Abstract:

Background: The association between PM2.5 levels and adverse cardiovascular health outcomes is well-known. Several studies that focused on hospital admissions for cardiovascular diseases showed that increase in PM2.5 concentration was associated with an increase in hospital admissions for ischemic heart disease, arrhythmias and heart failure.

Methods: We examined the impact of daily concentrations of Fine Particulate Matter (PM2.5) on admission to all patients with a diagnosis of cardiovascular disease in all hospitals that has wards, heart and CCU, during the 2011-2012 (March 2011 to February 2012) in Isfahan, using a case-crossover study design. Data were received on PM2.5 concentrations for each hour in a station and were obtained for temperature and humidity in all the weather stations. The analysis was performed using SAS 9.2 software.

Results: There were 16690 hospital admissions for cardiovascular diseases. The average age of the subjects was 59.63±18.87 years. The mean concentration of PM2.5 was 56.64±28.83 µg/m³ during the study period. The effect of PM2.5 on the risk of hospitalization for cardiovascular disease was significant and daily concentrations of PM2.5 is directly related with cardiovascular disease hospitalization rate (OR=1.064, CI: 1.038-1.090). Maximum of the association after adjustment for O3 (OR=1.086, CI: 1.051-1.122). Adjustment for PM10 was not significant (OR=1.014, CI: 0.986-1.043).

Conclusion: this study provides evidence that higher levels of PM2.5 increase the risk of hospital admissions for cardiovascular disease during the 2011–2012 in Isfahan. Also, the level of pollutant is higher than the WHO standard.

Abstract:

Background: Calcium activated Cl⁻ current (I_Cl(Ca)) mediated by TMEM16A and/or Bestrophin-3 may contribute to cardiac arrhythmias. Our goal was to study the I_Cl(Ca) profile during an actual ventricular action potential (AP) under normal calcium cycling as well as in case of altered intracellular calcium concentration ([Ca²⁺]_i). The expression of TMEM16A and/or Bestrophin-3 in canine and human left ventricular myocytes was examined.

Methods: Whole-cell configuration of the patch-clamp technique and action potential voltage-clamp were used to monitor I_Cl(Ca), detected as 9‑anthracene carboxylic acid (9‑AC)-sensitive current. FURA-2-AM dye was used to measure [Ca²⁺]_i. Expression and cellular localization of Cav1.2, Bestrophin-3 and TMEM16A was analyzed with immunocytochemistry and confocal microscopy.

Results: Under AP voltage-clamp conditions the profile of I_Cl(Ca) contained an early fast outward (1.62±0.06 A/F) and a late inward component (-0.16±0.02 A/F). Both components were reduced by ryanodine (1.05±0.03 A/F; -0.07±0.03 A/F), while fully abolished by BAPTA, but not EGTA (1.17±0.09 A/F; −0.13±0.02 A/F). Setting [Ca²⁺]_i to 1.1 µM decreased I_Cl(Ca), while application of Bay K8644, isoproterenol increased the amplitude of I_Cl(Ca). Both L-type Ca²⁺ current and I_Cl(Ca) were eliminated by nisoldipine. TMEM16A and Bestrophin-3 showed strong co-localization with one another and also with Ca_v1.2 channels both canine myocytes and human ventricular myocardium.

Conclusions: Activation of I_Cl(Ca) in canine ventricular cells requires calcium entry through neighboring L-type Ca²⁺ channels and is only augmented by SR Ca²⁺-release. Substantial activation of I_Cl(Ca) requires high Ca²⁺ in the dyadic clefts which can be effectively buffered by BAPTA, but not EGTA.

Ala Ashour, PhD, RN. Professional experience: more than fifteen years of professional experience in critical care nursing and academia. Education: Bachelor’s and master’s degree in nursing (critical care nursing) from Jordan University of Science and Technology and PhD in 2014 from University of Ulster, Belfast, United Kingdom. Currently: Assistant professor in nursing, Faculty of Nursing at Hashemite University-Jordan. Research interest:  cardiac care nursing, critical care nursing, refugees health, and primary and secondary prevention particularly for patients with coronary artery disease.

Abstract:

Statement of the Problem: Coronary heart disease (CHD) is a major health problem and the leading cause of death in Jordan. As a result of advances in technology and treatment for patients with CHD, the number of patients undergoing percutaneous coronary intervention (PCI) has increased, and patients are being discharged sooner than ever before. The purpose of this study is to explore and prioritize the actual learning needs of Jordanian patients after undergone PCI, and to examine the relationships between patients’ learning needs and their illness perceptions in order to design nurse-led education programs. Methodology: A descriptive, correlational design was used. Data were collected from 208 PCI patients before their discharge from King Abdullah University Hospital and Prince Hamzah Hospital. The Percutaneous Coronary Intervention Learning Needs Inventory (PCILNI), was developed to assess patients’ learning needs 24-48 hours before their discharge from the hospital, and the Illness Perceptions questionnaire was used to assess their illness perception. Findings: The results showed that patients need a high amount of information. The information about immediate post-procedural knowledge category was indicated to be the most valued by PCI patients (Mean 4.42). The highest rated items were symptoms management, discharge medication, post-procedural medications and complications. There was a significant negative correlation between total learning needs and personal and treatment control respectively (P= 0.012, P= 0.028); Patients who perceived low levels of personal and treatment control over illness, and tend to need more educational knowledge. Conclusion & Significance: Patients undergoing PCI have high and different information needs. These findings would help to develop nurse-led education programs based on actual patient’s needs and their illness perception, which will facilitate the recovery of patients after undergone PCI.

Yin Kang has been trained in clinical cardiac pacing and electrophysiology under the direction of Professor Hua Wei for many years. During her doctoral study in Chinese Academy of Medical Sciences and Peking Union Medical College, she systemically reviewed the patients who had been implanted an ICD at Fuwai Hospital in the nearly recent 30 years with the guidance of Professor Hua Wei. After hard work of follow-up and thorough study of patients with arrhythmic right ventricular cardiomyopathy (ARVC) and an ICD, she presented the effectiveness of ICDs in prevention of sudden cardiac death, and the prevalence, treatment measures and prognosis of ICD electrical storm in those patients. Her research provides reference for the treatment and further investigation of this kind of patients.

Abstract:

Background: Implantable cardioverter defibrillator (ICD) is the most important management for prevention of sudden cardiac death (SCD) in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC). However, some patients may receive multiple ICD therapies in a short period, a condition referred as “electrical storm” (ES). Objectives: This study aimed to determine the prevalence, therapeutic options, and prognostic implications of ES in ARVC patients with an ICD. Methods: We retrospectively analyzed the baseline and follow-up data of 39 ARVC patients with an ICD. ES was defined as three or more separated episodes of ventricular tachycardia or ventricular fibrillation (VT/VF) within a 24-hour period. Results: During a median follow-up of 49 months (range 6–225), 12 of 39 (31%) patients suffered at least one episode of ES. The interval between the first ES and the initial ICD implantation ranged from 1 month to 109 months, and ES was the first ICD discharge in three patients. The median number of VT/VF events per ES was four (range 3–39). Five patients experienced 20 episodes of ES that were treated by antitachycardia pacing only, while the other seven patients suffered shock therapies during ES. In three patients, ES required emergency hospitalization, and the repeatedly occurred VT/VF was finally subsided by intravenous amiodarone. There was no significant difference in actual survival between patients with and without such an event. Conclusions: ES is not rare in ARVC patients with an ICD for prevention of SCD, but it does not independently confer increased mortality. Intravenous amiodarone is effective in management of ES when VT/VF repeatedly occurred.

Abstract:

This study elucidates the surgical management of Heart disease in a tertiary care center in Southern India. A total of 139 cases of heart disease were surgically managed from May 2015 to July 2017 at Stanley Medical College. In this, the average age of patient population is 43.94 with 43.16 % in age group of 30- 44. Male to female ratio is (1.13: 1).Both valve replacement and CABGs are performed. Of the total cases, 83 patients underwent valve replacement surgeries, 41 patients underwent CABG. In congenital cardiac disease a total of 13 cases were done with ASD (OS) being most common. Mitral valve disease secondary to rheumatic pathology is the most common valvular disease. Of the 83 patients who underwent valvular replacement, MVR (55) is the most common followed by MVR with /devega tricuspid annuloplasty (13), AVR and DVR. Of the 41 patients who underwent CABG, LIMA was harvested in 9 cases and RIMA in 1 case. All cases were done under cardiopulmonary bypass. The increased number of rheumatic heart disease compared to coronary heart disease establishes the still widely prevalent problem of rheumatic heart disease in this part of the world.
