Electrocardiographic Findings in Female Professional Basketball Athletes.

Importance: Previous studies of professional basketball athletes have characterized manifestations of athletic remodeling by echocardiography and electrocardiography (ECG) in males and echocardiography in females. There is a paucity of female, basketball-specific ECG data. Objective: To generate reference range ECG data for female professional basketball athletes. Design, Setting, and Participants: This is a cross-sectional study of ECGs performed on female professional basketball athletes. The Women's National Basketball Association mandates annual preseason ECGs and echocardiograms for each athlete and has partnered with Columbia University Irving Medical Center to annually review these studies. Data for this study were collected during preseason ECG and echocardiography cardiac screening between April and May 2022. Data analysis was performed between February and July 2023. Exposure: Athlete ECGs and echocardiograms were sent to Columbia University Irving Medical Center for core lab analysis. Main Outcomes and Measures: Quantitative ECG variables were measured. ECG data were qualitatively analyzed for training-related and abnormal findings using the International Recommendations for Electrocardiographic Interpretation in Athletes. Findings from ECGs were compared with corresponding echocardiographic data. Results: There were a total of 173 athletes (mean [SD] age 26.5 [4.1] years; mean [SD] height, 183.4 [9.1] cm; mean [SD] body surface area, 2.0 [0.2] m2), including 129 Black athletes (74.5%) and 40 White athletes (23.1%). By international criteria, 136 athletes (78.6%) had training-related ECG changes and 8 athletes (4.6%) had abnormal ECG findings. Among athletes with at least 1 training-related ECG finding, left ventricular structural adaptations associated with athletic remodeling were present in 64 athletes (47.1%). Increased relative wall thickness, reflecting concentric left ventricular geometry, was more prevalent in athletes with the repolarization variant demonstrating convex ST elevation combined with T-wave inversions in leads V1 to V4 (6 of 12 athletes [50.0%]) than in athletes with early repolarization (5 of 42 athletes [11.9%]) (odds ratio, 7.40; 95% CI, 1.71-32.09; P = .01). Abnormal ECG findings included T-wave inversions (3 athletes [1.7%]), Q waves (2 athletes [1.2%]), prolonged QTc interval (2 athletes [1.2%]), and frequent premature ventricular contractions (1 athlete [0.6%]). Conclusions and Relevance: This cross-sectional study provides reference ECG data for elite female basketball athletes. International criteria-defined training-related findings were common, whereas abnormal ECG findings were rare in this athlete group. These reference data may assist basketball programs and health care professionals using ECGs in screening for female athletes and may be used as a stimulus for future female-specific ECG inquiries.

Communication approaches to enhance patient motivation and adherence in cardiovascular disease prevention.

Preventive cardiology visits have traditionally focused on educating patients about disease risk factors and the need to avoid and manage them through lifestyle changes and medications. However, long-term patient adherence to the recommended interventions remains a key unmet need. In this review we discuss the rationale and potential benefits of a paradigm shift in the clinician-patient encounter, from focusing on education to explicitly discussing key drivers of individual motivation. This includes the emotional, psychological, and economic mindset that patients bring to their health decisions. Five communication approaches are proposed that progress clinician-patient preventive cardiology conversations, from provision of information to addressing values and priorities such as common health concerns, love for the family, desire of social recognition, financial stressors, and desire to receive personalized advice. Although further research is needed, these approaches may facilitate developing deeper, more effective bonds with patients, enhance adherence to recommendations and ultimately, improve cardiovascular outcomes.

Opportunities to improve cardiovascular health in the new American workplace.

Adult working-class Americans spend on average 50% of their workday awake time at their jobs. The vast majority of these jobs involve mostly physically inactive tasks and frequent exposure to unhealthy food options. Traditionally, the workplace has been a challenging environment for cardiovascular prevention, where cardiovascular guidelines have had limited implementation. Despite the impact that unhealthy lifestyles at the workplace may have on the cardiovascular health of U.S. workers, there is currently no policy in place aimed at improving this. In this review, we discuss recent evidence on the prevalence of physical inactivity among Americans, with a special focus on the time spent at the workplace; and the invaluable opportunity that workplace-based lifestyle interventions may represent for improving the prevention of cardiovascular disease. We describe the current regulatory context, the key stakeholders involved, and present specific, guideline-inspired initiatives to be considered by both Congress and employers to improve the "cardiovascular safety" of US jobs. Additionally, we discuss how the COVID-19 pandemic has forever altered the workplace, and what lessons can be taken from this experience and applied to cardiovascular disease prevention in the new American workplace. For many Americans, long sitting hours at their job represent a risk to their cardiovascular health. We discuss how a paradigm shift in how we approach cardiovascular health, from focusing on leisure time to also focusing on work time, may help curtail the epidemic of cardiovascular disease in this country.

COVID and Cardiovascular Disease: What We Know in 2021.

PURPOSE OF REVIEW: Coronavirus disease 2019 (COVID-19) has been the cause of significant global morbidity and mortality. Here, we review the literature to date of the short-term and long-term consequences of Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) infection on the heart. RECENT FINDINGS: Early case reports described a spectrum of cardiovascular manifestations of COVID-19, including myocarditis, stress cardiomyopathy, myocardial infarction, and arrhythmia. However, in most cases, myocardial injury in COVID-19 appears to be predominantly mediated by the severity of critical illness rather than direct injury to myocardium from viral particles. While cardiac magnetic resonance imaging remains a powerful tool for diagnosing acute myocarditis, it should be used judiciously in light of low baseline prevalence of myocarditis. Guiding an athletic patient through return to play (RTP) after COVID-19 infection is a challenging process. More recent data show RTP has been a safe endeavor using a screening protocol. "Long COVID" or post-acute sequelae of SARS-CoV-2 infection has also been described. The reported symptoms span a large breadth of cardiopulmonary and neurologic complaints including fatigue, palpitations, chest pain, breathlessness, brain fog, and dysautonomia including postural tachycardia syndrome (POTS). Management of POTS/dysautonomia primarily centers on education, exercise, and salt and fluid repletion. Our understanding of the impact of COVID-19 on the cardiovascular system is constantly evolving. As we enter a new age of survivorship, additional research is needed to catalogue the burden of persistent cardiopulmonary symptoms. Research is also needed to learn how acute management may alter the likelihood and prevalence of this chronic syndrome.

Evolution of Extensively Drug-Resistant Tuberculosis over Four Decades: Whole Genome Sequencing and Dating Analysis of Mycobacterium tuberculosis Isolates from KwaZulu-Natal.

BACKGROUND: The continued advance of antibiotic resistance threatens the treatment and control of many infectious diseases. This is exemplified by the largest global outbreak of extensively drug-resistant (XDR) tuberculosis (TB) identified in Tugela Ferry, KwaZulu-Natal, South Africa, in 2005 that continues today. It is unclear whether the emergence of XDR-TB in KwaZulu-Natal was due to recent inadequacies in TB control in conjunction with HIV or other factors. Understanding the origins of drug resistance in this fatal outbreak of XDR will inform the control and prevention of drug-resistant TB in other settings. In this study, we used whole genome sequencing and dating analysis to determine if XDR-TB had emerged recently or had ancient antecedents. METHODS AND FINDINGS: We performed whole genome sequencing and drug susceptibility testing on 337 clinical isolates of Mycobacterium tuberculosis collected in KwaZulu-Natal from 2008 to 2013, in addition to three historical isolates, collected from patients in the same province and including an isolate from the 2005 Tugela Ferry XDR outbreak, a multidrug-resistant (MDR) isolate from 1994, and a pansusceptible isolate from 1995. We utilized an array of whole genome comparative techniques to assess the relatedness among strains, to establish the order of acquisition of drug resistance mutations, including the timing of acquisitions leading to XDR-TB in the LAM4 spoligotype, and to calculate the number of independent evolutionary emergences of MDR and XDR. Our sequencing and analysis revealed a 50-member clone of XDR M. tuberculosis that was highly related to the Tugela Ferry XDR outbreak strain. We estimated that mutations conferring isoniazid and streptomycin resistance in this clone were acquired 50 y prior to the Tugela Ferry outbreak (katG S315T [isoniazid]; gidB 130 bp deletion [streptomycin]; 1957 [95% highest posterior density (HPD): 1937-1971]), with the subsequent emergence of MDR and XDR occurring 20 y (rpoB L452P [rifampicin]; pncA 1 bp insertion [pyrazinamide]; 1984 [95% HPD: 1974-1992]) and 10 y (rpoB D435G [rifampicin]; rrs 1400 [kanamycin]; gyrA A90V [ofloxacin]; 1995 [95% HPD: 1988-1999]) prior to the outbreak, respectively. We observed frequent de novo evolution of MDR and XDR, with 56 and nine independent evolutionary events, respectively. Isoniazid resistance evolved before rifampicin resistance 46 times, whereas rifampicin resistance evolved prior to isoniazid only twice. We identified additional putative compensatory mutations to rifampicin in this dataset. One major limitation of this study is that the conclusions with respect to ordering and timing of acquisition of mutations may not represent universal patterns of drug resistance emergence in other areas of the globe. CONCLUSIONS: In the first whole genome-based analysis of the emergence of drug resistance among clinical isolates of M. tuberculosis, we show that the ancestral precursor of the LAM4 XDR outbreak strain in Tugela Ferry gained mutations to first-line drugs at the beginning of the antibiotic era. Subsequent accumulation of stepwise resistance mutations, occurring over decades and prior to the explosion of HIV in this region, yielded MDR and XDR, permitting the emergence of compensatory mutations. Our results suggest that drug-resistant strains circulating today reflect not only vulnerabilities of current TB control efforts but also those that date back 50 y. In drug-resistant TB, isoniazid resistance was overwhelmingly the initial resistance mutation to be acquired, which would not be detected by current rapid molecular diagnostics employed in South Africa that assess only rifampicin resistance.
