RESUMEN

Valvular heart disease contributes to a large burden of morbidity and mortality in the United States. During the last decade there has been a paradigm shift in the management of valve disease, primarily driven by the emergence of novel transcatheter technologies. In this article, the latest update of the American College of Cardiology/American Heart Association valve heart disease guidelines is reviewed.

RESUMEN

Objective: To survey individuals who tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) at 1 of 4 Trinity Health of New England drive-through testing centers to assess their demographic information, hospitalization rate, preexisting conditions, possible routes of exposures, duration of symptoms, and subsequent household infections of healthcare workers (HCWs) when compared to non-HCWs. Methods: Data were collected via a telephone survey using a standardized script. Between March 1, 2020 and June 17, 2020, 28,903 people were tested at 4 Connecticut drive-through testing centers. Individuals who tested positive between March 16 and April 21, 2020 were randomly contacted. Of those individuals, 100 people agreed to complete the survey. Bivariate analysis and logistic regression were performed. Results: HCWs comprised 46% of the 100 survey respondents during the study period. Similarly, HCWs comprised 42.1% of all individuals who tested positive and listed an employer between March 1 and June 17, 2020. HCWs reported a longer duration of symptoms (17.39 vs 13.44 days) and were more likely to report work as their route of exposure (80.4% vs 27.8%) than non-HCWs. Conclusions: HCWs may face a disproportionate risk of contracting COVID-19 and self-report a longer duration of symptoms than the general public. The data suggest a need for an increased recovery time away from work than is currently recommended by the Centers for Disease Control and Prevention, as well as an increase in infection precautions for HCWs.

RESUMEN

INTRODUCTION: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has spread rapidly since December 2019, resulting in a pandemic that has, as of May 24, 2020, yielded over 5.3 million confirmed cases and over 340,000 deaths. As businesses move to safely reopen and frontline healthcare workers (HCW) continue to face this crisis, it is essential that health officials know who in the population is at the greatest risk of mortality if hospitalized and, therefore, has the greatest need to protect themselves from being infected. We examined the factors that increase the risk of mortality among hospitalized COVID-19 patients. METHODS: This was a retrospective cohort study including confirmed COVID-19 patients admitted to the four Trinity Health of New England hospitals (THONE) in Connecticut and Massachusetts who either died or were discharged between March 1-April 22, 2020. Demographics, comorbidities, and outcomes of care were extracted from the electronic health record. A model of in-hospital mortality was made using a generalized linear model with binomial distribution and log link. RESULTS: The analysis included 346 patients: 229 discharged and 117 deceased. The likelihood of in-hospital mortality was increased for patients who were aged 60 or older (relative risk [RR] = 2.873; 95% confidence interval [CI], 1.733-4.764; p = <0.001), had diabetes (RR = 1.432; 95% CI,1.068-1.921; p = 0.016), or had chronic obstructive pulmonary disease (COPD) (RR = 1.410; 95% CI, 1.058-1.878; p = 0.019). Hyperlipidemia had a protective effect, reducing the likelihood of mortality (RR = 0.745; 95% CI, 0.568-0.975; p = 0.032). Sensitivity and specificity of the model were 51.4% and 88.4%, respectively. CONCLUSIONS: Being age 60 or older or having a history of diabetes or COPD are the most useful risk factors associated with mortality in hospitalized COVID-19 patients. As states ease stay-at-home orders, risk factors of severe disease can be used to identify those more likely to have worse outcomes if infected and hospitalized and, therefore, who in particular should continue to follow public health guidelines for avoiding infection: stay home if possible; practice physical distancing; and wear a facemask.

RESUMEN

Coronary embolism is an uncommon mechanism of myocardial infarction in comparison with atherosclerotic plaque rupture. We present a unique case of an anterior ST elevation myocardial infarction as a result of coronary embolism, the source of which appears to be calcific debris from mitral annular calcification (MAC). Although embolic phenomena in the setting of MAC has been documented previously, particularly in the setting of acute ischemic stroke, to our knowledge this is the first reported case in the literature where MAC alone appears to have resulted in a coronary embolic event. .

RESUMEN

Although several risk factors are associated with spontaneous coronary artery dissection, strenuous activity is an uncommon risk factor for women. We report a case of a patient who developed spontaneous coronary artery dissection shortly after starting F45, a highly strenuous fitness program. As high-intensity exercise regimens become more mainstream, clinicians should more readily consider spontaneous coronary artery dissection in young patients with history of recent strenuous activity when presenting with symptoms concerning for acute coronary syndrome.

RESUMEN

In the pre-direct-acting antiviral era, hepatitis C virus (HCV) treatments were complex and largely managed by hepatologists, gastroenterologists, and infectious disease physicians. As direct-acting antivirals have driven up demand for treatment, the relative scarcity of these specialists has created a bottleneck effect, resulting in only a fraction of HCV-infected individuals offered treatment. The San Francisco Health Network is a safety net system of care. Its intervention was designed to be sustainable and scalable; with minimal time commitments for training providers, primary care-based HCV treatment increased 3-fold in a period of just over 3 years.

RESUMEN

BACKGROUND: Initiated in 2016, End Hep C SF is a comprehensive initiative to eliminate hepatitis C (HCV) infection in San Francisco. The introduction of direct-acting antivirals to treat and cure HCV provides an opportunity for elimination. To properly measure progress, an estimate of baseline HCV prevalence, and of the number of people in various subpopulations with active HCV infection, is required to target and measure the impact of interventions. Our analysis was designed to incorporate multiple relevant data sources and estimate HCV burden for the San Francisco population as a whole, including specific key populations at higher risk of infection. METHODS: Our estimates are based on triangulation of data found in case registries, medical records, observational studies, and published literature from 2010 through 2017. We examined subpopulations based on sex, age and/or HCV risk group. When multiple sources of data were available for subpopulation estimates, we calculated a weighted average using inverse variance weighting. Credible ranges (CRs) were derived from 95% confidence intervals of population size and prevalence estimates. RESULTS: We estimate that 21,758 residents of San Francisco are HCV seropositive (CR: 10,274-42,067), representing an overall seroprevalence of 2.5% (CR: 1.2%- 4.9%). Of these, 16,408 are estimated to be viremic (CR: 6,505-37,407), though this estimate includes treated cases; up to 12,257 of these (CR: 2,354-33,256) are people who are untreated and infectious. People who injected drugs in the last year represent 67.9% of viremic HCV infections. CONCLUSIONS: We estimated approximately 7,400 (51%) more HCV seropositive cases than are included in San Francisco's HCV surveillance case registry. Our estimate provides a useful baseline against which the impact of End Hep C SF can be measured.

RESUMEN

BACKGROUND: The results of mitral valve repair operations conducted at community hospitals in rural states are not well studied or reported in the literature. METHODS: We retrospectively assessed consecutive patients who underwent isolated mitral valve repair operations performed by a single experienced cardiothoracic surgeon at a large community hospital from May 1, 2006 - April 30, 2010. Patients were monitored for up to three years (average 2.2 years) following surgery for a variety of surgical variables, including morbidity, mortality, and serial two-dimensional transthoracic echocardiographic findings. Comparisons were made with the Society of Thoracic Surgeons Adult Cardiac Surgery Database (ACSD). RESULTS: Sixty-three consecutive patients underwent isolated complex mitral repair operations. Echocardiographic and morbidity data demonstrated successful outcomes, with no operative mortality and a single cardiac-related death within three years postoperatively. Other variables, especially those that relate to post-repair outcomes, showed no significant differences between our patients and comparison data from the ASCD. CONCLUSIONS: Our study demonstrates equivalent risks and outcomes for complex mitral valve repair performed in a community hospital setting as those found in a national database. The appropriate institutional setting for performing highly complex procedures has substantial implications for health policy, especially regarding access and quality issues.

RESUMEN

Patients with hepatic hemangiomas have been known to have high-output heart failure as a result of left-to-right arteriovenous shunting. We report a patient with a hepatic hemangioma that presented with high-output heart failure with hypoxia on exertion. After embolization of the hemangioma, the patient's hypoxia resolved and ejection fraction improved. In the absence of cardiopulmonary pathophysiology, we presume that our patient's hemangioma was causing a right-to-left shunt as opposed to an expected left-to-right shunt.
