Burden of Ischemic Stroke in Patients With Congenital Heart Disease: A Nationwide, Case-Control Study.

ABSTRACT: Background Patients with congenital heart disease (CHD) are at increased risk of developing ischemic stroke (IS) compared with controls without CHD. However, the long-term outcomes after IS, including IS recurrence and mortality risk, remain unclear. Methods and Results We identified all patients with CHD in Sweden who were born between 1930 and 2017 using the Swedish National Patient Register and the Cause of Death Register. Ten controls without CHD were randomly selected from the general population and matched for birth year and sex for each patient with CHD. The follow-up of the study population was performed between January 1970 and December 2017. In total, 88 700 patients with CHD (50.6% men) and 890 450 matched controls (51.0%) were included in this study. During a mean follow-up of 25.1±22.0 years, patients with CHD had a 5-fold higher risk of developing an index IS (hazard ratio [HR], 5.01; 95% CI, 4.81-5.22) compared with controls. However, the risk of developing a recurrent IS was lower in patients with CHD compared with controls (HR, 0.66; 95% CI, 0.56-0.78), an observation that persisted after adjustment for cardiovascular risk factors and comorbidities. Patients with CHD were also at a significantly lower risk of all-cause mortality after index IS than controls (HR, 0.53; 95% CI, 0.49-0.58). Conclusions Patients with CHD had a 5-fold higher risk of developing index IS compared with matched controls. However, the risk of recurrent IS stroke and all-cause mortality were 34% and 47% lower, respectively, in patients with CHD compared with controls.

Community-based case-control study of childhood stroke risk associated with congenital heart disease.

Project description:A better understanding of the stroke risk factors in children with congenital heart disease (CHD) could inform stroke prevention strategies. We analyzed pediatric stroke associated with CHD in a large community-based case-control study.From 2.5 million children (aged <20 years) enrolled in a Northern California integrated healthcare plan, we identified children with ischemic and hemorrhagic strokes and randomly selected age- and facility-matched stroke-free controls (3 per case). We determined exposure to CHD (diagnosed before stroke) and used conditional logistic regression to analyze stroke risk factors.CHD was identified in 15 of 412 cases (4%) versus 7 of 1236 controls (0.6%). Cases of childhood stroke (occurring between ages 29 days to 20 years) with CHD had 19-fold (odds ratio, 19; 95% confidence interval 4.2-83) increased stroke risk compared to controls. History of CHD surgery was associated with >30-fold (odds ratio, 31; confidence interval 4-241) increased risk of stroke in children with CHD when compared with controls. After excluding perioperative strokes, the history of CHD surgery still increased the childhood stroke risk (odds ratio, 13; confidence interval 1.5-114). The majority of children with stroke and CHD were outpatients at the time of stroke, and almost half the cases who underwent cardiac surgery had their stroke >5 years after the most recent procedure. An estimated 7% of ischemic and 2% of hemorrhagic childhood strokes in the population were attributable to CHD.CHD is an important childhood stroke risk factor. Children who undergo CHD surgery remain at elevated risk outside the perioperative period and would benefit from optimized long-term stroke prevention strategies.

Cumulative Incidence of Infective Endocarditis in Patients with Congenital Heart Disease: A Nationwide, Case-Control Study Over Nine Decades.

Project description:BackgroundCongenital heart disease (CHD) is a lifelong predisposing condition for infective endocarditis (IE). As a consequence of advances in pediatric care, the number of adults with CHD is now exceeding the number of children. The goal of the present study was to determine the cumulative incidence of IE in patients with CHD and detect temporal changes compared with controls.MethodsNationwide registry-based case-control study of patients with CHD born 1930-2017 matched with 10 random controls. Infective endocarditis episodes were linked using the Swedish 10-digit personal identification number.ResultsIn total, 89 541 patients with CHD and 890 470 matched controls were included. In patients with CHD, 1477 IE episodes were registered and 447 episodes in controls. Patients with CHD had 8.5% cumulative incidence of IE at age 87 years, compared with 0.7% in matched controls. Incidence rate of IE per 100 000 person-years was 65.5 (95% confidence interval [CI] 62.2-68.9) and 1.8 (95% CI: 1.7-2.0) in CHD patients and controls, respectively. By age 18 years, patients with CHD had an IE incidence similar to that of 81-year-old controls. Incidence of IE differed by age but not by birth year. Bacterial etiology was registered from 1997 in half of the IE episodes; among CHD IE cases, 43.3% were caused by streptococci and 29.8% by Staphylococcus aureus.ConclusionsInfective endocarditis remains an important complication in patients with CHD. Incidence correlate with age and the number of IE episodes are expected to increase as the CHD population grow older.

Ischemic Stroke in Children and Young Adults With Congenital Heart Disease.

Project description:BackgroundPatients with congenital heart disease (CHD) may be at increased risk of ischemic stroke due to residual shunts, arrhythmias, and other cardiovascular abnormalities. We studied the relative risk and potential factors for developing ischemic stroke in children and young adults with CHD in Sweden.Methods and resultsAll patients in the Swedish Patient Register with a diagnosis of CHD, born between 1970 and 1993, were identified and compared with 10 controls for each patient, matched for age, sex, and county and randomly selected from the general population. Follow-up data through 2011 were collected for both groups. Of 25 985 children and young adults with CHD (51.5% male, 48.5% female), 140 (0.5%) developed ischemic stroke. The hazard ratio for CHD patients developing ischemic stroke was 10.8 (95% CI, 8.5-13.6) versus controls. All major Marelli groups had significantly increased risk, but because of small CHD-group sizes, only atrial septal defect/patent foramen ovale, double-inlet ventricle, and aortic coarctation displayed significantly increased risk. In multivariate analysis of CHD patients, congestive heart failure carried the highest risk for developing ischemic stroke (hazard ratio 6.9 [95% CI, 4.7-10.3]), followed by hypertension and atrial fibrillation, which were also significantly associated with increased risk of ischemic stroke.ConclusionsThe risk of developing ischemic stroke was almost 11 times higher in young patients with CHD than in the general population, although absolute risk is low. Cardiovascular comorbidities were strongly associated with the development of ischemic stroke in young CHD patients.

Ischemic Stroke in Adults With Congenital Heart Disease: A Population-Based Cohort Study.

Project description:Background Congenital heart disease (CHD) is associated with risk factors for ischemic stroke including cardiac arrhythmias and heart failure. However, few long-term follow-up data exist on ischemic stroke risk and associated mortality in adults with CHD. Methods and Results Using Danish nationwide registries, we identified individuals aged ?18 years diagnosed with CHD, at any age, from 1963 to 2017 and a sex and birth year-matched (1:10) general population comparison cohort. We computed risks, as well as sex and birth year-adjusted hazard ratios (aHRs) for ischemic stroke and 30-day post-stroke mortality in CHD adults compared with the general population. Analyses were stratified according to age <60 years (young) and ?60 years (older). We identified 16 836 adults with CHD. The risk of ischemic stroke at age 60 years was 7.4% in the CHD cohort and 2.9% in the general population cohort. The adjusted hazard ratios for ischemic stroke compared with the general population was 3.8 (95% CI: 3.3-4.3) in young CHD adults and 1.6 (95% CI: 1.4-1.9) in older CHD adults. The adjusted hazard ratios for post-stroke mortality compared with the general population was 2.3 (95% CI: 1.2-4.4) in young CHD adults and 1.3 (95% CI: 0.9-1.9) in older CHD adults. Conclusions Both younger and older CHD adults have an increased risk of ischemic stroke and by 60 years of age 7.4% of CHD adults will have had an ischemic stroke. Post-stroke mortality was also increased in CHD adults compared with the general population.

Ischemic Stroke in Young Adults and Preexisting Psychiatric Disorders: A Nationwide Case-Control Study.

Project description:Previous studies showed that psychiatric disorders such as major depression, bipolar disorders, and alcohol misuse are associated with an increased risk of ischemic stroke. However, the link between psychiatric disorders and stroke in the young population is rarely investigated. Using the Taiwan National Health Insurance Research Database, 2063 young adults aged between 18 and 45 years with ischemic stroke and 8252 age- and sex-matched controls were enrolled in our study between 1998 and 2011. Participants who had preexisting psychiatric disorders were identified. After adjusting for preexisting physical disorders and demographic data, patients with ischemic stroke had an increased risk of having preexisting psychiatric disorders, including bipolar disorder (odds ratio [OR]: 2.23, 95% confidence interval [CI]: 1.06?4.67), unipolar depression (OR: 2.15, 95% CI: 1.62?2.86), anxiety disorders (OR: 2.63, 95% CI: 1.87?3.69), and alcohol use disorders (OR: 2.86, 95% CI: 1.79?4.57). Young ischemic stroke (age ?30 years) was related to the risk of preexisting unipolar depression (OR: 1.49, 95% CI: 1.05?2.11), anxiety disorders (OR: 1.99, 95% CI: 1.33?2.97), and alcohol use disorders (OR: 2.54, 95% CI: 1.55?4.14); very young stroke (age <30 years) was only associated with the risk of preexisting unipolar depression (OR: 4.15, 95% CI: 1.47?11.72). Patients who had experienced ischemic stroke at age younger than 45 years had a higher risk of having pre-existing bipolar disorder, unipolar depression, anxiety disorders, and alcohol use disorders than those who did not after adjusting for demographic data and stroke-related medical comorbidities.

Dietary habits in patients with ischemic stroke: a case-control study.

Project description:Background and aimsDiet appears to have some role in stroke development. The objective of our study was to describe the dietary habits in patients admitted with acute ischemic stroke and compare selected dietary components with healthy controls. Adherence to healthy diet behaviors was also assessed.MethodsA case-control study of consecutive patients with acute ischemic stroke admitted to the Neurology Department of Hospital del Mar from 2007 to 2010. Patients were matched by age and sex with control subjects. A previously validated nutritional survey was administered to patients and controls. Demographic data, vascular risk factors, caloric intake and dietary nutrients were evaluated. Intention to follow a healthy diet was also assessed in both groups.ResultsA total of 300 acute ischemic stroke patients and 300 controls with evaluation of dietary habits. No differences were observed in vascular risk factors, except smoking habit, diabetes and ischemic heart disease. Stroke patients reported a higher caloric intake: 2444.8(1736.8-3244.5) vs 2208.7(1753.1-2860.7) Kcal, p = 0.001. After adjusting for energy intake, patients had higher intake of proteins (p<0.001; OR 1.02), total cholesterol (p = 0.001; OR 1.04), and breaded foods (p = 0.001; OR 1.94) and lower consumption of probiotic yogurt (p = 0.002; OR 0.88). Compared to patients, control participants indicated greater intention to eat vegetables (p = 0.002; OR 1.5) and whole foods (p = 0.000; OR 2.4) and reduce their intake of salt (p = 0.002; OR 1.7), fat (p = 0.000; OR 3.7) and sweets (p = 0.004; OR 1.7) than patients.ConclusionWe observed different dietary patterns between stroke patients and controls. Stroke patients have a higher caloric intake and are less concerned about maintaining healthy nutritional habits.

Chronic kidney disease in patients with congenital heart disease: a nationwide, register-based cohort study.

Project description:AimsTo investigate the risk of chronic kidney disease (CKD) in young patients with congenital heart disease (CHD) (age 0-47 years) compared with age- and sex-matched controls without CHD.Methods and resultsUsing data from the Swedish National Patient Register and the Cause of Death Register, 71,936 patients with CHD (50.2% male) born between 1970 and 2017 were identified. Each patient with CHD was matched by sex and age to 10 controls without CHD (n = 714,457). Follow-up data were collected for patients with CHD and controls until 2017. During a median follow-up of 13.5 (5.8; 25.5) years, 379 (0.5%) patients with CHD and 679 (0.1%) controls developed CKD. The risk of CKD was 6.4 times higher in patients with CHD than controls [95% confidence interval (CI): 5.65-7.27] and was highest in patients with severe non-conotruncal defects [hazard ratio (HR): 11.31; 95% CI: 7.37-17.36]. Compared with matched controls, the absolute and relative risks of CKD were greater for CHD patients born between 1997 and 2017 (HR: 9.98; 95% CI: 8.05-13.37) (incidence 39.5 per 100 000 person-years). The risk of CKD remained significantly higher after adjusting for hypertension, acute kidney injury, and diabetes mellitus (HR: 4.37; 95% CI: 3.83-5.00).ConclusionAlthough the absolute risk of CKD in young patients with CHD is relatively low, patients with CHD are six times more likely to develop CKD than non-CHD controls up to the age of 47 years. Further data are needed to inform guidelines on the prevention and follow-up of CKD in CHD patients.

Total small vessel disease burden and functional outcome in patients with ischemic stroke.

Project description:BackgroundCerebral small vessel disease (SVD) is comprised of lacunes, cerebral microbleeds (CMBs), white matter hyperintensities (WMHs), and enlarged perivascular space (EPVS). We investigated the cumulative effect of SVD on 3-month functional outcome following ischemic stroke using the total SVD score.MethodsThe total SVD score of 477 acute ischemic stroke patients with adequate brain MRI was analyzed. We used multivariable ordinal logistic regression analysis to investigate the independent impact of total SVD score on ordinal modified Rankin Scale (mRS) score at 3-month after ischemic stroke.ResultsMean age was 66±14 years, and 61% were men. The distribution of the total SVD score from 0 to 4 was 27%, 24%, 26%, 16%, and 7%, respectively. The proportion of mRS scores 2 or greater was 16% and 47% in total SVD score 0 and 4, respectively. Multivariable ordinal logistic regression analysis results showed that compared with the total SVD score of 0, total SVD scores of 2, 3, and 4 were independently associated with higher mRS scores with adjusted odds ratios (95% confidence intervals) of 1.68 (1.02-2.76), 2.24 (1.25-4.00), and 2.00 (1.02-4.29). Lacunes, CMBs, WMHs but not EPVS were associated with mRS scores at 3 months. However, the impact of each SVD marker on stroke outcome was smaller than that of the total SVD score.ConclusionWe found an independent association between total SVD scores and functional outcome at 3 months following ischemic stroke. The total SVD score may be useful for stratification of patients who are at a high-risk of unfavorable outcomes.

Connection of GLI1 variants to congenital heart disease susceptibility: A case-control study.

Project description:The purpose of this study was to investigate the relationship between glioma-associated oncogene homolog 1 (GLI1) rs2228226 and rs10783826 polymorphisms and congenital heart disease (CHD) risk in a Chinese Han population.Genotyping for our interested polymorphisms was performed using polymerase chain reaction-restriction fragment length polymorphism in 106 CHD patients and 112 healthy controls. Hardy-Weinberg equilibrium status in the control group was also checked via χ test. Differences in genotype and allele frequencies between the case and control groups were analyzed adopting Chi-Squared test as well, and the relative risk of CHD resulting from GLI1 genetic variants was checked via calculating odds ratio (OR) and 95% confidence interval (95%CI).CC genotype of rs2228226 showed significantly higher frequency in CHD patients than in controls (P = .011), indicating that it increased the disease risk (OR = 3.257, 95%CI = 1.280-8.287). Similarly, C allele of the polymorphism elevated CHD incidence by 1.609 folds, compared with G allele (OR = 1.609, 95%CI = 1.089-2.376). However, rs10783826 was not correlated with the occurrence of CHD.GLI1 rs2228226 polymorphism may be a risk factor for CHD in Chinese Han population, but not rs10783826.

Risk of Ischemic Heart Disease and Stroke in Prostate Cancer Survivors: A Nationwide Study in South Korea.

Project description:In this study using national health insurance data, we investigated the risk of ischemic heart disease (IHD) and stroke among prostate cancer (PC) survivors compared with the general population, as well as the risk of cardiovascular disease (CVD) according to primary treatment. A total of 48,298 PC patients diagnosed from 2007 to 2013 were included and matched to non-cancer controls. Compared to the general population, PC survivors had a slightly lower risk of IHD (adjusted hazard ratio [aHR] = 0.89, 95% confidence interval [CI] 0.83-0.96) or stroke (aHR 0.90, 95% CI 0.87-0.95). Especially, survivors who underwent surgery had lower risks of IHD (aHR 0.70, 95% CI 0.61-0.80) or stroke (aHR 0.73, 95% CI 0.67-0.81). Compared to survivors in the active surveillance/watchful waiting group, the androgen deprivation therapy (ADT) group had a significantly greater risk of stroke (aHR 1.16, 95% CI 1.02-1.32), but the IHD risk was not significantly elevated (aHR 1.06, 95% CI 0.88-1.29). In conclusion, PC survivors had a slightly lower risk of CVD compared to the general population, which was attributable to self-selection for PSA screening, specifically in the surgery-only group. CVD risk was dependent on treatment received, and attention should be given to patients who receive ADT.
