International Journal of Cardiovascular Practice Vol 3, No 2 (2018)
Publisher : International Journal of Cardiovascular Practice

Introduction: Coronary artery disease is one of the most common causes of mortality around the world. The association between vitamin D deficiency and the incidenceÂ of diseases, such as hypertension, diabetes, and metabolic syndrome, has been demonstrated previously. There have been studies concerning the relationship between vitamin D deficiency and cardiovascular diseases, which have shown different results. Therefore, this study aimed at determining the association between serum levels of vitamin D and acute coronary syndrome.Methods: In this case-control study, serum levels of vitamin D were compared between 50 patients with acute coronary syndrome and 50 individuals without this syndrome. A checklist, including demographic data of patients, comorbidities, vitamin D levels, lipid profiles, Electrocardiogram (ECG) changes and echocardiography results, was completed during hospitalization.Results: Mean age in the case and control group was 63.26 Â± 10.76 and 61.22 Â± 10.71 years, respectively. The prevalence of diabetes and high blood pressure in the case group was 32% and 54% versus 10% and 8% in the control group, respectively. Overall, 70% and 18% of subjects were smokers in the control and case groups, respectively. Mean concentration of vitamin D in serum was 20.63 Â± 13.90 ng/mL, which was significantly lower than the control group with a mean concentration of 29.54 Â± 16.8 ng/mL (P-Value = 0.002). Finally, it was shown that for every one unit increase in vitamin D levels, the risk of acute coronary syndrome was reduced by 7% (P-Value = 0.005).Conclusions: The results of this study showed that the serum levels of vitamin D were significantly lower in patients with acute coronary syndrome compared to those without this disease.

We present a 65-year-old man who developed retrosternal compressive chest pain. A 12-lead electrocardiography demonstrated ST-segment elevation in leads II, III and aVF. Emergent coronary angiography showed significant thrombus in the distal portion of the left main coronary artery. Abdomino-pelvic computed tomography scan, which was performed the next day, confirmed a pancreatic mass with peritoneal seedings, compatible with peritoneal carcinomatosis. This case underscores the importance of malignancies that may lead to a catastrophic ST-elevation myocardial infarction due to a hypercoagulable state and following thrombosis in the left main coronary artery.

Publisher : International Journal of Cardiovascular Practice

The evaluation of left ventricular wall motion in Magnetic Resonance Imaging (MRI) clinical practice is based on a visual assessment of cine-MRI sequences. In fact, clinical interpreters (radiologists) proceed with a global visual evaluation of multiple cine-MRI sequences acquired in the three standard views. In addition, some functional parameters are quantified following a manual or a semi-automatic contouring of the myocardial borders. Although these parameters give information about the functional state of the left ventricle, they are not able to provide the location and the extent of wall motion abnormalities, which are associated with many cardiovascular diseases. In the past years, several approaches were developed to overcome the limitations of the classical evaluation techniques of left ventricular function. The aim of this article is to present an overview of the different methods and to summarize the relevant techniques based on myocardial contour detection and optical flow for regional assessment of left ventricular abnormalities.

Strategy to manage T-Wave Oversensing in a Biventricular ICD Akbarzadeh, Mohammad Ali; Namazi, Mohammad Hassan; Safi, Morteza; Sheibani, Mehdi
International Journal of Cardiovascular Practice Vol 2, No 2 (2017)
Publisher : International Journal of Cardiovascular Practice

T-wave oversensing is a relatively prevalent cause of intracardiac signals oversensing in patients with Implantable Cardioverter Defibrillator (ICD). Some of these oversensings are typically corrected with device reprogramming. If reprogramming fails to resolve the issue, invasive options such as repositioning the implanted lead may be necessary. We present a patient with dilated cardiomyopathy and intermittent T wave oversensing by a cardiac resynchronization therapy (CRT) that was managed by altering V-V timing.

Publisher : International Journal of Cardiovascular Practice

Introduction: There is little information about the relationship between hyperuricemia and contrast induced nephropathy. The present study aimed to evaluate the relationship between hyperuricemia and contrast induced nephropathy among patients, who had undergone coronary angiography.Methods: In the current study, 200 consecutive patients with coronary artery disease, who underwent coronary angiography in Modarres hospital, were enrolled. According to the available data, the upper limit normal level of uric acid was defined as 7 mg/dl in males and 6.5 mg/dl in females. By increasing level of serum creatinine to 0.5 mg/dl (or 25% enhancement) from basic level of creatinine during 48 hours of introduction of contrast agent, diagnosis of Contrast Induced Nephropathy (CIN) was established. The relationship between hyperuricemia and CIN was then assessed.Results: There is a significant difference between normouricemic patients and hyperuricemic patients, in aspect of weight (P = 0.011) and uric acid (P = 0.001); however, other quantitative and qualitative variables including age, volume of contract agent, creatinine level after angiography, hemoglobin level, gender, arterial access type, number of involved vessels, were insignificant between the two groups (P > 0.05). Moreover, as an essential finding, CIN was shown in 9% of normouricemic patients and 10% of hyperuricemic Â patients with no significant difference between the two groups (P = 0.6).Conclusions: Our study suggests that hyperuricemia may not significantly increase the rate of the contrast-induced nephropathy in patients, who had undergone angiography

Introduction: Nocturnal hypoxia is an important factor in increasing the risk of mortality in patients with chronic heart failure and is associated with atrial and ventricular arrhythmias. In addition, QT dispersion (QTd) is used as a prognostic sign in determining future malignant arrhythmias and sudden cardiac death. In the current study, we investigated the effect of nocturnal oxygen therapy (NOT) on electrocardiographic changes among patients with chronic heart failure.Methods: In this study, a consecutive of 154 patients (87 males and 67 females) known with chronic heart failure (EF â¤ 40%) were enrolled. The patients were administered NOT (oxygen flow of 2 L/min for 8 hours during sleeping). Electrocardiography was takenbefore and after the NOT, and RR interval, PR interval and QTd were measured each time.Results: The mean age of the participants was 61.3 Â± 11.4 years. Our results revealed significant reduction in QTd (55.8 Â± 7.5 vs. 61.4Â± 9.1 msec, P = 0.001) and heart rate (79.6 Â± 4.7 vs. 76.8 Â± 4.3, P = 0.001) in a patientâs electrocardiogram after NOT.Conclusions: In this study, NOT decreased heart rate and QTd in patients with chronic heart failure, but not PR interval, which could consequently decrease the risk of malignant arrhythmias and sudden cardiac death.

Biological Pacemakers â A Review Gunasekaran, Velvizhi; Selvaraj, Raja

Publisher : International Journal of Cardiovascular Practice

Slow heart rates, due to sinus node disease or atrioventricular conduction block, are a significant problem for many patients. Currently, these patients are treated with electronic pacemakers, which provide effective therapy, but are also associated with many problems. Use of biological pacemakers is an attractive solution to these problems. Approaches for the creation of such pacemakers include either the injection of cells that have pacemaker activity (cell-based approach) or modification of cells in the heart to induce pacemaker activity by delivering genes (gene-based approach). This article reviews the progress in the development of biological pacemakers.

Introduction: Cardiovascular surgeries are among the conventional surgeries aimed at increasing the survival rate and improving the quality of life of patients. This study aimed to evaluate the effect of cardiac rehabilitation on quality of life of patients undergoing Coronary artery bypass graft (CABG) surgery.Methods: This was a semi-experimental study performed on 160 patients undergoing CABG surgery. The rehabilitation program was carried out for 13 weeks (three sessions per week) in 40 sessions, six weeks after the CABG surgery. The MacNew standard questionnaire and the general health questionnaire (S-f 36) were completed before the beginning of rehabilitation sessions as well as after completion of these sessions by patients.Results: According to the results, the quality of life of patients significantly increased in the physical and emotional areas after the rehabilitation program. The results also indicated that there was a significant difference between various levels of research in the physical functioning variables, dysfunction due to physical health, dysfunction due to emotional health, energy/fatigue of individuals, emotional well-being, social functioning, pain, and general health.Conclusions: The present results indicated the improved quality of life of patients in all the areas after cardiac rehabilitation intervention, compared to before that. Therefore, paying more attention to cardiac rehabilitation is necessary due to its positive effects on increasing the quality of life of patients.

Introduction: Clinical decision support systems (CDSS) are computer systems designed to assist clinicians with patient-related decision making, such as diagnosis and treatment. CDSS have shown to improve both patient outcomes and cost of care.Methods: A multi-center observational prospective study was conducted. Ten physicians agreed to participate. Seventy-seven patients with high or very high cardiovascular risk were included. After using CDSS for dyslipidemia (HTE-DLPR) for a 3 months period, participants were asked to evaluate their experience with HTE-DLPR using a quality of experience questionnaire (QoE) tool for mHealth applications.Results: Total score on the QoE was 3.89 out of 5. The highest scores were received for precision, ease of use and content quality. The lowest scores were given to security, appearance and performance. Physicians were in strong agreement with the 1st HTEDLPR recommendation in 86.1% and the systemâs use was described as comfortablein 85% of cases. Users positively evaluated the development of a new version of HTEDLPR in the future receiving a total score of 4.25 out of 5.Conclusions: A CDSS for dyslipidemia (HTE-DLP) has been positively evaluated by physicians using QoE questionnaire.
