Introduction: Therapy with warfarin has been shown to decrease the risk of stroke associated with atrial fibrillation and flutter. Current guidelines recommend warfarin therapy for patients with atrial fibrillation who are at intermediate to high risk of thromboembolism. Multiple studies have shown that increasing age and female gender have been associated with underutilization of warfarin. We evaluated women in the Kentucky Women's Health Registry (KWHR) with self-reported atrial fibrillation to determine the rates of warfarin utilization in this population. Methods: Between November 2009 and June 2010, we administered electronic or mailed surveys to KWHR participants who reported an arrhythmia on the Registry questionnaire. Survey questions targeted arrhythmia identification and treatment, medical and social history, pregnancy history and demographics. Herein we analyze the data to determine baseline characteristics of the atrial fibrillation (and flutter) group, including CHADS 2 score and use of anticoagulation. Results: Of the 572 women initially surveyed, 365 responded to the questionnaire, yielding 107 cases of atrial fibrillation and flutter. Baseline characteristics of this group were notable for high education levels and greater than average annual income (see table). Of this population, 36 of 106, (34%) had a CHADS 2 score of >1. Of the women with CHADS 2 scores of >1 who reported their warfarin use, only 10 of 33 [30% (95% confidence intervals, 17-47%)] were receiving warfarin. As expected, the warfarin treated group tended to be older with mean age 73.4 years vs 61.8 years (p<0.001) with a higher CHADS 2 score (p<0.003). Conclusion: Warfarin anticoagulation is underutilized in this group of Kentucky women. This is not attributable to disparities in socioeconomic status given the relatively affluent, highly educated status of the survey respondents.

Abstract Background Cardiac rehabilitation (CR) is an established model of cardiovascular (CV) prevention that has proven benefits. Availability, characteristics and need of CR programs in Latin-American and Caribbean (LAC) countries remains poorly characterized. This study aims to establish the availability, capacity, density and aspects of CR delivery in LAC. Methods A cross-sectional survey was administered to CR programs in 24 LAC. Local CV organizations and societies identified CR programs. Characteristics of individual CR program were reviewed including: funding sources, core components, healthcare providers, and dose (number of sessions per weeks X total number of weeks) of CR. National CR capacity (median number of patients a program could serve per year X number of programs per country), density (Ischemic Heart Disease [IHD] incidence per year/ national capacity), need (IHD incidence per year- national capacity) and occupancy (median number patients program served per year/national capacity) were computed based on survey responses. Results At least one CR program was identified per LAC country (total 255 programs across 24 countries). Data was collected in 20 of the 24 countries. Responses were received from 139/255 programs (median program response rate=55%; Table 1). Over 50% (n=73) of programs were funded by multiple sources (government, hospital/clinic, private health insurance); Self-payment was reported by 63% programs, in which 24 (33.8%) patients paid over 50% of the cost. Guideline-indicated conditions were accepted in 77% or more programs. Physiotherapists (n=106, 76.3%), cardiologists (n=105, 75.5%) and dietitians (n=79, 56.8%) were the most common healthcare providers on CR teams. Regionally, programs offered 9 (IQR = 8–10) core components (patient education, exercise prescription and initial assessment delivered by nearly all programs). Median CR was 36 (IQR = 24–56) sessions/patient. Twenty-seven (20.9%) programs offered alternative CR models (e.g., home or community-based and hybrid models). Median national capacity was 500 CR spots/country (IQR= 200–2300). Regional density was 1 CR spot per 24 incident IHD patients per year. Greatest need in absolute terms for CR was observed in Brazil, Dominican Republic and Mexico (all with &gt;150,000 spots needed per year to manage incident IHD patients; Table 1). Occupancy ranged from over 100% in Colombia to 15% in Chile (median=60%, IQR = 32%–81%), Table 1. Conclusion In LAC countries, there is very limited capacity to meet the need for CR. Nature of CR services varied regionally. Funding Acknowledgement Type of funding source: None

Background Atrial fibrillation/flutter ( AF ) produces significant morbidity in women and is typically attributed to cardiac remodeling from multiple causes, particularly hypertension. Hypertensive pregnancy disorders ( HPD s) are associated with future hypertension and adverse cardiac remodeling. We evaluated whether women with AF were more likely to have experienced a HPD compared with those without. Methods and Results A nested case–control study was conducted within a cohort of 7566 women who had a live or stillbirth delivery in Olmsted County, Minnesota between 1976 and 1982. AF cases were matched (1:1) to controls based on date of birth, age at first pregnancy, and parity. AF and pregnancy history were confirmed by chart review. We identified 105 AF cases: mean age 57±8 (mean± SD ) years, (controls 56±8 years), 32±8 years (controls 31±8 years) after the first pregnancy. Cases were more likely to have obesity during childbearing years, and hypertension, diabetes mellitus, dyslipidemia, coronary disease, valvular disease, and heart failure at the time of AF diagnosis. Cases were more likely to have a history of HPD s, compared with controls: 28/105 (26.7%) cases versus 12/105 (11.4%) controls, odds ratio: 2.60 (95% confidence interval, 1.21–6.04). After adjustment for hypertension and obesity, the association was attenuated and no longer statistically significant; odds ratio (95% confidence interval, 2.12 (0.92–5.23). Conclusions Women with AF are more likely to have had a HPD , a relationship at least partially mediated by associated obesity and hypertension. Given the high morbidity of AF , studies evaluating the benefit of screening for and management of cardiovascular risk factors in women with a history of HPD should be performed.

Introduction Apical ballooning syndrome (ABS) is typically associated with an antecedent stressful situation. Affected patients have been reported to have higher frequencies of premorbid affective disorders. We hypothesised that patients with ABS would have elevated levels of neuroticism (tendency to experience negative affect) and greater vulnerability to stress. Methods In this cross-sectional study, all active participants in the Mayo Clinic ABS prospective follow-up registry were invited to complete the third edition of the NEO Personality Inventory (NEO-PI-3). The NEO-PI-3 is the universally accepted measure of the ‘Five-Factor Model’ of personality. Inventory responses were scored using the NEO-PI-3 computer program and the data were compared with US normative sample used in standardisation of the inventory. Significance was set at 0.0014 to account for multiple comparisons. Results Of 106 registry participants approached, 53 completed the inventory. There was no difference in age, gender, time from ABS diagnosis, type of antecedent stressor (emotional, physical or none) or severity of initial illness between the responders and non-responders. Responders had mean Neuroticism T-scores of 48.0±10.6 (95% CI 45.1 to 50.9); p=0.18, when compared with the normal mean of 50. There was also no significant difference in the facet scale of Vulnerability: 46.9±8.4 (44.6 to 49.2), p=0.038, at α=0.0014. Conclusions Contrary to our hypothesis, patients with ABS do not manifest higher levels of neuroticism and do not have greater vulnerability to stress than the general population. These findings have implications for the clinicians’ perception of, and approach to, patients with ABS.

Objective Cardiac changes of hypertensive pregnancy include left ventricular hypertrophy (LVH) and diastolic dysfunction. These are thought to regress postpartum. We hypothesised that women with a history of hypertensive pregnancy would have altered LV geometry and function when compared with women with only normotensive pregnancies. Methods In this cohort study, we analysed echocardiograms of 2637 women who participated in the Family Blood Pressure Program. We compared LV mass and function in women with hypertensive pregnancies with those with normotensive pregnancies. Results Women were evaluated at a mean age of 56 years: 427 (16%) had at least one hypertensive pregnancy; 2210 (84%) had normotensive pregnancies. Compared with women with normotensive pregnancies, women with hypertensive pregnancy had a greater risk of LVH (OR: 1.42; 95% CI 1.01 to 1.99, p=0.05), after adjusting for age, race, research network of the Family Blood Pressure Program, education, parity, BMI, hypertension and diabetes. When duration of hypertension was taken into account, this relationship was no longer significant (OR: 1.19; CI 0.08 to 1.78, p=0.38). Women with hypertensive pregnancies also had greater left atrial size and lower mitral E/A ratio after adjusting for demographic variables. The prevalence of systolic dysfunction was similar between the groups. Conclusions A history of hypertensive pregnancy is associated with LVH after adjusting for risk factors; this might be explained by longer duration of hypertension. This finding supports current guidelines recommending surveillance of women following a hypertensive pregnancy, and sets the stage for longitudinal echocardiographic studies to further elucidate progression of LV geometry and function after pregnancy.

The authors aimed to compare renal function by estimated glomerular filtration rate and albuminuria in 3 groups of women: nulliparous women, women with a history of normotensive pregnancies, and women with a history of at least one hypertensive pregnancy. Women who participated in the second F amily B lood P ressure P rogram S tudy visit (2000–2004) and had serum creatinine and urine albumin measurements (n=3015) were categorized as having had no pregnancy lasting >6 months (n=341), having had only normotensive pregnancies (n=2199), or having had at least 1 pregnancy with hypertension (n=475) based on a standardized questionnaire. Women who reported having had at least one pregnancy with hypertension were significantly more likely to be hypertensive (75.6% vs 59.4%, P <.001), diabetic (34.2% vs 27.3%, P ≤.001), and have higher body mass index (32.8 vs 30.5, P <.001) than those who reported normotensive pregnancies. There was a significantly greater risk of microalbuminuria (urine albumin‐creatinine ratio >25 mg/g) in those who reported at least one pregnancy with hypertension ( odds ratio, 1.37; confidence interval, 1.02–1.85; P =.04) than in those with normotensive pregnancies, after adjusting for risk factors for chronic kidney and cardiovascular disease. Hypertension in pregnancy is associated with an increased risk of future microalbuminuria.
