    Area of Science:

    • Cardiology
    • Pathology
    • Biochemistry

    Background:

    • Endomyocardial biopsy is a procedure used in diagnosing heart conditions.
    • Its utility is debated, with some advocating for broad use and others for restricted application.

    Purpose of the Study:

    • To explore the diagnostic and therapeutic potential of endomyocardial biopsy.
    • To evaluate the role of light microscopy, electron microscopy, and biochemical analysis in cardiomyopathies.

    Main Methods:

    • Light microscopy for evaluating tissue fibrosis and cellular hypertrophy.
    • Electron microscopy for detailed subcellular analysis.
    • Biochemical assessment of myocardial tissue.

    Main Results:

    • Light microscopy diagnoses myocarditis, infiltrative cardiomyopathies, and characterizes dilated cardiomyopathies.
    • Electron microscopy provides detailed subcellular information, currently applicable to anthracycline cardiomyopathies.
    • Biochemical analysis shows promise for identifying heart failure abnormalities.

    Conclusions:

    • Endomyocardial biopsy is currently most valuable for myocarditis diagnosis.
    • Microscopic and biochemical analyses offer insights into cardiomyopathy etiology and pathogenesis.
    • Future research, particularly in biochemical assessment, holds significant promise for clinical application in heart failure.
