[24-hour ECG monitoring of patients with different clinical forms of stenocardia]

Area of Science:

• Cardiology
• Clinical Medicine
• Diagnostic Tools

Background:

• Coronary heart disease encompasses various angina pectoris forms, including classical and variant types.
• Differentiating these clinical presentations is crucial for effective therapeutic strategies.

Purpose of the Study:

• To evaluate the utility of 24-hour ECG monitoring in distinguishing between classical and variant angina pectoris.
• To establish the relationship between angina pectoris subtypes and concurrent heart rhythm disturbances.

Main Methods:

• Analysis of 60 coronary heart disease patients, categorized into classical (53) and variant (7) angina groups.
• Utilized 24-hour ECG monitoring, bicycle exercise testing, and coronary angiography.
• Focused on identifying objective ECG patterns during myocardial ischemia episodes.

Main Results:

• 24-hour ECG monitoring provided objective electrocardiographic patterns during myocardial ischemia.
• This technique successfully differentiated between classical and variant angina pectoris.
• Established a correlation between specific angina forms and associated heart rhythm disturbances.

Conclusions:

• 24-hour ECG monitoring is effective in differentiating clinical forms of angina pectoris.
• The findings support the use of 24-hour ECG monitoring for identifying links between angina and arrhythmias.
• This diagnostic approach provides a basis for differential treatment of angina pectoris patients.
