Peripheral Artery Disease in Vastmanland (PADVa)

May 7, 2020 updated by: Uppsala University

Observational Study on Cardiac Morphology and Function in Patients With Peripheral Artery Disease in Vastmanland County, Sweden(PADVa).

The main purposes of this study are:

  • to describe the prevalence and degree of reduced left ventricular function and hypertrophy in patients with peripheral arterial disease in comparison to controls from the general population,
  • to evaluate factors of importance to left ventricular dysfunction and hypertrophy in patients with peripheral arterial disease, and
  • to assess the impact of cardiac function and left ventricular hypertrophy on long-term prognosis in patients with peripheral artery disease.

Study Overview

Detailed Description

Left ventricular dysfunction is often a consequence of coronary heart disease (CHD). CHD is prevalent among patients with peripheral artery disease. However, there is limited data regarding left ventricular morphology and function in those patients. In the cross-sectional part of this study we will describe the prevalence of reduced cardiac function and left ventricular hypertrophy in a cohort of patients with peripheral artery disease. The patient outcomes will be compared to control subjects randomly selected from the general population in a case-control design. Further, clinical and genetic determinants of cardiac dysfunction in the patient cohort will be identified. In the longitudinal part of the study, the impact of cardiac function and morphology on cardiovascular mortality and morbidity will be evaluated in the cohort.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Left ventricular ejection fraction (cross-sectional outcome measure)
Time Frame: baseline
LVEF obtained by echocardiographic biplane disk summation method. In the cross-sectional study, the mean value of LVEF and the prevalence of reduced LVEF (LVEF < 50%) in the patient group will be compared to the control group.
baseline
Cardiovascular events (longitudinal outcome measure)
Time Frame: 5-10 years
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.
5-10 years
Left ventricular mass (cross-sectional outcome measure)
Time Frame: baseline
Left ventricular mass obtained by 2-dimensional echocardiography according to the American Society of Echocardiography.
baseline

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Wall motion score index (WMSI)
Time Frame: baseline
Left ventricular wall motion score according to the American Society of Echocardiopgraphy.
baseline
Echocardiographic left ventricular filling variables
Time Frame: baseline
Echocardiographic variables for evaluation of left ventricular diastolic function (e.g. E/A- and E/e'-ratios).
baseline
