Results

ST-segment depression on resting electrocardiogram without prior cardiac disease and anginal chest pain is independently correlated with 1. age and 2. peak voltage of ST-segment depression in stress electrocardiogram and not independently correlated with left ventricular mass and left ventricular posterior wall thickness in end-diastole on echocardiography; on the contrary, it was not correlated with ischemic signs of stress electrocardiogram analyzed by ST-segment/ heart-rate loop method.

Baseline Characteristics

Patients without prior cardiac disease and anginal chest pain who visited the lead principal investigator's (I, myself) cardiology clinic for diagnosis of the patient's non-anginal chest symptom and/or cardiac examination before non-cardiac surgery

Participant flow

For all the patients: 1. clinical history taking, 2. presence of complicated hypertension, diabetes mellitus and dyslipidemia, 3. cycle ergometer stress electrocardiogram and 4. echocardiographm were examined. Stress electrocardiogram was analyzed by ST-segment/ heart-rate loop method.

Adverse events

None

Outcome measures

Correlation with ST-segment depression on resting electrocardiogram: findings of resting electrocardiogram; Romhilt-Estes score (r = -0.35, p = 0.0014), Sokolow-Lyon's voltage (r = 0.0083, p = 0.93); findings of echocardiogram; left ventricular mass (r = -0.26, p = 0.017), left ventricular posterior wall thickness in end-diastole (r = -0.24, p = 0.029): findings of stress electrocardiogram; peak voltage of ST-segment depression (r = 0.31, p 0.0047), ST/ heart-rate slope (r = -0.0045, p = 0.69), recovery index (r = 0.045, p = 0.69): basic characteristics; age (r = -0.25, p = 0.024)
Receiver operating characteristics (ROC) curves on resting electrocardiographic parameters for estimating left ventricular mass: voltage of ST-segment depression (AUC = 0.62), Sokolow-Lyon's voltage (AUC = 0.53, p = 0.47), Romhilt-Estes score (r = 0.53, p = 0.30), significance test was done comparing AUC of Sokolow-Lyon's voltage and Romhilt-Estes score with that of voltage of ST-segment depression
Multiple logistic regression analysis for voltage of ST-segment depression on resting electrocardiogram: likelihood ratio = 20.91, p < 0.001; age (OR = 1.07, p = 0.015); peak voltage of ST-segment depression on stress electrocardiogram (OR = 0.00, p = 0.004); left ventricular mass (OR = 1.00, P = 0.061), left ventricular posterior wall thickness on end-diastole (OR = 0.94, p = 0.744)

To elucidate the significance of ST-segment depression on resting electrocardiogram in patients without prior cardiac disease and anginal chest pain, by comparing resting and cycle ergometer stress electrocardiogram and echocardiogram. According to this comparison, it is investigated whether the ST-segment depression on resting electrocardiogram is due to 1. silent myocardial ischemia, 2. left ventricular hypertrophy and 3. some other factors. Other parameters: age and gender; complications of hypertension, diabetes mellitus and dyslipidemia were also investigated. The study design was retrospective observational study by searching medical records, electrocardiograms and echocardiograms.
This study was started by the lead principal investigator, (I, myself), when working in Soma General Hospital in 1994 ~ 1997. There was no Research Ethics Committee then in that hospital, and I could enroll only 10 cases, mainly because patients didn't consent to undertake stress test. After an interruption, I enrolled 73 patients in Kojirakawa Shiseido Hospital, in which I served 2006 ~ 2011.
In 2011, data entry was completed.
