This review discusses cardiomyopathies, offering a new etiological classification and highlighting diagnostic approaches. Early diagnosis by general practitioners using routine methods is crucial for improving the generally unfavorable prognosis of these myocardial diseases.
Area of Science:
- Cardiology
- Internal Medicine
Background:
- Cardiomyopathies represent an inhomogeneous group of myocardial diseases with varying etiological factors.
- Existing knowledge on cardiomyopathies reveals discordant opinions among researchers regarding classification and diagnosis.
Purpose of the Study:
- To critically review current knowledge on cardiomyopathies.
- To propose a novel classification based on etiological principles.
- To discuss diagnostic methods and therapeutic strategies.
Main Methods:
- Critical review of existing literature on cardiomyopathies.
- Development of an etiological classification for myocardial diseases.
- Analysis of diagnostic approaches, including routine cardiological examinations.
Main Results:
- The author proposes a new etiological classification for cardiomyopathies.
- Diagnostic signs and symptoms are often nonspecific.
- General practitioners can diagnose cardiomyopathies in two-thirds of patients using routine examinations (history, physical exam, ECG, X-ray).
Conclusions:
- Early diagnosis of cardiomyopathy, achievable through routine examinations, is vital for managing the unfavorable prognosis.
- The proposed etiological classification aids in understanding this complex group of diseases.
- Principles of therapy for cardiomyopathies are presented.
Abstract:
The author offers a critical review of the present knowledge about myocardiopathies and points out discordant opinions of various authors. He presents his own classification of this inhomogeneous group of myocardial diseases, based on the etiological principle. Special attention is given to the present status of diagnostic methods, the author pointing out the nonspecificity of individual signs and symptoms of the disease. It is emphasized that in two thirds of patients even a general practitioner is capable of diagnosing myocardiopathy on the basis of routine cardiological examinations (patient's history, physical examination, ECG and X-ray). This is of great practical importance because the prognosis--although essentially unfavourable--depends to a great extent on an early diagnosis. Finally, principles of therapy at myocardiopathies are presented.
