Left ventricular function in ischaemic heart disease. A review.

H N Khattri, M J Raphael, B Sharma

    Postgraduate Medical Journal
    |January 1, 1978
    PubMed
    Summary

    Left ventriculography reveals key abnormalities in ischaemic heart disease. Abnormal ventricular responses to exercise indicate ischaemia and can improve with revascularization surgery.

    Area of Science:

    • Cardiology
    • Diagnostic Imaging

    Background:

    • Left ventriculography is crucial for assessing ischaemic heart disease.
    • Coronary arteriography aids in identifying aneurysms associated with blocked arteries.

    Purpose of the Study:

    • To discuss the clinical significance of left ventriculography findings in ischaemic heart disease.
    • To correlate imaging findings with acute and chronic ischaemia.

    Main Methods:

    • Utilizing left ventriculography and coronary arteriography to detect aneurysms.
    • Observing localized abnormal contractions at rest and during stress (exercise or atrial pacing).

    Main Results:

    • Aneurysms are identified by obliterated supplying arteries.
    • Abnormal contractions at rest suggest myocardial infarction.
    • Ischaemia is indicated by abnormal ventricular response to exercise, even without angina.

    Conclusions:

    • Left ventriculography effectively identifies infarcts and acute ischaemia.
    • Exercise-induced ischaemia can be detected non-invasively.
    • Successful revascularization surgery can reverse abnormal ventricular responses.
