Brief Summary:
Cardiovascular risk functions fail to identify more than 50% of patients who develop cardiovascular disease. This is especially evident in the intermediate-risk patients in which clinical management becomes difficult. The purpose of this study is to analyze if ankle-brachial index (ABI), measures of arterial stiffness, postprandial glucose, glycosylated hemoglobin, self-measured blood pressure and presence of comorbidity are independently associated to incidence of vascular events and whether they can improve the predictive capacity of current risk equations in the intermediate-risk population.

Condition or disease
Myocardial Infarction Angina Pectoris Stroke Peripheral Arterial Disease

Detailed Description:

Primary prevention of cardiovascular diseases is a priority in public health policy of developed and developing countries. The fundamental strategy consists in identifying people in a high risk situation in which preventive measures are effective and efficient. However, specificity and sensitivity of risk equations are modest, which means that approximately 50% of the patients who are likely to develop a vascular event and would benefit from preventive measures are not considered at high risk. While 30% of the subjects considered at risk don't really benefit from preventive measures. Moreover, decisions which imply thousands of people and can determine drug treatment indications are taken every day in primary care centers. These decisions are based mostly on the result of estimations about the probability to develop a vascular disease in 10 years. Improvement of these predictions in our country will have an immediate, clinical and welfare impact and a short term public health effect.

The purpose of this study is to analyze if ankle-brachial index (ABI), measures of arterial stiffness, postprandial glucose, glycosylated hemoglobin, self-measured blood pressure and presence of comorbidity are independently associated to incidence of vascular events and whether they can improve the predictive capacity of current risk equations in the intermediate-risk population.

Study Type : Observational
Actual Enrollment : 2495 participants
Observational Model: Cohort
Time Perspective: Prospective
Official Title: Improving Intermediate Risk Management. MARK Study
Study Start Date : July 2011
Actual Primary Completion Date : December 2013
Actual Study Completion Date : December 2016

Group/Cohort
Intermediate risk population
Population aged between 35 to 74 years who have an intermediate cardiovascular risk, defined as coronary risk between 5% -15% at 10 years according to the Framingham adapted risk equation or vascular mortality risk between 3-5% at 10 years according to the SCORE equation [27].



Primary Outcome Measures :
  1. Vascular events [ Time Frame: 10 years ]
    There will be a telephone follow-up at 10 years to verify the vital status and the existence of hospital admissions due to vascular health problems: Fatal and non fatal coronary heart disease (myocardial infarction or angina pectoris), stroke and peripheral arterial disease


Biospecimen Retention:   Samples Without DNA
Blood sample: Cholesterol and triglycerides concentration, HDL cholesterol, LDL cholesterol, Glucose concentration, glycated hemoglobin and creatinine Urine sample:urine albumin, to calculate the albumin/creatinine index. Postprandial glucose (mg / dl) will be self-measured by patients at home 2 hours after meals (breakfast, lunch and dinner) for one day using an Accu-chek ® glucometer.
