[RELATIONSHIP BETWEEN INFLAMMATIONAND HEART DYSSYNCHRONY IN PATIENTS WITH CHRONIC HEART FAILURE AND DIABETES MELLITUS...

Area of Science:

• Cardiology
• Immunology
• Biochemistry

Background:

• Chronic heart failure (CHF) of ischemic origin is a major health concern.
• Co-occurrence of diabetes mellitus type 2 complicates CHF management.
• Cardiac dyssynchrony is a recognized factor in heart failure progression.

Purpose of the Study:

• To investigate the relationship between cardiac dyssynchrony and serum inflammatory markers in patients with CHF and type 2 diabetes.
• To determine the correlation between specific inflammatory markers and parameters of cardiac dyssynchrony.

Main Methods:

• Enzyme immunoassay for serum inflammatory markers (CRP, TNF-α, IL-1β, IL-6).
• Echocardiographic and electrocardiographic methods for detecting cardiac dyssynchrony.
• Statistical analysis to assess correlations between markers and dyssynchrony parameters.

Main Results:

• Patients with cardiac dyssynchrony exhibited significantly elevated levels of CRP, TNF-α, IL-1β, and IL-6.
• Significant direct correlations were found between inflammatory markers (CRP, TNF-α, IL-1β, IL-6) and measures of cardiac dyssynchrony (Ts, Ts-SD, QRS, IVMD).
• Specifically, IL-6 showed a strong correlation with Ts and Ts-SD (r=0.744, p<0.001).

Conclusions:

• Cardiac dyssynchrony is closely associated with heightened systemic inflammation in patients with ischemic CHF and type 2 diabetes.
• Amplification of inflammation appears to contribute to the progression of myocardial dyssynchrony.
• These findings highlight the interplay between inflammation and cardiac mechanics in this patient population.
