Abstract Background A healthy lifestyle has been shown to reduce the risk of coronary artery disease (CAD). The extent to which lifestyle influences the risk of CAD for people with pre-existing non-modifiable risk factors is less studied. We therefore examined the associations between a favorable lifestyle and incidence of CAD in population subgroups based on gender, age, educational level, and parental history of myocardial infarction. Methods A total of 26,323 men and women from the Malmö Diet and Cancer study were prospectively followed-up for 18 years. A favorable lifestyle was determined using a four-component lifestyle score based on data collected at baseline: no smoking, no obesity, regular physical activity, and a healthy diet. Cox proportional hazards regression models were used to estimate the relative risk of CAD during follow-up and cumulative risk during a 10-year interval. Results A favorable lifestyle was associated with a 44% (95% confidence interval, 38–48%) lower risk of CAD compared to an unfavorable lifestyle. The relative risk was similarly reduced among subjects subdivided by gender, age group, educational level, and parental history of myocardial infarction. These findings corresponded with a reduced standardized 10-year incidence of CAD of around 40% in each subgroup. Conclusion In this population-based cohort, a favorable lifestyle was associated with a significant reduction of CAD across strata of non-modifiable risk factors. These findings provide support for lifestyle modification as a means for risk reduction in a range of subgroups within a general healthy population.

Abstract. Despite the high prevalence of coronary artery disease (CAD) among patients with end-stage renal disease (ESRD), few studies have identified clinical correlates using national data. The purpose of this study was to determine the prevalence and clinical associations of CAD in a national random sample of new ESRD in the United States in 1996/1997 (n = 4025). Data on demographic characteristics and comorbidities were obtained from the Dialysis Morbidity and Mortality Study, Wave 2. The principal outcome was CAD, defined as the presence of a previous history of CAD, myocardial infarction, or angina, coronary artery bypass surgery, coronary angioplasty, or abnormal coronary angiographic findings. Multivariate logistic regression analysis was used to assess the relationship of conventional factors and proposed uremic factors to the presence of CAD. CAD was present in 38% of patients. Of the total cohort, 17% had a history of myocardial infarction and 23% had angina. Several conventional risk factors, including advancing age, male gender, diabetes mellitus, and smoking, were significantly associated with CAD. Of the proposed uremic factors, lower serum albumin levels but higher residual renal function and higher hematocrit values were significantly associated with the presence of CAD. Vascular comorbid conditions, structural cardiac abnormalities, white race, and geographic location were also strongly correlated with the presence of CAD. This national study suggests that several conventional CAD risk factors may also be risk factors for CAD among the ESRD population. This study identifies nonconventional factors such as serum albumin levels, vascular comorbid conditions, and structural cardiac abnormalities as important disease correlates. Future logitudinal studies are required to explore the relative importance of the relationships observed here.

Q Wave

Unrecognized myocardial infarction (UMI), generally assessed by the presence of a Q-wave on the electrocardiogram, is commonly found. Furthermore, mortality associated with UMI appears to be similar as for recognized myocardial infarction. With delayed enhancement cardiac MRI (DE-CMR) both Q-wave and non-Q wave infarctions can be identified. The aim of this study was to investigate the prevalence and determinants of UMI in high risk subjects without symptomatic coronary artery disease using DE-CMR. A DE-CMR was performed in 502 subjects with clinically manifest non-coronary atherosclerotic disease or marked risk factors for atherosclerosis. As all subjects had no known history of coronary artery disease, subendocardial and transmural scar tissue on DE-CMR was considered an UMI. In all subjects information on atherosclerotic risk factors was collected. Multivariable logistic regression was used to study the relation of risk factors with UMI. DE-CMR was of sufficient image quality in 480 (95.6%) subjects. Interobserver agreement was excellent (weighted kappa = 95%). An UMI was present in 45 (9.4%) of all subjects, and in 38 (13.1%) of 291 men and in 7 (3.7%) of 189 women. The risk of UMI increased from 6.0% (95%CI 2.2 – 9.8%) in those with two risk factors up to 26.2% (95%CI 15.2 – 37.3%) in those with 4 or 5 risk factors (male gender, age above mean of 53 years, ever smoking, history of stroke, and history of aneurysm of the abdominal aorta (AAA)). In multivariable analysis the risk of UMI was related to male gender (OR 2.6 (95%CI 1.1– 6.3)), age (OR 1.0 (95%CI 1.0 –1.1) per year), ever smoking (OR 3.1 (95%CI 1.0 –9.0), history of stroke (OR 2.1 (95%CI 1.0 – 4.4)) and history of AAA (OR 2.3 (95%CI 0.9 –5.9)). In high risk cardiac asymptomatic subjects UMI is common. The risk of UMI increases with increasing presence of risk factors.

Background: The real incidence of Kawasaki disease (KD) in the Maghreb countries (Morocco, Algeria, and Tunisia) is unknown. It is estimated low according to the literature. However, the number of Maghrebi children living in Quebec (Qc) affected by KD seems important. We sought to determine the incidence of KD among Maghrebi children in Qc, Canada, and to study its epidemiological and clinical features and to clarify possible risk factors related or superimposed to their immigration. Methods: A retrospective study of KD in Maghrebi children living in Qc (n=24) (1996-2013), compared to reports from Fes, Morocco (n=23) a doctoral thesis published in 2010 (2001-2009) and from Tunisia (n=31) collected in five university hospitals with four from the Great Tunis and one from Nabeul city (1996-2013). There are no reports available from Algeria. The “country of origin” specific population in the Province of Qc was obtained from Statistics Canada. Results: The annualized incidence rate (AIR) of KD among Maghrebi children in Qc was 9.58/100,000 children under 5 years(Standard-Denominator (SD)).This is 6 times higher in Qc (5.57/SD and 19.02/SD among Tunisian and Moroccan descents) vs Tunisia (Nabeul Governorate) and Morocco (Fes) (0.95/SD and 3.15/SD). Personal and family history of allergy were significantly higher in Qc 42% (10/24) and 75% (18/24), respectively, whereas these features were reported near 0% in both reports from Morocco and Tunisia. The prevalence of incomplete KD criteria was relatively high in the 3 series 46% (11/24) in Qc vs 43% (10/23) and 35% (11/31); (p=NS). Diagnosis was late (gt day 10 of fever) in 1/24(4%) in Qc vs 7/23 (30%) in Morocco and 11/31 (35%) in Tunisia; (p 0.01). IVIG were administered in the acute phase to all patients in Qc, 5/23 in Morocco and 28/31 in Tunisia. However coronary complications were more common in Qc 42% (10/24) vs 22% (5/23) vs 19% (6/31) (p=0.02). Aneurysms were significantly associated with the incomplete form in the 3 groups (p=0.01). Conclusions: The observed AIR of KD in the Maghreb community in Qc is higher than the countries of origin where underdiagnosis is possible. Atopy may still be a risk factor in Qc. The coronary artery disease seems linked not only to therapeutic delay but also to the underlying terrain.
