Decreased left ventricular compliance can be further investigated with laboratory and ancillary tests such as lipids, blood glucose, cardiac enzymes (e.g., myoglobin, troponin, etc.), electrocardiogram (at rest and under load), 24-hour ambulatory blood pressure monitoring, echocardiography, multislice CT coronary angiography (CTA), chest X-ray, and cardiac magnetic resonance.
During cardiac ultrasound, a decrease in left ventricular compliance may be described, but the diagnosis cannot be made on the basis of this description alone, and it is necessary to combine it with other tests in order to determine the cause of the disease, which may be physiologic (old age, exertion) or pathologic (hypertension, coronary artery disease, hypertrophic cardiomyopathy, etc.), and pathologic causes need to be ruled out first to determine the physiologic causes.
Decreased left ventricular compliance caused by hypertension is mostly due to long-term primary hypertension resulting in high left ventricular load and left ventricular hypertrophy. Lipids, blood glucose, 24-hour ambulatory blood pressure monitoring, echocardiography, carotid ultrasound and other tests can be performed under the guidance of specialized doctors.
In some patients with coronary artery disease, the left ventricular myocardium can be ischemic, and thus the left ventricle diastolic capacity is insufficient, and there is a decrease in ventricular compliance. Tests that may clarify coronary artery disease include cardiac enzymes (e.g., myoglobin, troponin, etc.), electrocardiogram at rest, electrocardiogram loading test, and CTA.
Hypertrophic cardiomyopathy is a hereditary cardiomyopathy that is often associated with hypertrophy of the ventricular muscle and can also cause decreased left ventricular compliance. ECG, echocardiography, cardiac magnetic resonance, etc. can be performed as prescribed by the doctor.
Consult your doctor for any abnormalities in the tests, and perform the relevant tests under the doctor’s guidance to avoid delaying your condition.
