Cardiac Function and Microcirculation: Type 2 DIABetes and ECHOcardiographic Changes Over Time

2016-11-08 09:23:22 | BioPortfolio


The purpose of this study is to investigate the influence of micro- and macrovascular changes on the cardiac function in relation to left ventricular function and coronary arteries during one year in patients with type 2 diabetes.


The most frequent heart disease in patients with Type 2 Diabetes Mellitus (T2DM) is the premature development of coronary atherosclerosis, which often leads to overt ischemic heart disease (IHD). T2DM can lead to both cardiac dysfunction due to IHD or to diabetic cardiomyopathy. Diabetic cardiomyopathy is defined as an impairment of left ventricular (LV) function without overt obstructive coronary vessel disease. Diabetic cardiomyopathy has been associated with microvascular dysfunction, which leads to the inability of the heart to circulate blood effectively. The microvascular atherosclerotic changes are well known in patients with diabetes , such as impaired vision, kidney function and sensibility. The macrovascular atherosclerotic changes such as plaques in the coronary arteries are strongly associated with reduced left ventricular function.

However, the relationship between micro- and macrovascular atherosclerotic changes and the impact on cardiac function is less certain.

In this study, participants will be consisting of non-diabetic subjects and patients with diabetes type 1 + 2. All of the participants have no history of myocardial infarction, heart failure and symptoms of cardiac disease.

The study population will undergo following examinations:

1. 12-lead electrocardiogram (ECG)

2. Urine- and blood samples.

3. Measurements of anthropometric data and vital parameters

4. Recording of medical history

5. 2D transthoracic echocardiography

6. Coronary Flow Velocity Reserve (CFVR) with adenosine infusion.

7. Coronary Computed Tomography Angiography (CCTA).

The examinations will be repeated at follow-up (however non-diabetic subjects will only have 1 CCTA performed at baseline).

The total study population will be recruited and matched before statistical analysis.

Medical and Biotech [MESH] Definitions

A condition in which the LEFT VENTRICLE of the heart was functionally impaired. This condition usually leads to HEART FAILURE; MYOCARDIAL INFARCTION; and other cardiovascular complications. Diagnosis is made by measuring the diminished ejection fraction and a depressed level of motility of the left ventricular wall.

A form of CARDIAC MUSCLE disease, characterized by left and/or right ventricular hypertrophy (HYPERTROPHY, LEFT VENTRICULAR; HYPERTROPHY, RIGHT VENTRICULAR), frequent asymmetrical involvement of the HEART SEPTUM, and normal or reduced left ventricular volume. Risk factors include HYPERTENSION; AORTIC STENOSIS; and gene MUTATION; (FAMILIAL HYPERTROPHIC CARDIOMYOPATHY).

Rare congenital cardiomyopathies characterized by the lack of left ventricular myocardium compaction. The noncompaction results in numerous prominent trabeculations and a loose myocardial meshwork (spongy myocardium) in the LEFT VENTRICLE. Heterogeneous clinical features include diminished systolic function sometimes associated with left ventricular dilation, that presents either neonatally or progressively. Often, the RIGHT VENTRICLE is also affected. CONGESTIVE HEART FAILURE; PULMONARY EMBOLISM; and ventricular ARRHYTHMIA are commonly seen.

Absence of the orifice between the RIGHT ATRIUM and RIGHT VENTRICLE, with the presence of an atrial defect through which all the systemic venous return reaches the left heart. As a result, there is left ventricular hypertrophy (HYPERTROPHY, LEFT VENTRICULAR) because the right ventricle is absent or not functional.

Diabetes complications in which VENTRICULAR REMODELING in the absence of CORONARY ATHEROSCLEROSIS and hypertension results in cardiac dysfunctions, typically LEFT VENTRICULAR DYSFUNCTION. The changes also result in myocardial hypertrophy, myocardial necrosis and fibrosis, and collagen deposition due to impaired glucose tolerance.
