Vastmanland Myocardial Infarction Study (VaMIS)

• Prevalence of peripheral artery disease (lower extremity artery disease, carotid artery disease, renal artery disease, or abdominal aortic aneurysm) - cross sectional outcome measure. [ Time Frame: baseline ] [ Designated as safety issue: No ]
  Peripheral artery disease as diagnosed by blood pressure measurements in ankles and arms (ankle-brachial-index) for lower extremity artery disease, or as diagnosed by ultrasonography for carotid artery disease, renal artery disease, or abdominal aortic aneurysm.
  
  
• Prevalence of glucometabolic disorders - cross sectional outcome measure. [ Time Frame: basline ] [ Designated as safety issue: No ]
  Known diabetes (from medical records), newly diagnosed diabetes, and impaired glucose tolerance (as diagnosed from plasma glucose levels and/or an oral glucose tolerance test.
  
  
• Prevalence of type D personality - cross sectional measure. [ Time Frame: baseline ] [ Designated as safety issue: No ]
  Type D personality as measured from the type D Scale-14 (DS14) questionnaire.
  
  
• Cardiovascular events - longitudinal outcome measure. [ Time Frame: 5-10 years ] [ Designated as safety issue: No ]
  Cardiovascular events obtained from the Swedish National Causes of Death register and the Swedish National In-Patient register. The registers are linked to the patients by the unique personal identification number assigned to each swedish resident.
  
  

Atherosclerotic arterial disease is the main cause of premature death worldwide and is anticipated to remain the single leading cause of morbidity and mortality the following two decades. Coronary heart disease (CHD) and peripheral arterial disease (PAD) are important clinical manifestation of atherosclerosis which have common underlying arterial pathology, risk factors, and preventive treatments, but they are not often studied concurrently. In the view of secondary prevention we need to know more about the prevalence of cardiovascular disease and prognosis in patients at documented high risk, i.e. patients with manifested CHD. Previous studies on patients with CHD and concomitant PAD have focused mainly on either lower extremity PAD or carotid artery disease. In this project we expand the concept of PAD in patients with CHD to include lower extremity arterial disease, carotid artery disease, renal artery disease, and abdominal aortic aneurysmal disease.

Diabetes mellitus is a well recognised risk factor for cardiovascular morbidity and mortality. However, even prediabetic conditions carry an increased risk. One possible explanation for this increased risk may be the presence of a greater number of atherosclerotic lesions in patients with glucometabolic disorders than in patients without such disorders. We aim to evaluate the association of PAD with glucometabolic status in patients with manifest CHD.

A growing body of research has demonstrated the role of psychosocial and behavioural risk factors in the pathogenesis and prognosis of cardiovascular disorders. Recently, the type D ("distressed") personality construct has been proposed as a strong risk factor for cardiovascular morbidity and mortality. Type D personality is characterized by high levels of two personality traits: negative affectivity (e.g. worry, irritability, and gloom) and social inhibition (e.g. lack of self-assurance and reticence). The data on type D personality as a risk factor for cardiovascular disease has been limited to few research groups and there is a need to replicate those data in other populations.
