Abstract [en]

Importance: Adverse pregnancy outcomes are recognized risk enhancers for cardiovascular disease, but the prevalence of subclinical coronary atherosclerosis after these conditions is unknown.

Objective: To assess associations between history of adverse pregnancy outcomes and coronary artery disease assessed by coronary computed tomography angiography screening.

Design, Setting, and Participants: Cross-sectional study of a population-based cohort of women in Sweden (n = 10 528) with 1 or more deliveries in 1973 or later, ascertained via the Swedish National Medical Birth Register, who subsequently participated in the Swedish Cardiopulmonary Bioimage Study at age 50 to 65 (median, 57.3) years in 2013-2018. Delivery data were prospectively collected.

Exposures: Adverse pregnancy outcomes, including preeclampsia, gestational hypertension, preterm delivery, small-for-gestational-age infant, and gestational diabetes. The reference category included women with no history of these exposures.

Main Outcomes and Measures: Coronary computed tomography angiography indexes, including any coronary atherosclerosis, significant stenosis, noncalcified plaque, segment involvement score of 4 or greater, and coronary artery calcium score greater than 100. Results: A median 29.6 (IQR, 25.0-34.9) years after first registered delivery, 18.9% of women had a history of adverse pregnancy outcomes, with specific pregnancy histories ranging from 1.4% (gestational diabetes) to 9.5% (preterm delivery). The prevalence of any coronary atherosclerosis in women with a history of any adverse pregnancy outcome was 32.1% (95% CI, 30.0%-34.2%), which was significantly higher (prevalence difference, 3.8% [95% CI, 1.6%-6.1%]; prevalence ratio, 1.14 [95% CI, 1.06-1.22]) compared with reference women. History of gestational hypertension and preeclampsia were both significantly associated with higher and similar prevalence of all outcome indexes. For preeclampsia, the highest prevalence difference was observed for any coronary atherosclerosis (prevalence difference, 8.0% [95% CI, 3.7%-12.3%]; prevalence ratio, 1.28 [95% CI, 1.14-1.45]), and the highest prevalence ratio was observed for significant stenosis (prevalence difference, 3.1% [95% CI, 1.1%-5.1%]; prevalence ratio, 2.46 [95% CI, 1.65-3.67]). In adjusted models, odds ratios for preeclampsia ranged from 1.31 (95% CI, 1.07-1.61) for any coronary atherosclerosis to 2.21 (95% CI, 1.42-3.44) for significant stenosis. Similar associations were observed for history of preeclampsia or gestational hypertension among women with low predicted cardiovascular risk.

Conclusions and Relevance: Among Swedish women undergoing coronary computed tomography angiography screening, there was a statistically significant association between history of adverse pregnancy outcomes and image-identified coronary artery disease, including among women estimated to be at low cardiovascular disease risk. Further research is needed to understand the clinical importance of these associations.

Abstract [en]

Background and aims: Elevated body weight in adolescence is associated with early cardiovascular disease, but whether this association is traceable to weight in early adulthood, weight in midlife or to weight gain is not known. The aim of this study is to assess the risk of midlife coronary atherosclerosis being associated with body weight at age 20, body weight in midlife and body weight change.

Methods: We used data from 25,181 participants with no previous myocardial infarction or cardiac procedure in the Swedish CArdioPulmonary bioImage Study (SCAPIS, mean age 57 years, 51% women). Data on coronary atherosclerosis, self-reported body weight at age 20 and measured midlife weight were recorded together with potential confounders and mediators. Coronary atherosclerosis was assessed using coronary computed tomography angiography (CCTA) and expressed as segment involvement score (SIS).

Results: The probability of having coronary atherosclerosis was markedly higher with increasing weight at age 20 and with mid-life weight (p < 0.001 for both sexes). However, weight increase from age 20 until mid-life was only modestly associated with coronary atherosclerosis. The association between weight gain and coronary atherosclerosis was mainly seen in men. However, no significant sex difference could be detected when adjusting for the 10-year delay in disease development in women.

Conclusions: Similar in men and women, weight at age 20 and weight in midlife are strongly related to coronary atherosclerosis while weight increase from age 20 until midlife is only modestly related to coronary atherosclerosis.

Abstract [en]

Background: An association between impaired exercise capacity and risk of mortality has been reported among adults with congenital heart disease (CHD). Over the years, treatment methods have improved and may influence outcome. Hence, we report data from a national cohort reflecting a contemporary population.

Objectives: The purpose of this study was to investigate the association between exercise capacity (workload) and mortality in a large registry-based cohort.

Methods: Data on exercise capacity using cycle ergometer were retrieved from the national registry of CHD. The association between predicted exercise capacity (%ECpred) and mortality was analyzed using Cox regression.

Results: In total, 3,721 adults (>18 years, 44.6% women) with CHD were included. The median age was 27.0 years (IQR: 20.8-41.0 years) and mean %ECpred was 77% ± 20%. Over a mean follow-up of 9.4 ± 6.0 years, there were 214 (5.8%) deaths. The Multivariable Cox regression model showed that moderately and severely impaired exercise capacity (50-<70 %ECpred: HR: 2.1, 95% CI: 1.4-3.2, P < 0.001, and <50 %ECpred: HR: 3.5, 95% CI: 2.1-6.0, P < 0.001) and CHD complexity were associated with higher mortality (moderate complexity: HR: 1.9 95% CI: 1.2-3.0, P = 0.003, great complexity: HR: 2.3 95% CI: 1.3-4.2, P = 0.008) when adjusted for New York Heart Association class, physical activity, cardiovascular medication, sex, impaired systemic ventricular function, and age.

Conclusions: Impaired exercise capacity and CHD complexity are independently associated with all-cause mortality in patients with CHD. Exercise capacity is an easily accessible variable that may be a useful tool for risk assessment in adult patients with CHD, but this needs confirmation in prospective studies.

Abstract [en]

Background: Congenital heart disease (CHD) includes a wide range of malformations, from simple lesions, e.g. ventricular septal defect, that resolve spontaneously, to severe lesions, e.g. univentricular heart, not compatible with life without intervention. Tetralogy of Fallot (ToF) is the most common cyanotic congenital heart disease.

In Sweden, approximately 1% of the children are born with CHD each year of which about 30 have ToF. The prognosis has improved remarkably due to advances in surgical techniques as well as peri- and postoperative care. Nowadays, 97% of babies with CHD born in Sweden can be expected to survive into adulthood. Despite huge improvements in prognosis, the relative mortality is still 7 to 97 times higher in patients with CHD, depending on lesion severity, compared with matched controls. Therefore, it is important to improve long-term follow-up and to identify robust and easily available tools to predict poor outcome and optimize timing of possible reinterventions. Addressing quality of life (QoL) has also become more important when survival increases.

The main focus of this thesis was on QoL and long-term outcome in patients with repaired tetralogy of Fallot (rToF). In studies I, II and III, we analysed health related quality of life (HRQoL), prevalence of cardiac devices (i.e. pacemakers and implantable cardioverter defibrillators), and exercise capacity, respectively, in patients with rToF. In study IV, the aim was to broaden the perspective and include patients with a wide range of CHD, and to investigate whether exercise capacity, measured as workload could be of help in predicting mortality.

Methods: The studies were performed as nationwide register studies. Data from the Swedish registry of congenital heart disease (SWEDCON) were used in studies I-IV. Study II also included data from the Swedish ICD and Pacemaker registry. In studies I-III, only patients with rToF were included, whilst study IV included patient with a broad spectrum of CHD diagnoses.

Results: More than half (57%) of the patients with rToF reported best possible HRQoL. New York Heart Association (NYHA) class I and being physically active were associated with best possible HRQoL. Fourteen percent of patients with rToF had a cardiac device, either a pacemaker or an implantable cardioverter defibrillator (ICD). The prevalence of having a cardiac device was lower compared with reports from previous studies, especially for ICDs. Exercise capacity was 75% of predicted in patients with rToF and there was no decline in percent of predicted exercise capacity with age. Low heart rate reserve and low percent of predicted exercise capacity were associated with higher mortality.

In study IV, including a wide range of lesions, percent of predicted exercise capacity was associated with mortality. Patients with percent of predicted exercise capacity between 50 and 69.9% had 1.7 times, and patients with exercise capacity <50% of predicted had 2.2 times higher risk of being deceased, over a median follow-up time of 9 years. NYHA class III-IV and ongoing cardiovascular medication were also associated with increased risk of death when adjusted for sex, physical activity and impaired left ventricular function.

Conclusions: HRQoL in our patients with rToF was good, despite a fairly high prevalence of cardiac devices. Impaired exercise capacity was associated with an increased mortality. Our results reinforce the need for regular evaluation of exercise capacity in patients with CHD to identify patients at risk of worse outcome. Furthermore, the results in this thesis emphasize the importance of assessing NYHA class and physical activity as part of the follow-up since these parameters are easily attainable and strongly associated with HRQoL and exercise capacity.

Abstract [en]

Background and aims: Previous studies reported divergent results on whether metabolically healthy obesity is associated with increased coronary artery calcium and carotid plaques. We investigated this in a cross-sectional fashion in a large, well-defined, middle-aged population using coronary CT angiography (CCTA) and carotid ultrasound. Methods: In the SCAPIS study (50–65 years, 51% female), CCTA and carotid artery ultrasound were performed in 23,674 individuals without clinical atherosclerotic disease. These subjects were divided into six groups according to BMI (normal weight, overweight, obese) and the presence of metabolic syndrome (MetS) according to the NCEP consensus criteria. Results: The severity of coronary artery stenosis was increased in individuals with obesity without MetS compared to normal-weight individuals without MetS (OR 1.47, 95%CI 1.34–1.62; p < 0.0001), even after adjusting for non-HDL-cholesterol and several lifestyle factors. Such difference was not observed for the presence of carotid artery plaques (OR 0.94, 95%CI 0.87–1.02; p = 0.11). Obese or overweight individuals without any MetS criteria (except the waist criterion) showed significantly more pronounced stenosis in the coronary arteries as compared to the normal-weight individuals, while one criterion was needed to show increased plaque prevalence in the carotid arteries. High blood pressure was the most important single criterion for increased atherosclerosis in this respect. Conclusions: Individuals with obesity without MetS showed increased severity of coronary artery stenosis, but no increased occurrence of carotid artery plaques compared to normal-weight individuals without MetS, further emphasizing that obesity is not a benign condition even in the absence of MetS.

Abstract [en]

Background: On a group level, patients with repaired tetralogy of Fallot have impaired exercise capacity. Since exercise capacity is related to prognosis, and more patients survive into higher age, it is important to know the expected exercise capacity at different ages. Furthermore, factors associated with exercise capacity and the relation between exercise capacity and mortality need further evaluation.

Methods: The national register of congenital heart disease was searched for exercise tests in adults with repaired tetralogy of Fallot. The results from exercise tests were compared with national reference data.

Results: 314 patients were identified (median age 33.2 [IQR 24.8-44.7], 40.8% women). The mean percent of predicted workload was 74.8 (±19.6) % without change across ages. In multivariable analysis, NYHA class I (odds ratio [OR]4.2, 95% confidence interval [CI]1.7-10.0) and higher physical activity level (>3 h/week) (OR 3.6, 95%CI 1.8-7.3) were positively associated with higher exercise capacity, while ongoing cardiovascular therapy (OR 0.4, 95%CI 0.2-0.7) and male sex (OR 0.3, 95%CI 0.2-0.6) were negatively associated with higher exercise capacity. Both exercise capacity (HR 0.96, 95%CI 0.93-0.98) and heart rate reserve (HR 0.96, 95%CI 0.94-0.98) were associated with mortality.

Conclusions: In patients with repaired tetralogy of Fallot the exercise capacity was approximately 75% of expected, regardless of age. Patients with better NYHA class and high physical activity level had a higher exercise capacity. Low exercise capacity and low heart rate reserve were associated with higher mortality. Therefore, evaluating exercise capacity as part of follow up is of importance.

Abstract [en]

Objectives: Implantable cardiac devices are common in patients with tetralogy of Fallot (ToF) (18.3–21.3%) according to previous reports from large centres. We conducted this study to investigate the prevalence and incidence of cardiac devices in a less selected population of patients with ToF and assess factors other than arrhythmia associated with having a device. 

Design: 530 adult (≥18 years) patients with repaired ToF were identified in the national registry of congenital heart disease (SWEDCON) and matched with data from the Swedish pacemaker registry. Patients with implantable cardiac devices were compared with patients without devices. 

Results: Seventy-five patients (14.2%) had a device; 51 (9.6%) had a pacemaker and 24 (4.5%) had an implantable cardioverter defibrillator. The incidence in adult age (≥18 years) was 5.9/1000 patient years. Estimated device free survival was 97.5% at twenty, 87.2% at forty and 63.5% at sixty years of age. Compared with previous studies, the prevalence of devices was lower, especially for ICD. In multivariate logistic regression, cardiovascular medication (odds ratio [OR] 3.5, 95% confidence interval [CI] 1.8–6.8), impaired left ventricular function, (OR 2.6, 95%CI 1.3–5.0) and age (OR 1.02, 95%CI 1.002–1.05) were associated with having a device. 

Conclusion: The prevalence of devices in our population, representing a multicenter register cohort, was lower than previously reported, especially regarding ICD. This can be due to differences in treatment traditions with regard to ICD in this population, but it may also be that previous studies have reported selected patients with more severe disease.

Abstract [en]

Background: Early detection of coronary atherosclerosis using coronary computed tomography angiography (CCTA), in addition to coronary artery calcification (CAC) scoring, may help inform prevention strategies. We used CCTA to determine the prevalence, severity, and characteristics of coronary atherosclerosis and its association with CAC scores in a general population.

Methods: We recruited 30 154 randomly invited individuals age 50 to 64 years to SCAPIS (the Swedish Cardiopulmonary Bioimage Study). The study includes individuals without known coronary heart disease (ie, no previous myocardial infarctions or cardiac procedures) and with high-quality results from CCTA and CAC imaging performed using dedicated dual-source CT scanners. Noncontrast images were scored for CAC. CCTA images were visually read and scored for coronary atherosclerosis per segment (defined as no atherosclerosis, 1% to 49% stenosis, or ≥50% stenosis). External validity of prevalence estimates was evaluated using inverse probability for participation weighting and Swedish register data.

Results: In total, 25 182 individuals without known coronary heart disease were included (50.6% women). Any CCTA-detected atherosclerosis was found in 42.1%; any significant stenosis (≥50%) in 5.2%; left main, proximal left anterior descending artery, or 3-vessel disease in 1.9%; and any noncalcified plaques in 8.3% of this population. Onset of atherosclerosis was delayed on average by 10 years in women. Atherosclerosis was more prevalent in older individuals and predominantly found in the proximal left anterior descending artery. Prevalence of CCTA-detected atherosclerosis increased with increasing CAC scores. Among those with a CAC score >400, all had atherosclerosis and 45.7% had significant stenosis. In those with 0 CAC, 5.5% had atherosclerosis and 0.4% had significant stenosis. In participants with 0 CAC and intermediate 10-year risk of atherosclerotic cardiovascular disease according to the pooled cohort equation, 9.2% had CCTA-verified atherosclerosis. Prevalence estimates had excellent external validity and changed marginally when adjusted to the age-matched Swedish background population.

Conclusions: Using CCTA in a large, random sample of the general population without established disease, we showed that silent coronary atherosclerosis is common in this population. High CAC scores convey a significant probability of substantial stenosis, and 0 CAC does not exclude atherosclerosis, particularly in those at higher baseline risk.

Abstract [en]

OBJECTIVE: Although the causality of the obesity–hypertension association is established, the potential for prevention is not. We hypothesized that weight gain between early adulthood and mid-life is associated with higher mid-life blood pressure.

METHODS: We investigated the hypothesis using a large contemporaneous population-based mid-life cohort of men and women aged 50-64 years. Recalled body weight at age 20 years was self-reported, and mid-life body weight and office blood pressures were measured in accordance with a detailed protocol.

RESULTS: On average, men had gained 14.9 (95% CI 14.6-15.2) kg of weight, and women 14.6 (95% CI 14.4-14.9) kg, between age 20 years and the mid-life examination, corresponding to 0.40 (95% CI 0.39-0.41) kg/year for men and women. Both weight at age 20 years and weight at the mid-life examination were associated with mid-life blood pressures. On average, a 10 kg weight increase between age 20 years and mid-life was associated with 2.2 (95% CI 0.9-3.5) mmHg higher systolic and 1.7 (95% CI 0.9-2.5) mmHg higher diastolic mid-life blood pressure in men, and 3.2 (2.5-4.0) mmHg higher systolic and 2.4 (1.9-2.9) mmHg higher diastolic mid-life blood pressure in women. Mid-life weight was more closely associated than weight at age 20 years with mid-life blood pressure. For a given mid-life weight, blood pressure was higher in persons with higher weight gain from age 20 years.

CONCLUSION: In sum, weight gain between early adulthood and mid-life was associated with higher mid-life blood pressure. The magnitude of the association indicates a potentially great public health impact of strategies to prevent weight gain throughout adulthood.

Abstract [en]

Background: Due to improved care, the numbers of patients with tetralogy of Fallot (ToF) are increasing. However, long-term morbidity and need for reinterventions are concerns and also address issues of quality of life (QoL).

Methods: Patients with ToF and valid EuroQol-5 dimensions questionnaire (EQ-5D) were identified in the national Swedish register on congenital heart disease. EQ-5Dindex was calculated and dichotomised into best possible health-related QoL (EQ-5Dindex=1) or differed from 1.

Results: 288 patients met the criteria and were analysed. Univariate logistic regression showed a positive association between New York Heart Association (NYHA) class I (OR 8.32, 95% CI 3.80 to 18.21), physical activity >3 h/week (OR 3.34, 95% CI 1.67 to 6.66) and a better right ventricular function (OR 2.56, 95% CI 1.09 to 6.02). A negative association between symptoms (OR 0.23, 95% CI 0.13 to 0.42), cardiovascular medication (OR 0.31, 95% CI 0.18 to 0.53), age (OR 0.97, 95% CI 0.96 to 0.99) and EQ-5Dindex was observed. In multivariate logistic regression, NYHA I (OR 7.28, 95% CI 3.29 to 16.12) and physical activity >3 h/week (OR 2.27, 95% CI 1.07 to 4.84) remained associated with best possible health-related QoL. Replacing NYHA with symptoms in the model yielded similar results.

Conclusion: In this registry study, self-reported physical activity, staff-reported NYHA class and absence of symptoms were strongly associated with best possible health-related QoL measured by EQ-5D. Physical activity level is a potential target for intervention to improve QoL in this population but randomised trials are needed to test such a hypothesis.
