<jats:bold>Introduction:</jats:bold>
Heart failure (HF) is a challenging clinical syndrome with complex pathophysiology. Previous studies demonstrated that coronary flow reserve assessed by PET technique was impaired in HF. Transthoracic echocardiography (TTE) can provide reliable data for myocardial blood flow (MBF) which can be measured from coronary sinus (CS). In relation with MBF, coronary vascular resistance (CVR) can be evaluated. In this study, we aimed to evaluate the association of MBF and CVR with clinical data in HF.
</jats:p>
<jats:p>
<jats:bold>Methods:</jats:bold>
The MBF was measured in 100 patients (80 patients with HF (LVEF<30%) and 20 healthy control subjects. MBF was measured from anterograde CS flow TVI at PLAX RV inflow view and CS diameter at A2C view (2Πr2*TVI*heart rate) and indexed to left ventricular mass index. Patient group was categorized based on NYHA functional classes (NYHA FCs).
</jats:p>
<jats:p>
<jats:bold>Results:</jats:bold>
There was an incremental trend for MBF with advancing NYHA FCs (β=0.253, p=0.015). MBF was similar among HF patients due to NYHA FCs. However, MBF was higher in NYHA FC 4 group compared to healthy subjects (p=0.029). Also, CVR was lower in HF patients than the control group (11.15±6.54 vs.24.84±7.29, p<0.001). In the subgroup analysis, CVR was not statistically different between non-ischemic and ischemic etiology of HF (6.91±1.38 vs. 6.31±0.89, p=0.249). Additionally, CVR was significantly lower in NYHA FC 4 compared to other study groups. CVR was positively correlated with peak VO2 (β=0.596, p<0.001), and Seattle Heart Failure Model derived life expectancy (β=0.476, p<0.001) and negatively correlated with serum BNP level (β=-0.450, p=0.001), troponin I (β=-0.366, p=0.001) and serum uric acid level (β=-0.503, p<0.001). In multivariate analysis, CVR is an independent predictor of mortality (HR:0.763 95%CI:0.624-0.933 P=0.008). In ROC analysis, a cut of value 6.73 for CVR has a 74% sensitivity and 66.7 % specifity for prediction of mortality in HF(AUC 0.825 P<0.001).
</jats:p>
<jats:p>
<jats:bold>Conclusion:</jats:bold>
Our results showed that CVR was reduced with advancing FC in HF patients, despite MBF was similar among different FCs. In addition, CVR was significantly correlated with various prognostic markers in HF patients. Therefore, evaluation of MBF hemodynamics, particularly CVR, with TTE may utilize prognostic assessment of HF patients.
