ABSTRACT
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.
ABSTRACT
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.
