Ischemic Heart Disease Clinical Trial
Official title:
Clinical and Morphological Characteristics of Chronic Inflammation in the Myocardium in Patients With Decompensated Heart Failure With Ischemic Systolic Dysfunction
The purpose of the study is to investigate the clinical and morphological characteristics of chronic subclinical inflammation in the myocardium in patients with decompensated heart failure with ischemic systolic dysfunction.
Important reason for the development of chronic heart failure is a viral disease of the
heart, the three phenotypes associated with: the presence of inflammation without viral
agent, implying an autoimmune disease; presence of inflammation and persistent viruses; and
the presence of persistent virus without signs of inflammation.
There is a group of patients with coronary heart disease, which on the background of optimal
treatment is observed progression of clinical symptoms of coronary heart disease with the
subsequent development of heart failure, leading to ischemic cardiomyopathy. Perhaps the
reason for this is the combination of inflammatory and ischemic cardiomyopathies.
Inflammatory cardiomyopathy, involved in the pathogenesis of DCM, includes idiopathic,
autoimmune and infectious subtypes. Inflammatory disease of the myocardium diagnosed by
established histological, immunological and immunohistochemical criteria.
This study will include 60 patients with decompensated heart failure with ischemic left
ventricular systolic dysfunction (LVEF <40%) were hospitalized not earlier than 6 months
after myocardial revascularization. This group of patients will receive standard treatment,
according to national guidelines RSC and ESC, to stabilize heart failure. All patients will
be held PCI to exclude ischemic heart failure decompensation. Also, all patients will be
performed endomyocardial biopsy as a result of immunohistochemical studies will be made on
the separation of the virus and the virus-negative-positive group. After that, the group
will be divided into subgroups: virus - and inflammation in the myocardium inflammation
without viral antigen, viral inflammation of the presence of antigen and the group with the
presence of viral antigen without any signs of inflammation in the myocardium.
The study is nonrandomized.
