[Diagnostic and prognostic significance of QRS-T angle]

Area of Science:

• Cardiology
• Electrophysiology
• Medical Diagnostics

Background:

• The QRS-T angle quantifies ventricular depolarization and repolarization consistency.
• Global myocardial electrical heterogeneity is assessed using the QRS-T angle.
• Recent research highlights the prognostic significance of the QRS-T angle for mortality.

Purpose of the Study:

• To review recent studies on the QRS-T angle's relationship with mortality, coronary heart disease, and heart failure.
• To explore potential mechanisms driving increases in the QRS-T angle.
• To examine the diagnostic and prognostic utility of the QRS-T angle.

Main Methods:

• Systematic literature review of studies published in the last five years.
• Analysis of research investigating the QRS-T angle and cardiovascular outcomes.
• Synthesis of data on mechanisms and clinical applications of the QRS-T angle.

Main Results:

• The QRS-T angle demonstrates prognostic value for overall and cardiovascular mortality.
• Associations between the QRS-T angle and coronary heart disease/heart failure are evident.
• The review discusses potential mechanisms and clinical integration of the QRS-T angle.

Conclusions:

• The QRS-T angle is a valuable indicator of myocardial electrical heterogeneity with significant prognostic implications.
• Further research into its mechanisms and clinical application is warranted.
• The QRS-T angle shows promise for integration into diagnostic and prognostic tools for cardiovascular disease.
