82652-9 Transient ischemic dilation Left ventricle SPECT

Part Descriptions

LP230008-7 Transient ischemic dilation
Transient ischemic dilation (TID) of the left ventricle (LV) is the phenomenon whereby the LV undergoes transient enlargement of the cavity and thinning of the walls as evidenced by cardiac imaging. TID is associated with severe coronary artery disease and ST depression on EKG. The exact mechanism of TID is not known, but it may be related more to the dilatory effect of diffuse subendocardial ischemia compared to the effect of increased end-diastolic pressure.

82651-1 Washout rate [Ratio] Myocardium SPECT

Part Descriptions

LP229992-5 Washout rate
The washout rate (WR) is a measure of how quickly a tracer is cleared. In cardiac nuclear imaging, the WR is calculated based on tracer uptake in early and delayed images. In one study of patients on multi-drug chemotherapy regimens, the washout rate for patients on chemotherapy was significantly higher compared to controls before any other clinical signs of cardiotoxicity were apparent. PMID: 23173103 Other studies have shown that patients with heart failure of varying etiologies also have a higher WR compared to controls, and an elevated WR may be an indicator for the risk of sudden cardiac death and fatal arrhythmias. However, patients who respond to treatment with beta blockers and/or renin-angiotensin-aldosterone inhibitors, as evidenced by improvement in NYHA functional class, have been found to have a decrease in WR on follow-up imaging studies.

82643-8 Summed rest score for 17 segment model Myocardium SPECT

Part Descriptions

LP229987-5 Summed rest score.17 segment model
The summed rest score (SRS), summed stress score (SSS) and summed difference score (SDS) are variables used to measure cardiac perfusion and ischemia on cardiac SPECT studies. The SRS and SSS are calculated during the rest and stress parts of the study, respectively, and the SDS is the difference between the two.
A five-point scoring system is used to assign a perfusion value to each of the 17 or 20 myocardial segments (depending on which segmentation model is used), each of which corresponds to a coronary artery segment territory, as follows: 0 = normal tracer uptake; 1 = equivocal tracer uptake; 2 = moderate reduction in uptake; 3 = severe reduction of uptake; and 4 = absence of detectable tracer uptake. The values for all of the segments are summed, giving a total possible SRS and SSS of 68 for the 17-segment model and 80 for the 20-segment model. The sum of the differences between the score at rest and score with stress for each segment is the SDS, which represents the amount of ischemia.
The SRS, SSS and SDS can be converted to a percent of the total myocardium involved with stress, ischemic, or fixed defects by dividing the summed scores by either 68 or 80 (the maximum possible score for the 17 and 20-segment model, respectively), and multiplying by 100.

82649-5 Summed rest score Myocardium SPECT

Part Descriptions

LP229994-1 Summed rest score
The summed rest score (SRS), summed stress score (SSS) and summed difference score (SDS) are variables used to measure cardiac perfusion and ischemia on cardiac SPECT studies. The SRS and SSS are calculated during the rest and stress parts of the study, respectively, and the SDS is the difference between the two.
A five-point scoring system is used to assign a perfusion value to each of the 17 or 20 myocardial segments (depending on which segmentation model is used), each of which corresponds to a coronary artery segment territory, as follows: 0 = normal tracer uptake; 1 = equivocal tracer uptake; 2 = moderate reduction in uptake; 3 = severe reduction of uptake; and 4 = absence of detectable tracer uptake. The values for all of the segments are summed, giving a total possible SRS and SSS of 68 for the 17-segment model and 80 for the 20-segment model. The sum of the differences between the score at rest and score with stress for each segment is the SDS, which represents the amount of ischemia.
The SRS, SSS and SDS can be converted to a percent of the total myocardium involved with stress, ischemic, or fixed defects by dividing the summed scores by either 68 or 80 (the maximum possible score for the 17 and 20-segment model, respectively), and multiplying by 100.

Part Descriptions

LP229979-2 Time to end-systole
Left ventricular (LV) systolic dyssynchrony represents variability in the timing of contraction in different LV myocardial segments and is an indicator of LV systolic dysfunction. LV dyssynchrony is evaluated using cardiac gated SPECT and is based on time to end-systole (TES) measurements for each of the 17 LV segments. The TES measures the time from the end of diastole, which is the same for all segments, to the end of systole, which varies across segments depending on the degree of LV dysfunction.
The maximum difference in time to end-systole (MDTES), is the lag between the earliest and the latest end-systole among the 17 LV segments. The standard deviation of time to end-systole (SDTES) is the standard deviation of TES among all of 17 LV segments. Increasing MDTES and SDTES values, which represent increasing LV dyssynchrony, are associated with decreased LV ejection fraction and LV dysfunction. PMID: 22459387
The difference in time to end-systole between the lateral and septal segments (DTES-LS) is also derived from the TES. MDTES, SDTES and DTES-LS are typically expressed as percentages. PMID: 26860109 Source: Regenstrief LOINC, PMID: 22459387

82625-5 Time to peak filling rate Left ventricle SPECT --resting

Part Descriptions

LP229982-6 Time to peak filling rate
Left ventricular (LV) diastolic filling parameters are based on analysis of LV volume over time as measures of LV diastolic function. The peak filling rate (PFR) is the maximum change in LV volume over time (dV/dt) during diastole. The one-third mean filling rate (1/3 MFR) is the average filling rate over the first third of diastole. The time to PFR (TPFR) is the duration of time from the end of systole to the time where the PFR occurs. The ratio of TPFR to R-R interval is the ratio of the time to peak filling to the total time of one cardiac cycle. In one study, patients with the connective tissue disorder systemic sclerosis were found to have significantly higher TPFR and TPFR/R-R interval values compared to controls. PMID: 11216514 Another study of patients with hypertension found that 1/3 MFR measured after stress was significantly lower in patients with hypertension compared to controls, as was the stress PFR.

LP229982-6 Time to peak filling rate
Left ventricular (LV) diastolic filling parameters are based on analysis of LV volume over time as measures of LV diastolic function. The peak filling rate (PFR) is the maximum change in LV volume over time (dV/dt) during diastole. The one-third mean filling rate (1/3 MFR) is the average filling rate over the first third of diastole. The time to PFR (TPFR) is the duration of time from the end of systole to the time where the PFR occurs. The ratio of TPFR to R-R interval is the ratio of the time to peak filling to the total time of one cardiac cycle. In one study, patients with the connective tissue disorder systemic sclerosis were found to have significantly higher TPFR and TPFR/R-R interval values compared to controls. PMID: 11216514 Another study of patients with hypertension found that 1/3 MFR measured after stress was significantly lower in patients with hypertension compared to controls, as was the stress PFR.

82631-3 Maximum difference in time to end-systole Left ventricle SPECT --W stress

Part Descriptions

LP230006-1 Time to end-systole.difference.max
Left ventricular (LV) systolic dyssynchrony represents variability in the timing of contraction in different LV myocardial segments and is an indicator of LV systolic dysfunction. LV dyssynchrony is evaluated using cardiac gated SPECT and is based on time to end-systole (TES) measurements for each of the 17 LV segments. The TES measures the time from the end of diastole, which is the same for all segments, to the end of systole, which varies across segments depending on the degree of LV dysfunction.
The maximum difference in time to end-systole (MDTES), is the lag between the earliest and the latest end-systole among the 17 LV segments. The standard deviation of time to end-systole (SDTES) is the standard deviation of TES among all of 17 LV segments. Increasing MDTES and SDTES values, which represent increasing LV dyssynchrony, are associated with decreased LV ejection fraction and LV dysfunction. PMID: 22459387
The difference in time to end-systole between the lateral and septal segments (DTES-LS) is also derived from the TES. MDTES, SDTES and DTES-LS are typically expressed as percentages. PMID: 26860109 Source: Regenstrief LOINC, PMID: 22459387

Part Descriptions

LP229980-0 Filling rate.diastole.max
Left ventricular (LV) diastolic filling parameters are based on analysis of LV volume over time as measures of LV diastolic function. The peak filling rate (PFR) is the maximum change in LV volume over time (dV/dt) during diastole. The one-third mean filling rate (1/3 MFR) is the average filling rate over the first third of diastole. The time to PFR (TPFR) is the duration of time from the end of systole to the time where the PFR occurs. The ratio of TPFR to R-R interval is the ratio of the time to peak filling to the total time of one cardiac cycle. In one study, patients with the connective tissue disorder systemic sclerosis were found to have significantly higher TPFR and TPFR/R-R interval values compared to controls. PMID: 11216514 Another study of patients with hypertension found that 1/3 MFR measured after stress was significantly lower in patients with hypertension compared to controls, as was the stress PFR.

82638-8 Phase entropy [Score] Left ventricle SPECT --resting

Part Descriptions

LP230000-4 Phase entropy
Phase analysis of the timing of myocardial contraction is used in nuclear cardiology to quantify regional ventricular wall motion and evaluate certain conditions, including bundle branch block, ventricular pacing, and pre-excitation syndromes. Phase and amplitude together are used to classify wall motion, which is also a measure of cardiac dyssynchrony.
The phase value is defined as the amount of shift in the sine or cosine curve (measured in degrees) using the fundamental frequency of the Fourier fitting, and all of the individual phase values are used together to create a phase histogram in order to see the distribution pattern of phase values. Separate histograms are created for the rest and stress portions of the study.

82637-0 Phase bandwidth Left ventricle SPECT --resting

Part Descriptions

LP229999-0 Phase bandwidth
Phase analysis of the timing of myocardial contraction is used in nuclear cardiology to quantify regional ventricular wall motion and evaluate certain conditions, including bundle branch block, ventricular pacing, and pre-excitation syndromes. Phase and amplitude together are used to classify wall motion, which is also a measure of cardiac dyssynchrony.
The phase value is defined as the amount of shift in the sine or cosine curve (measured in degrees) using the fundamental frequency of the Fourier fitting, and all of the individual phase values are used together to create a phase histogram in order to see the distribution pattern of phase values. Separate histograms are created for the rest and stress portions of the study.
Multiple parameters are calculated from the histogram:
1. Phase maximum (degrees);
2. Phase mean (degrees);
3. Phase standard deviation (degrees);
4. Phase bandwidth, which is defined as 95% of the histogram width (degrees); and
5. Phase entropy, which is an index of disorder reported on a scale of 0-1 (0-100%), with 0 meaning complete order and 1 meaning complete disorder.
