Abstract Background and Objective: Young women with STEMI fare worse than men. Data for such patients in particular South Asians (SA) is sparse. Therefore, this study explored the common risk factors, angiographic features and outcomes in these patients. Methods: It was a cross-sectional study done from 2013-2019 on female STEMI patients <45 years who underwent Coronary Catheterization and revascularization at Aga Khan University Hospital, Pakistan. Subjects with revascularizations or MI were excluded. with Anterior STEMI and PCI was the commonest mode of revascularization. Majority, (82%, n=19) had Single vessel disease with lesions in Left Anterior Descending (LAD). Proximal LAD lesions required stents 27.6 (+10) mm long and 3.0 (+0.4) mm wide on average. Mortality was seen in one patient. A third of patients (n=9) presented with heart failure whereas a quarter (n=7) with hypotension. A minority required mechanical ventilation, Cardiopulmonary resuscitation or temporary pacemaker. Conclusions: STEMI is relatively uncommon in young SA women. Associated risk factors are Diabetes, obesity and positive family history. SVCAD with LAD involvement is the most common pattern. Rates of mortality, heart failure admissions or repeat revascularizations are minimal.","PeriodicalId":72523,"journal":{"name":"Cardiology and cardiovascular medicine","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69346216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the acute setting, however, the administration in patients with left ventricular failure is seen controversial, specifically as a potential negative inotropic effect and antagonism of the applied inotropic agents may possibly worsen the clinical situation of the patient. Recently the super selective short acting β 1 -AR Landiolol has been used in patients with acute left ventricular decompensation and, in conjunction with inotropic agents, did not deteriorate but improved the cardiovascular status of the patients. The present work summarizes the theories how a β 1 -AR blocker may act additive to inotropic agents in patients with acute cardiac failure. Specifically , receptor bindings models are presented in which the β 1 -AR blocker Landiolol can induce a positive inotropic response. These models are based on the fact that in patients with left ventricular dysfunction the plasma levels of catecholamines exceed their dissociation constants and rather decrease than improve the inotropic response due to negative cooperativity at the occupied receptor dimers. Low distinct Landiolol concentrations then reduce the negative cooperation and shift the receptor response curve into a more positive inotropic range. This article may thus help to minimise the reservations to the treatment of acute left ventricular deterioration with the super selective beta blocker Landiolol and positive inotropic agents. More so as the dose range calculated for Landiolol in these models and the one’s used in the intensive care setting prove to be identical.","PeriodicalId":72523,"journal":{"name":"Cardiology and cardiovascular medicine","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69346704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Commonly, a negative D-dimer assay is accepted for ruling out PE; however, there have been cases such as this case that challenge current practice. Case presentation: This case report presents an 83-year-old female with sudden onset shortness of breath associated with low oxygen saturation on the physical exam. Initial workup revealed elevated levels of troponin-T and pro-B-type natriuretic peptide with preliminary normal D-dimer assay. At the start, the patient managed as Right Ventricular (RV) infarction with remarkable findings of RV dysfunction and pressure overload in transthoracic echocardiogram. Eventually chest CT angiogram documented extensive bilateral pulmonary emboli (PE), and interestingly, D-dimer became positive 5 days after the diagnosis of PE.

[ISSN 2572-9292] 302 Conclusions: This case report is a rare case of initial negative D-dimer in the setting of extensive bilateral PE which caused right ventricular infarction. The literature review demonstrated only a few cases of PE in the setting of negative D-dimer. This unusual clinical scenario presents a diagnostic challenge in patients with low or moderate clinical probability for PE; even some current practices indicate stopping further diagnostic work-up if the D-dimer is negative in these groups. To mitigate negative outcomes in patients with low or moderate clinical probability, other strategies have been proposed to make an early diagnosis of PE such as triple combination modalities; however, they require additional analysis and consideration before they can be routinely recommended.","PeriodicalId":72523,"journal":{"name":"Cardiology and cardiovascular medicine","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69346598","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Residency Program Committee (RPC) for the Cardiology training program at Dalhousie University in Halifax, Canada addressed the Transition to Practice stage by approving a trial of adjusting the resident call responsibilities to reflect the transition to CBD curriculum. The goal of this adjustment was three-fold: i. Gradually increase accountability of the senior cardiology resident as they transition to practice; ii. Address a gap in training that allows the senior resident to have a gradual transition to the role of a practicing cardiologist while on call; iii. Allows further evolution of skills and abilities.\u0000Methods\u0000\u0000A survey was administered to the practitioners involved in this competency-based change to the call responsibilities. Surveys were distributed to the final year Cardiology Residents, Staff Cardiologists, and Senior Internal Medicine residents to assess their experience and opinions of the current, competency-based change of the on-call curriculum. The survey consisted of eleven questions, of which, four were assessed on a Likert scale and 3 were yes/no questions.\u0000Results\u0000\u0000Four PGY6 cardiology residents, five senior internal medicine residents and eleven staff cardiologists completed the survey. Amongst those who completed the survey there was agreement that the change to the on-call responsibilities improved cardiology residents’ skills, accountability and preparedness to practice.

While recent studies have identified that there is an increase in structural injury to the nervous system in critically ill COVID-19 patients, there is little known about the relationship of COVID-19 neurological damage to the systemic inflammatory diseases also observed in COVID-19 patients. The purpose of this pilot observational study was to examine the relationships between serum neurofilament light protein (NfL, a measure of neuronal injury) and co-morbid cardiovascular disease (CVD) and neurological complications in COVID-19 positive patients admitted to the intensive care unit (ICU). In this observational study of one-hundred patients who were admitted to the ICU in Tucson, Arizona between April and August 2020, 89 were positive for COVID-19 (COVID-pos) and 11 was COVID-negative (COVID-neg). A healthy control group (n=8) was examined for comparison. The primary outcomes and measures were subject demographics, serum NfL, presence and extent of CVD, diabetes, sequential organ failure assessment score (SOFA), presence of neurological complications, and blood chemistry panel data. COVID-pos patients in the ICU had significantly higher mean levels of Nfl (229.6 ± 163 pg/ml) compared to COVID-neg ICU patients (19.3 ± 5.6 pg/ml), Welch's t-test, p =.01 and healthy controls (12.3 ± 3.1 pg/ml), Welch's t-test p =.005. Levels of Nfl in COVID-pos ICU patients were significantly higher in patients with concomitant CVD and diabetes (n=35, log Nfl 1.6±.09), and correlated with higher SOFA scores (r=.5, p =.001). These findings suggest that in severe COVID-19 disease, the central neuronal and axonal damage in these patients may be driven, in part, by the level of systemic cardiovascular disease and peripheral inflammation. Understanding the contributions of systemic inflammatory disease to central neurological degeneration in these COVID-19 survivors will be important to the design of interventional therapies to prevent long-term neurological and cognitive dysfunction.</p>","PeriodicalId":72523,"journal":{"name":"Cardiology and cardiovascular medicine","volume":"5 5","pages":"551-565"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8547787/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10105304","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous predictors may not accurately reflect cardiac dyssynchrony. It was hypothesized that the spatially and temporary continuous information of the whole endocardium is required when the mechanical dyssynchrony is assessed using echocardiography. This study aimed to examine differences in the locus of the centroid of the left ventricle between abnormal and normal wall motion. MethodsTwenty-seven patients with dilated cardiomyopathy (left ventricular ejection fraction [LVEF]: 43±7%) and 45 old myocardial infarction patients with aneurysm (LVEF: 38±11%) were compared with 188 individuals with normal wall motions (LVEF: 61±5%). In an off-line system, the border of the endocardium was defined for each coordinate via the two-dimensional speckle tracking method. The centroid of the three-dimensional left ventricle was defined as the central point between both centroids calculated from four- and two-chamber images using an original application. ResultsThe locus of the centroid of the left ventricle in the normal wall motion group showed a horizontally inverted β shape, whereas this shape was absent in the other groups. When corrected by left ventricular end-systolic volume, the total and each directional length of the locus of the centroid of the left ventricle in the abnormal wall motion groups were clearly reduced compared with those recorded in the normal wall motion group. The acceleration of the centroid was also reduced in the abnormal wall motion groups. Multiple regression analysis with a stepwise method revealed a corrected antero-posterior shift of the centroid of left ventricle by left ventricular end-systolic volume and N-terminal pro-brain natriuretic peptide, which strongly correlated with the LVEF (adjusted R2: 0.6818, p≤2.2e-16).ConclusionUse of the locus of the centroid of the left ventricle provides novel insight into the evaluation of abnormal left ventricular contractions.
