subclinical atherosclerotic disease that correlates well with the cardiovascular risk. The aim of our study was to determine the role of the different lipid parameters in prediction of calcification in coronary arteries using multidetector computed tomography (MDCT). METHODS: This study was conducted on 120 patients presenting to the clinic with typical or atypical chest pain or dyspnea on exertion, or equivocal stress test results along with standard cardiac risk factors; they all underwent computed tomography (CT) coronary angiography...

BACKGROUND: Hypertension (HTN) is the second leading risk factor for death and disability. One fourth of healthcare in Eastern Europe and Central Asia is being spent on blood pressure (BP)-related diseases. An important situation in patients with high BP is hypertensive crisis (BP > 180/120 mmHg), which is divided to hypertensive emergency and urgency. Therefore, here, we decided to compare the effect of captopril and clonidine in patients with hypertensive urgencies, and their side effects...

BACKGROUND: Atrial septal defects (ASDs) are one of the most common congenital cardiac abnormalities. Repair of these defects is a quite secure and routine operation. The most common complications were postoperative atrial arrhythmias, sinus arrhythmia, and atrioventricular (AV) blocks requiring pacemaker implantation, mediastinal bleeding, and transient ischemic attacks (TIAs) or strokes. Iatrogenic diversion of the inferior vena cava (IVC) to the left atrium (LA) during surgical closure of an ASD is a very rare complication...

BACKGROUND: Given the role of post-traumatic stress disorder (PTSD) in morbidity and mortality of cardiac patients, the present study was conducted to determine the relationship between the perception of heart disease and severity of PTSD symptoms. METHODS: Sampled using simple random sampling, 202 cardiovascular patients (50.5% women) were selected and included in this cross-sectional study. The patients admitted to a hospital from January to May 2017 in western Iran were selected and asked to complete the self-report demographic and cardiac risk factors inventory, Brief Illness Perception Questionnaire (Brief-IPQ), and National Stressful Events Survey PTSD Short Scale (NSESSS) checklist...

BACKGROUND: Depression is common in patients with cardiovascular disease (CVD). Home-based cardiac rehabilitation (HBCR) is a program that alleviates depression. This study aimed to determine and compare HBCR programs and usual care (UC) effects on depression control in patients with ischemic heart disease (IHD). METHODS: This clinical trial study was performed on 259 patients with IHD that were randomly allocated to the HBCR and UC groups for stress management...

BACKGROUND: Childhood obesity and hypertension (HTN) are among serious global health concerns. Since risk factors of cardiovascular diseases (CVDs) should be managed early in life and there is little information about children under the age of 6 in the community, the study was designed aiming to address these issues. METHODS: This cross-sectional study was performed on 1,091, 3-6-year-old children in Gorgan City, located in north of Iran. Height, weight, body mass index (BMI), and blood pressure were measured using standard techniques...

BACKGROUND: It seems that the time of performing cardiac rehabilitation is important in determining the risk of cardiac complications in patients with myocardial infarction (MI). The present study aimed to investigate the effects of a home-based cardiac rehabilitation program (HCRP) conducted in either the morning or evening on cardiometabolic risk factors in phase IV (maintenance) MI patients. METHODS: In this randomized controlled clinical trial, 80 patients with MI were divided into 2 groups of intervention and control (40 individuals per group)...

BACKGROUND: Cyanoacrylate (CA) has been used as an embolizing agent in the treatment of greater saphenous vein (GSV) insufficiency in recent years and the results regarding the use of this method have started to be published. To the best of our knowledge, the publications in literature do not mention about a significant negative effect of endovenous CA (EVCA) embolization. We aimed to evaluate the effects and undesirable events of this relatively new treatment method and compare them with literature, using the follow-up data of our patients...

BACKGROUND: Fractional excretion of sodium (FENa), the reflection of sodium (Na) handling by the kidney during natriuresis, is influenced by exo- and endogenous factors that have a powerful impact on renal function. We performed this study to define the correlation between FENa and worsening renal function (WRF) and assess the value of FENa in the length of hospital stay and in-hospital mortality in the patients with acute decompensated heart failure (ADHF). METHODS: This prospective observational study was performed in two tertiary governmental heart centers located in Ahvaz, Iran, from March 2019 to March 2020...

BACKGROUND: Interleukin-18 (IL-18) is a pro-inflammatory and pro-atherogenic factor, and its blood level has shown a direct correlation with atherosclerosis. We aimed to evaluate the serum IL-18 level in patients with systemic lupus erythematosus (SLE) and its relationship with the intima-media thickness (IMT) of the carotid artery in these patients, as an indicator of atherosclerosis. METHODS: In this cross-sectional study, 60 patients as the patient group and 30 healthy volunteers as the control group [matched sex, age, and body mass index (BMI)] were selected, and their disease status and general data were gathered using the Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) form...

BACKGROUND: Heart failure is one of the most common syndromes in the world and Iran. Caring for heart failure patients can cause a burden on their caregivers. Traditional and modern treatment techniques are often used for patients with heart failure. This study was conducted with the aim to " determine the impact of telenursing on short-term caregiver burden of patients with heart failure discharged from hospitals in Iran". METHODS: This randomized clinical trial (RCT) was undertaken in Kerman, Iran, in 2018-2019...

BACKGROUND: During ongoing coronavirus disease 2019 (COVID-19) pandemic, social isolation and lockdown measures were implemented to prevent spread of virus which created enormous challenges to patient healthcare. In order to overcome these challenges, teleconsultation (telecardiology) was initiated. Objective of this study was to assess outcome of telecardiology using audio/visual/audio-visual consultation among patients with implantable cardiac devices. METHODS: Telecardiology was performed (either physician-initiated or patient-initiated) among 1200 patients over a five-month period (July 13 to December 13, 2020) to review health status of patients to decide further course of treatment and to access their satisfaction level with telecardiology...

BACKGROUND: Atrioventricular node (AVN) is an interatrial septum structure located at the apex of triangle of Koch that modulates the transmission of impulses from atria to the ventricles. Vagally mediated AVN block with high frequency stimulation (HFS) was investigated in a few animal and human studies, but prolonged ventricular asystole that was induced by a low frequency proximal coronary sinus (CS) overdrive pacing has rarely been reported. CASE REPORT: A 40-year-old man was admitted in our hospital for evaluation of syncope and palpitation...

BACKGROUND: Understanding the close interaction between the specialties of cardiology and oncology is necessary for early detection of cardiovascular disease (CVD) events in cancer patients. For the risk assessment of CVD in Breast and Colorectal Cancers (CIBC) study, in the current study we aimed to validate a questionnaire for the assessment of clinical history in patients with breast cancer and colorectal cancer (CRC). METHODS: We determined the content validity of the questionnaire using the 2 indexes of content validity ratio (CVR) and content validity index (CVI) to examine the specificity, simplicity, clarity, and transparency of the items...
