Endogenous androgens, coronary atheroma and remodeling in women with suspected ischemic heart disease: A report from the Women's Ischemia Syndrome Evaluation (WISE) study.

Background: Women have smaller coronary size than men independent of body surface area. Female to male heart transplantation demonstrates coronary lumen enlargement. Purpose: To investigate relationships between endogenous androgens and coronary luminal size in women with suspected ischemic heart disease (IHD). Methods: We analyzed 69 women with available androgen levels. Results: Group mean age was 54 ± 10 years with 64 % post-menopausal. Lumen cross-sectional area (CSA) and external elastic membrane (EEM) CSA positively correlated with free testosterone (FT) (r = 0.29, p = 0.049; r = 0.29, p = 0.01), respectively, and negatively correlated with SHBG (r = -0.26, p = 0.03; r = -0.29, p = 0.02), respectively. Atheroma CSA positively correlated with FT (r = 0.24. p = 0.05). These correlations became non-significant after adjusting for waist circumference. Conclusions: In women with suspected ischemic heart disease, endogenous androgens, coronary atheroma and luminal size are related, and may be moderated by waist circumference.

Symptom Presentation among Women with Suspected Ischemia and No Obstructive Coronary Artery Disease (INOCA).

Identifying ischemic heart disease (IHD) in women based on symptoms is challenging. Women are more likely to endorse non-cardiac symptoms. More than 50% of women with suspected ischemia have no obstructive coronary disease (and thus, INOCA) and impaired outcomes during follow-up. We aimed to identify symptoms having predictive capacity for INOCA in women with clinical evidence of coronary ischemia. We included 916 women from the original WISE cohort (NCT00000554) who had coronary angiography performed for suspected ischemia and completed a 65-item WISE symptom questionnaire. Sixty-two percent (n = 567) had suspected INOCA. Logistic regression models using a best subsets approach were examined to identify the best predictive model for INOCA based on Score χ2 and AICc. A 10-variable, best-fit model accurately predicted INOCA (AUC 0.72, 95% CI 0.68, 0.75). The model indicated that age ≤ 55 years, left side chest pain, chest discomfort, neck pain, and palpitations had independent, positive relationship (OR > 1) to INOCA (p < 0.001 to 0.008). An inverse relationship (OR < 1) was observed for impending doom, and pain in the jaw, left or bilateral arm, and right hand, interpreted as INOCA associated with the absence of these symptoms (p ≤ 0.001 to 0.023). Our best-fit model accurately predicted INOCA based on age and symptom presentation ~72% of the time. While the heterogeneity of symptom presentation limits the utility of this unvalidated 10-variable model, it has promise for consideration of symptom inclusion in future INOCA prediction risk modeling for women with evidence of symptomatic ischemia.

Longitudinal cardiac remodeling in collegiate American football players as assessed by echocardiography during their collegiate career.

BACKGROUND: Studies on the longitudinal effects of intense physical training on cardiac remodeling are limited, especially in American collegiate football players. HYPOTHESIS: College-level American football training will result in remodeling in a pattern consistent of a sport with moderate static and dynamic demands with increases in both wall and chamber sizes. METHODS: We studied 85 American collegiate football players who underwent transthoracic echocardiogram (TTE) for asymptomatic or mild COVID-19-related illness and compared the changes in echo dimensions to their preparticipation screening TTE. Pre- and posttraining variables were compared using a paired t-test for normally distributed variables. RESULTS: Mean age was 19 years ± 1 and 61% of athletes were Black. Mean follow-up between TTEs was 21 ± 13 months. There was an increase in left atrial volume index (26.4 ± 5.5 to 32.8 ± 8.4 mL/m2 , p < .001), LV end diastolic diameter (5.13 ± 0.4 to 5.27 ± 0.4 cm, p = .003), basal RV diameter (3.28 ± 0.7 to 3.83 ± 0.5 cm, p = <.001), LV mass index (86.7 ± 15.3 to 90.1 ± 15.3, p = .015), and aortic root diameter (3.1 ± 0.4 to 3.2 ± 0.3 cm, p = .03) from pre- to posttraining, with a slightly greater magnitude in athletes with >2 years of training. Presence of left atrial enlargement (≥35 mL/m2 ) increased from 2.9% to 29% pre- to postparticipation in athletes with >2 years training. No significant changes in wall thickness, diastolic function, or right ventricular systolic function were observed. CONCLUSION: American football players college-level training was associated with increases in left and right ventricular chamber sizes, left atrial size, and aortic root diameter.

Effect of Angiotensin II Antagonism on Gastrointestinal Bleeding in Patients With Left Ventricular Assist Devices: A Systematic Review and Meta-Analysis.

The importance of medical therapy to ameliorate the incidence and impact of left ventricular assistance device-related gastrointestinal bleeding has been highlighted recently with several single-center studies. Electronic databases were searched for studies that compared the incidence of gastrointestinal bleeding for those people on left ventricular assist support with and without angiotensin II inhibition. Angiotensin II inhibition was associated with a lower incidence of gastrointestinal bleeding (pooled RR 0.58, 95% confidence interval (CI): 0.34-0.98; p = 0.04], with a trend toward toward lower incidence with arteriovenous malformation-associated gastrointestinal bleeding (pooled RR 0.50, 95% CI: 0.25-1.03; p = 0.06).

Blood pressure characteristics of collegiate female athletes: A call for more focused attention on young women's health.

Background: There is a paucity of data describing the association between blood pressure (BP) and cardiac remodeling in female collegiate athletes. Methods: This retrospective cohort review describes the BP characteristics and echocardiographic features of female collegiate athletes during preparticipation evaluation. We evaluated data from 329 female athletes at two National Collegiate Athletic Association (NCAA) Division I universities who underwent preparticipation evaluation that included medical history, physical examination, 12-lead electrocardiography, and 2-dimensional transthoracic echocardiography. BP values were divided into categories of normal, elevated, stage 1 and stage 2 hypertension based on 2017 ACC/AHA Guidelines. Left ventricular mass index was calculated and indexed to body surface area and further classified into concentric remodeling, concentric hypertrophy, and eccentric hypertrophy. Results: Normal BP values were noted in 184 (56%) female athletes, 88 (26.7%) had elevated BP and 57 (17.3%) had BP values indicating stage 1 or 2 hypertension. The majority of participants were white (n = 136, 73.9%). There was significantly higher body surface area in female athletes with higher BP values: 1.85 ± 0.18 in the stage 1 and 2 hypertension range, 1.82 ± 0.18 in the elevated BP range versus 1.73 ± 0.16 in the normal BP range (p < 0.001). Conclusions: There was a trend toward higher incidence of concentric and eccentric hypertrophy in athletes with higher than normal BP, however no statistical significance was noted. Elevated BP values were frequent among female collegiate athletes, and there is evidence of cardiac remodeling associated with higher BP values.

Preparticipation Cardiac Evaluation Findings in a Cohort of Collegiate Female Athletes.

Knowledge of cardiovascular adaptations in athletes has predominantly focused on males, with limited data available on females who compromise a substantial percentage of all collegiate athletes. A multicenter retrospective cohort review of preparticipation cardiovascular screening data of 329 National Collegiate Athletic Association Division I female athletes was performed. This included physical exams, electrocardiograms, and echocardiograms. Female athletes in class IB sports had elevated systolic blood pressure (p = 0.01). For electrocardiograms, 7 (2%) had abnormal findings: 100% were white; 6 of 7 (86%) participated in IIC sports. Black athletes had longer PR intervals (p ≤ 0.001), whereas white athletes had longer QTc and QRS durations (p = 0.02 and 0.01, respectively). Athletes in IC and IIC sports had longer QTc intervals (p = 0.01). For echocardiographic parameters, no differences were noted based on race. However, significant differences were noted based on classification of sport: athletes in class IC sports had higher left-atrial volume indexes and E/A ratios. Athletes in class IB and IIC had increased left-ventricular wall thicknesses and aortic root dimensions. In conclusion, among one of the largest cohorts of collegiate female athlete preparticipation cardiac screening data to date, significant differences in various parameters based on classification of sport and race were observed. These categorizations should be considered when interpreting cardiovascular screening in female collegiate athletes to improve screening and guide future research.

Predictors of perioperative bleeding in left ventricular assist device implantation.

Study objective: Early bleeding is a common source of morbidity associated with left ventricular assist device (LVAD) implantation. Our objective was to identify potential predictors of peri-implant bleeding. Methods: We conducted a retrospective cohort study of LVAD implants at our institution between January 2010 and November 2018. A total of 210 patients were included. Data were collected for the duration of implant hospitalization, including perioperative invasive hemodynamics, echocardiography and operative details, antiplatelet and anticoagulant use, bleeding events and blood product use, and thromboembolic events. Peri-operative bleeding was defined as a transfusion requirement of >4 units of packed red blood cells in the intraoperative and first 7 days postoperative period, or a major 7-day post-implant overt bleeding event requiring procedural intervention. Results: Perioperative bleeding occurred in 32% of patients and required surgical re-exploration in 9%. Multivariable logistic regression analysis identified history of previous sternotomy (OR 2.63, 95% CI 1.29 to 5.35, p-value 0.008), preoperative glomerular filtration rate <60 ml/min (OR 2.58, 95% CI 1.34 to 4.94, p-value 0.004), preoperative right atrial pressure >13 mm Hg (OR 2.36, 95% CI 1.19 to 4.67, p-value 0.014) and concomitant tricuspid valve repair (OR 2.48, 95% CI 1.23 to 5.01, p-value 0.011) as independent predictors of perioperative bleeding. In-hospital thromboembolic events occurred in 5% of patients, but there were no significant predictors for them. Conclusions: Elevated right atrial pressure appears to be a reversible risk factor for early bleeding that should be targeted during pre-implant optimization of LVAD candidates.

Systematic review and meta-analysis of valve-in-valve transcatheter aortic valve replacement in patients with failed bioprosthetic aortic valves.

AIMS: The aim of this meta-analysis was to evaluate the evidence regarding the rates of procedural success and the incidence of adverse outcomes following valve-in-valve (VIV) transcatheter aortic valve replacement (TAVR) in patients with failed bioprosthetic aortic valves. METHODS AND RESULTS: A systematic search of major electronic databases was conducted for studies relevant to patients with failed bioprosthetic aortic valves undergoing VIV-TAVR. The primary outcome was procedural success. A total of 5,553 patients from 24 studies were included. The mean Society of Thoracic Surgeons (STS) score was 7.84±5.14. The procedural success rate was high (97%, 95% confidence interval [CI]: 94-98%). At 30 days, all-cause mortality was 5% (95% CI: 3-6%), stroke 2% (95% CI: 1-2%), myocardial infarction 1% (95% CI: 1-2%), permanent pacemaker placement 6% (95% CI: 5-8%), and aortic regurgitation 7% (95% CI: 5-10%). At one year, the incidence of all-cause mortality was 12% (95% CI: 10-14%), stroke 3% (95% CI: 2-4%), myocardial infarction 1% (95% CI: 0-2%), and permanent pacemaker placement 7% (95% CI: 5-11%). At three years, the incidence of all-cause mortality was 29% (95% CI: 25-34%) and stroke 6% (95% CI: 5-9%). CONCLUSIONS: VIV-TAVR appears to be associated with high procedural success rates and low adverse outcomes during the short-term and midterm follow-up period.

Optimal systolic blood pressure and reduced long-term mortality in older hypertensive women with prior coronary events - An analysis from INVEST☆.

BACKGROUND: Hypertension and coronary artery disease (CAD) are a prevalent combination in older women, however limited data are available to guide blood pressure (BP) management. We hypothesized that older women with hypertension and CAD may not derive long-term benefit by achieving systolic BP (SBP) < 130 mmHg. METHODS: We analyzed long-term all-cause mortality data from the International Verapamil SR/Trandolapril Study (INVEST), stratified by risk attributable to clinical severity of CAD (women with prior coronary events of myocardial infarction or revascularization considered high risk, all others at low risk) and by age group (50-64 or ≥65 years). The prognostic impact of achieving mean in-trial SBP <130 (referent group) was compared with 130-139 and ≥ 140 mmHg using Cox proportional hazards, adjusting for demographic and clinical characteristics. RESULTS: SBPs <130, 130-139, and ≥140 were achieved in 2960, 3024, and 3232 women, respectively. Among high-risk women aged ≥65 years, those achieving SBP 130-139 mmHg had lower mortality up to 16.7 years later than those with SBP <130 (hazard ratio [HR] 0.81, 95% CI 0.69-0.96). High-risk women aged 50-64 achieving SBP 130-139 had a similar mortality risk as those with SBP <130 (HR 1.21, 95% CI 0.87-1.68), while those achieving SBP ≥140 mmHg had a higher mortality risk than SBP < 130 (HR 1.92, 95% CI 1.37-2.68). A similar pattern was observed among low-risk women ≥65 and <65 years old. CONCLUSION: Among women ≥65 years old with hypertension and prior coronary events, in-trial SBP between 130 and 139 mmHg was associated with lower mortality over the long term versus SBP <130 mmHg.
