Abstract P117: Mexican Registry of Risk Factors for Cerebrovascular Disease: The “RISK” (RIESGO) Study, a Mexican Approach
Background: The RIESGO (RISK) study was established to investigate associations between lifestyle, risk factors and cerebrovascular diseases in 300 attendees to the annual meeting of the Mexican Academy of Neurology. In these analyses we describe traditional and several new risk factors for Cerebrovascular Disease on the RIESGO participants as well as a novel way to create a cohort.
Methods: The RIESGO study employed a sample of the Mexican Congress of neurology attendees and intends to follow them prospectively. All attendees were invited to participate (n=1300). A survey on lifestyle questions, and clinical evaluations were conducted at the congress site, non-parametric descriptive statistics were used.
Results: 300 attendees (68.8% physicians) participated in RIESGO, 18-83 years old mean 47.1(DE=13.9) and 59% were men. In the RIESGO study, self-reported Diabetes (DM) was 6.8% compared to 20.1% using Glycated Hemoglobin (HbA1c) for diagnosis (>6.5%) and 40% of those with self-reported DM had elevated HbA1c. Also remarkable is the 20.3% major and minor electrocardiographic abnormalities. Systolic and diastolic hypertension was observed in 14.1% and 4.1% respectively, vs 18.4% for self-reported hypertension. Obesity and overweight was observed 66.2% based on BMI > 25kg/m2. Active and former smoking rates were 14.3% and 24.4% respectively, active exercise (>150min/week) was reported in 48.5% and high alcohol consumption (>25 12Oz Beer or equivalent/30days) was 19.9%.
The subclinical outcomes were: intima-media thickness (≥0.8mm) found in 2.3%, carotid plaque in 6% and ventricular hypertrophy (Sokolow) in 1.8%.
We also explored other new risk factors associated with stroke, and found a high heart rate at rest (>70 beats per minute) in 35%, ventricular premature beats 1.1%, prolonged QTc 0.6% and 0% in men and women respectively, finally on the perceived stress scale 97% “never” or “almost never” felt stressed and only 2.3% felt “fairly often stressed”. We will also discuss the association of traditional vs newer risk factors with subclinical outcomes.
Conclusions: These findings indicate a high prevalence and poor awareness and control of major cardiovascular disease risk factors and subclinical outcomes, despite the fact that RIESGO participants have a substantially higher education level and health information than the general Mexican population. These findings reflect the alarming public health problems that diabetes and cardiovascular diseases represent in the Mexican population, even among the most educated individuals. Recurrent attendance at the annual meeting is a novel and convenient way to establish a low cost follow-up study.
