- Lead Sponsor
- Ottawa Heart Institute Research Corporation
- Brief Summary
The full HER CROWN will be a prospective cohort study to propose a novel, women-specific cardiovascular risk score/ algorithm in the prediction of hard cardiovascular outcomes (myocardial infarction, unstable angina, coronary revascularization, stroke, total and cardiovascular mortality). This future study will be the first longitudinal cohort study, to our knowledge, that is focused entirely on researching the pathophysiology and natural history of cardiovascular disease in women with known female-specific risk factors. Further, the investigators are aiming to recruit a sample that is representative of the ethnic distribution in Canada. The proposed pilot study is a feasibility study as an essential preparatory step for HER CROWN.
- Detailed Description
Cardiovascular diseases (CVD), including ischemic heart disease (IHD), peripheral vascular disease (PVD), and stroke, remain the leading preventable cause of death among Canadian women, resulting in over 34,000 deaths per year (age-standardized death rate: 25.1%). Nearly 40% of CVD-related deaths in women are due to IHD. Increased awareness efforts and effective treatments have led to an overall decline in CVD mortality among men and women in high income countries over the past few decades; however, alarmingly, an increase in CVD mortality has been observed in women in the most recent 5 to 10 years in Canada and the United States, and an upward trend in rates of AMI among younger women.
CVD in women remains understudied, under-diagnosed, and undertreated. Clinical guidelines are largely based on studies of men. Several existing large longitudinal cohort studies (e.g., the Nurses' Health Study, The Framingham Heart Study, the PURE study) have included women; however, they have not focused recruitment specifically on high-risk cohorts of women or on risk factors that are unique to women, more common in women, or that disproportionately affect women; they have not used novel measures of subclinical disease in women (e.g., coronary computed tomography angiography and cardiac Rb-positive emission tomography); and most have not recruited representative samples of women in terms of ethnicity or socioeconomic status. CVD risk calculators (e.g., Framingham, the American College of Cardiology ASCVD) focus on traditional risk factors (e.g., tobacco smoking, hypertension, diabetes), do not include sex-specific CVD risk factors or factors that disproportionately affect women, and thus tend to underestimate risk in women. Female-specific factors that have been associated with CVD risk include: premature or late menarche, abnormal menses, premature or early menopause, gestational hypertensive disorders, gestational diabetes, preterm delivery, pregnancy loss, hormonal contraceptive use, and polycystic ovarian syndrome. Risk factors that are under-recognized or disproportionately affect women include: rheumatologic inflammatory disorders (RIDs), depression, anxiety, chronic stress, abuse and intimate partner violence, and health literacy. In addition, a more feminine gender role has been shown to be associated with higher risk of reinfarction after premature acute coronary syndrome, but no additional research on gender roles and future cardiovascular risk is available. Importantly, novel cardiovascular risk markers such as measures of arterial stiffness and aging, among others, have not been prospectively evaluated in a female population. As such, additional longitudinal research is needed to understand the natural history of CVD and the impact of these 'non-conventional' risk factors in women.
A recent article published in the Lancet by a multi-national group of women's heart health experts reviewed existing evidence, identified knowledge gaps, and provided specific recommendations related to CVD research, prevention, treatment, and access to care for women. The HER CROWN longitudinal cohort study will respond to three important gaps identified in this review, specifically: 1) describe the pathophysiology and natural history of cardiovascular disease in women; 2) determine the impact of sex-specific, psychosocial, and socioeconomic risk factors on CVD in women; and, 3) improve CVD risk prediction/ risk stratification models for women. The Vanguard phase of the study will evaluate the feasibility of the full study being planned.
The full HER CROWN will be a prospective matched-cohort study to propose a novel, women-specific cardiovascular risk score/ algorithm in the prediction of hard cardiovascular outcomes (myocardial infarction, unstable angina, coronary revascularization, stroke, total and cardiovascular mortality). This future study will be the first longitudinal cohort study, to our knowledge, that is focused entirely on researching the pathophysiology and natural history of cardiovascular disease in women with known female-specific risk factors. Further, the investigators are aiming to recruit a sample that is representative of the ethnic distribution in Canada. The proposed pilot study is a feasibility study as an essential preparatory step for HER CROWN. The study will be cross-disciplinary, including investigators who specialize in the treatment of cardiovascular disease in women, epidemiology and administrative data, cardiovascular imaging, biomarker research, physical activity, nutrition, nicotine addiction, and mental health who will each inform outcomes and sub-studies.

- Primary Outcome Measures
Name Time Method Demographics questionnaire 18 months Demographics and socioeconomic information
Perceived Stress Scale (PSS) 18 months PSS scores are obtained by reversing responses (e.g., 0 = 4, 1 = 3, 2 = 2, 3 = 1 \& 4 = 0) to the four positively stated items (items 4, 5, 7, \& 8) and then summing across all scale items. A short 4 item scale can be made from questions 2, 4, 5 and 10 of the PSS 10 item scale.
The Index of Spouse Abuse (ISA) 18 months Both the ISA-P and ISA-NP scores range from 0 to 100 where a low score indicates the relative absence of abuse and the higher scores represent the presence of a greater degree or amount of abuse.
Medical History Questionnaire 18 months Past, present medical history, medication, and women's health related information
General Anxiety Disorder-7 (GAD-7) 18 months This is calculated by assigning scores of 0, 1, 2, and 3 to the response categories, respectively, of "not at all," "several days," "more than half the days," and "nearly every day." GAD-7 total score for the seven items ranges from 0 to 21.
0-4: minimal anxiety 5-9: mild anxiety 10-14: moderate anxiety 15-21: severe anxietyPatient Health Questionnaire (PHQ)-9 18 months Several days = 1 More than half the days = 2 Nearly every day = 3
1-4 Minimal depression 5-9 Mild depression 10-14 Moderate depression 15-19 Moderately severe depression 20-27 Severe depressionArterial tonometry 18 months Arterial stiffness and arterial age
International Physical Activity Questionnaire (IPAQ) 18 months Scoring a HIGH level of physical activity on the IPAQ means your physical activity levels equate to approximately one hour of activity per day or more at least a moderate intensity activity level. Scoring a MODERATE level of physical activity on the IPAQ means you are doing some activity more than likely equivalent to half an hour of at least moderate intensity physical activity on most days. Scoring a LOW level of physical activity on the IPAQ means that you are not meeting any of the criteria for either MODERATE of HIGH levels of physical activity.
The Newest Vital Sign (NVS) 18 months Score by giving 1 point for each correct answer (maximum 6 points). Score of 0-1 suggests high likelihood (50% or more) of limited literacy. Score of 2-3 indicates the possibility of limited literacy. Score of 4-6 almost always indicates adequate literacy.
Childhood Trauma Questionnaire (CTQ) 18 months Responses are measured on a 5-point Likert scale (1 = never true, 2 = rarely true, 3 = sometimes true, 4 = often true, 5 = very often true). Each subscale is represented by five questions with a score range from 5 to 25; scores fall into four categories: none to low trauma exposure, low to moderate trauma exposure, moderate to severe trauma exposure and severe to extreme trauma exposure for each scale.
PTSD Checklist-5 (PCL-5) 18 months Respondents are asked to rate how bothered they have been by each of 20 items in the past month on a 5- point Likert scale ranging from 0-4. Items are summed to provide a total severity score (range = 0-80). 0 = Not at all 1 = A little bit 2 = Moderately 3 = Quite a bit 4 = Extremely
Coronary CTA 18 months Coronary artery calcium, plaque presence and plaque characteristics
Cardiac PET 18 months Coronary perfusion and microvascular function
Satisfaction Questionnaire 18 months participant satisfaction and acceptability questionnaire. No score.
SF-12 18 months SF-12v2 items are scored so that a higher score indicates a better health state. For example, functioning items are scored so that a high score indicates better functioning, and the pain item is scored so that a high score indicates freedom from pain. After data entry, items are scored in three steps:
1. item recoding for the four items that require recoding;
2. computing scale scores by summing across items in the same scale (raw scale scores); and,
3. transforming raw scale scores to a 0-100 scale (transformed scale scores).Substance use questionnaire 18 months Nicotine, alcohol, cannabis use measure questionnaire. No score.
Transthoracic echocardiography 18 months Cardiac structure and function
Blood work 18 months CBC, electrolytes, creatinine, fasting lipids, fasting glucose, HbA1c, hs-troponin, NT-proBNP, Lipoprotein (a), LH, FSH, estradiol, progesterone, additional sample for biobanking βhCG test for subsamples participating in PET and Coronary CTA
