Cardiovascular Risk Factors in Type 2 Diabetes

Forskare betraktar rör med blodprov i ett labb.

Epidemiological studies have shown that Type 2 diabetes is a potent independent risk factor for cardiovascular disease. The risk of coronary heart disease in Type 2 diabetes is two- to threefold higher than in the general population.

Professor Carl Johan Östgren is the principal investigator in CARDIPP (Cardiovascular Risk Factors in Patients with Diabetes - a Prospective study in Primary Care).

Baseline investigation

The baseline investigation was launched in 2005 and completed in 2008 with the aim of identifying risk markers for cardiovascular disease to facilitate early and individually adjusted interventions in middle-aged men and women with Type 2 diabetes. The participants were recruited consecutively from 22 different primary health care centres in the counties of Östergötland and Jönköping, Sweden and included 761 patients with type 2 diabetes aged 55-65 years. 

The CARDIPP baseline investigation comprised:

  • Patient questionnaire
  • Blood and urine samples stored at -70° C
  • Anthropometric data
  • Office and ambulatory blood pressure recordings
  • Echocardiography
  • Tonometri (SphygmoCor®) for pulse wave analyses and pulse wave velocity
  • Carotid ultrasonography
  • Digital blood pressure recordings

Re-investigation

Four years after the completion of the baseline examination, a re-investigation of the cohort was performed; all participants from the baseline study were invited to the re-investigation. The same study protocol as that in the baseline investigation was used in the re-investigation to measure blood pressure, echocardiography, carotid ultrasonography and tonometry.
Cardiovascular morbidity and mortality

The status of the cohort in terms of cardiovascular morbidity and mortality is currently ascertained from the index date by linkage to the Swedish national cause-of-death and inpatient registries.
