  • AN EASY AFFORDABLE STATISTICAL AND ECONOMIC (EASE) APPROACH TO AVOID UNNECESSARY AND EXPENSIVE EXAMS TO MONITOR PATIENTS WITH SMALL AAA

    Abdominal Aortic Aneurysm (AAA) is a localized enlargement of the abdominal aorta, such that the diameter exceeds 30 mm. AAA is a progressive growth leading to rupture, with high risk of mortality, therefore elective surgical repair is indicated when AAA diamenter is >55 mm. Screening programs, that use morphological imaging, have been developed internationally with the aim of detecting AAA before rupture with important limitations in term of cost and benefit for patients. Furthermore, different biochemical markers have been proposed to monitor AAA progression to overcome the above-mentioned limitations but none of them is used in the clinical practice. In fact, most of the biomarkers proposed are expensive and not feasible in the majority of laboratories. Combining different methodologies coming from Statistics and Operational Research fields, we developed an algorithm able to assess the importance of common biomarkers, requested in the clinical practice to evaluate the health of patient, and therefore no exams are required. Furthermore, we develop an Easy, Affordable Statistics and Economic (EASE) model able to identify if the AAA remain below the cut off for surgical repair. This prediction can provide guidance to how closely the patient’s abdominal aorta should be monitored avoiding additional and expensive exams.

  • LEFT VENTRICULAR LEAD IMPLANTATION FOR DETECTION OF VENTRICULAR ARRHYTHMIAS IN PATIENT WITH IMPLANTABLE CARDIOVERTER DEFIBRILLATOR AND LOW R WAVE IN RIGHT VENTRICLE

    Dilated cardiomyopathy (DCM) is a disease characterised as left ventricular (LV) or biventricular dilatation with impaired systolic function. Regardless of underlying cause patients with DCM have a propensity to ventricular arrhythmias and sudden cardiac death. Implantable Cardioverter Defibrillator (ICD) implantation for these patients results in significant reduction of sudden cardiac death [1-3]. ICD devices may be limited by right ventricle (RV) sensing dysfunction with low RV sensing amplitude. We present a clinical case of patient with DCM, implanted ICD and low R wave sensing on RV lead.

  • ARSENIC SPECIES BINDING PROTEINS IN CARDIOVASCULAR TISSUES FROM CARDIAC PATIENTS OF CHILE

    The intracellular As-protein binding in cytosol and methanol–water extract of the auricle and saphene tissues of As impacted people was evaluated by bidimensional size exclusion FPLC-UV-ICP-MS. The fractionation of cytosol using Superdex, Phenomenex and MonoQ HR 5/5 columns, shows that As is distributed in a wide range of contiguous fractions of each column, being 8, 25, 50 % the percentages of As in the collected fractions, respectively. In the methanol: water extracts a similar study than performed with the cytosol using preparative gel chromatography on Sephadex G-75 and Shephadex G-100 columns and the MonoQ HR 5/5 anion protein exchange was carried out.

  • THE RELATIONSHIP BETWEEN ADMINISTRATIVE FACTORS AND EFFECTIVENESS OF ST-SEGMENT ELEVATION MYOCARDIAL INFARCTION REFERRAL SYSTEM AMONG THAI HOSPITALS

    Background: This descriptive study aimed to study the relationship between administrative factors and the effectiveness of the referral system of patients with acute ischemic heart disease in Thai hospitals. Materials and methods: The target population was 1,180 hospitals that serving heart disease in Thailand. Data were collected by using a questionnaire. A total of 1,022 response data were obtained. Administrative factors were analyzed using descriptive statistics, and the relationship was analyzed using multiple regression analysis (MRA) methods. Results: The study showed that the administrative factors which consisted of personnel, finance, supporting, and management factors had overall average readiness at a high level (x̄ = 3.34, S.D. = 0.27). Except budget sufficiency was at a low level (x̄ = 2.43, S.D. = 0.43). All factors were related to the mortality rate significantly, as follows: management factor (Adjusted R2 = 0.433), personnel factor (Adjusted R2 = 0.231), supporting factor (Adjusted R2 = 0.092) and financial factor (Adjusted R2 = 0.035). All factors were also significantly related to the timely cardiac catheterization rate, as follows: management factor (Adjusted R2 = 0.442), personnel factor (Adjusted R2 = 0.244), supporting factor (Adjusted R2 = 0.212) and financial factor (Adjusted R2 = 0.091). Conclusion: Thai Ministry of Public Health should provide adequate support for administrative factors, especially in terms of management, personnel, supporting factors, and budget sufficiency.

Comparing calcified plaque and vulnerable plaque, mixed plaque and vulnerable plaque,there is a significant differences ( p < 0.01) while hs-CRP and IL-6 are as the indicator. Mahalanobis distance discrimination method has a discrimination accuracy of 91.83 % for the group wrih susceptible factors only. Conclusion: The model of predicting the extent of coronary artery calcification by multiple linear regression has high reliability. Vulnerable plaques can be distinguished from plaques of other properties efficiently using Mahalanobis distance discrimination method.

  • ROLE OF MESENCHYMAL STEM CELLS IN CARDIOVASCULAR DISEASE

    In recent years, globally there is an incredible boost in stem cell research has kindled the expectations of both patients and physicians. Mesenchymal stem cells (MSCs) seem to represent a future powerful tool in regenerative medicine, owing to their availability, ease of manipulation, and therapeutic potential, therefore they are particularly important in medical research. Mesenchymal stem cells (MSCs) are capable self-renewing, multipotent progenitor cells with multilineage potential to differentiate into cell types, such as adipocytes, cardiomyocytes, endothelial cells and vascular smooth muscle cells, although the relative contribution of trilineage differentiation and paracrine effectors on cardiac repair. MSCs shows to have the beneficial effects of MSC-based therapies offers most attractive options to treatment of wide range of diseases from cartilage defects to cardiac disorders. Cardiovascular diseases (CVDs) are an important cause of death and disease worldwide. Because injured cardiac tissue cannot be repaired itself, it is urgent to develop other alternate therapies. Stem cells can be differentiated into cardiomyocytes, endothelial cells, and vascular smooth muscle cells for the treatment of CVDs. In addition to cardiac stem cells, mesenchymal stem cells represent another multipotent cell population in the heart; these cells are located in regions near pericytes and exhibit regenerative, angiogenic, antiapoptotic, and immunosuppressive properties.

  • Understanding Health Professionals about Preservation of Silence in the Intensive Care Unit During the Post-Heart Surgery Surgery: a Systematic Review

    Introduction: Through studies in the scientific literature about the measurement of sounds in the Intensive Care Unit environment, it is clear that the noise, continuous sound of equipment and those caused by the health team itself is excessive and above 85dB (decibels), favors increased sensitivity of patients to pain, irritation, post-traumatic stress and may cause psychomotor agitation, delirium, changes in heart rate and sleep. A peaceful environment can bring countless benefits to restoring the health of patients, as well as reducing the stress of professionals. Objective: To analyze some research and studies published in Brazil about the noise in an Intensive Care Unit and the perception that professionals have about this topic. Methods: A systematic literature review was performed with electronic search of articles indexed in PePSIC and SciELO databases, published from 2009 to 2019, in which the inclusion and exclusion criteria were considered. Results: indicate that the noise in this type of place often presents with an oscillating intensity of moderate to intense. It is verified that there is from the professionals a certain level of understanding of the existence of noise in the ICU. Considerations: Despite the finding by professionals about noise, it is also observed that there are few current publications about the awareness of health professionals regarding the importance of preserving a quieter environment and criteria that reinforce effective humanization interventions during the study. postoperative period of cardiac surgery in this type of environment.

  • Homeopathy treatment for Heart Diseases

    World records that two out of six individuals will bite the dust from coronary illness and six out of ten men over age 30 may have indications of coronary illness. The redeeming quality, be that as it may, is heart issues are sensible; furthermore, they can be forestalled, or even switched, with ideal, proficient clinical treatment. A huge number of hazard factors assumes a job in the improvement of coronary illness cigarette, smoking, physical idleness, stress, weight, high blood cholesterol, (hypertension) and diabetes. These components are controllable and not controllable. The most ideal way one can decrease the danger of coronary illness is by limiting, or dodging, the hazard factors-quitting any pretense of smoking, keeping away from liquor, confining salt use, constraining calorie consumption, practicing normally, diminishing enthusiastic pressure, getting observed and researched for hypertension, raised fat, cholesterol and different elements. The initial step, obviously, ought to be meant to bring down one’s hypertension the higher the circulatory strain, the more noteworthy is the danger of coronary episode, stroke and kidney illness. All the more significantly, if any of one’s nearby family members have had hypertension, at an early age, such people ought to be encouraged to have their circulatory strain checked all the time. However it can be miraculously treated by homeopathy
