Insights
Reduced kidney function (GFR) is linked to coronary artery disease (CAD) and worse outcomes in patients with reversible perfusion defects on g-SPECT scans. Lower GFR predicts CAD and increases mortality risk.
Area of Science:
- Cardiology
- Nephrology
- Nuclear Cardiology
Background:
- Chronic kidney disease (CKD) is a significant risk factor for coronary artery disease (CAD).
- Evaluating the relationship between estimated glomerular filtration rate (GFR), CAD presence, and patient prognosis is crucial.
Purpose of the Study:
- To investigate the association between estimated GFR and the presence of CAD.
- To assess the prognostic value of GFR in patients with reversible perfusion defects on g-SPECT.
Main Methods:
- Utilized gated single-photon emission computed tomography (g-SPECT) for myocardial ischemia evaluation.
- Coronary angiography defined CAD presence (≥70% diameter stenosis).
- Compared GFR levels and outcomes between patients with and without CAD.
Main Results:
- Patients with CAD exhibited lower GFR.
- Reduced GFR (<60 mL/min/1.73 m²) independently predicted CAD.
- Lower GFR correlated with increased myocardial ischemia extent and higher total and cardiac mortality.
Conclusions:
- GFR serves as an accurate marker for CAD in patients with positive g-SPECT scans.
- Reduced GFR is directly correlated with the extent of myocardial ischemia.
- Diminished GFR negatively impacts survival in this patient cohort.
Background:
Chronic kidney disease is a major risk factor for coronary artery disease (CAD). The aim of the study was to examine the association between estimated glomerular filtration rate (GFR), presence of CAD, and prognosis in patients with reversible perfusion defects at gated single-photon emission computed tomography (g-SPECT).
Methods:
Six hundred fifty-eight subjects who had undergone stress/rest g-SPECT for evaluation of myocardial ischemia were divided into two groups according to the presence of CAD, defined by a 70% diameter stenosis in at least one major vessel or principal side branch at coronary angiography.
Results:
GFR was lower in patients with CAD and after adjusting for several clinical characteristics through multivariate logistic regression analysis, reduced (<60 mL/min/1.73 m(2)) GFR remained a significant predictor of CAD (HR 1.80, 95% CI 1.04 to 3.12, P = .036). In addition, reduced GFR was associated with a greater extent of myocardial ischemia, assessed through the summed difference score, as well as with an increase in both total and cardiac mortality.
Conclusions:
In patients with a positive g-SPECT scan, GFR is an accurate marker of CAD and is directly correlated to the extent of myocardial ischemia. Furthermore, reduced GFR had an adverse impact on survival in this particular population.

Renal Clearance
Renal clearance refers to the volume of plasma cleared of a specific substance, such as creatinine, per unit of time. To measure clearance, urine samples are collected over a 24-hour period during each bladder voiding, followed by a single blood sample at the...

One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...
