Ankylosing spondylitis (AS) is a systemic disease, which mainly causes to axial joint chronic inflammation. Spine, thoracic and peripheral joints may have varying degrees of activity limitation, and somatic activity is also likely to decline. Ankylosis of the spine and movement disorder of hip are the mainly causes of AS patients' disability, which not only affect the patients' motor function, and but also affect their social interaction, role affordability, mental state and daily living skills. Exercise therapy is the treatment unarmed or with equipment, for injuries, disease, residual patients, to restore or improve dysfunction. There are a number of studies about exercise therapy for joint function of patients with AS, confirmed that exercise therapy plays a crucial role in the treatment of AS patients, on the basis of the medications control.

Objective:To study the value of coronary flow reserve (CFR) via dynamic single photon emission computed tomography (D-SPECT) in evaluating coronary microcirculation dysfunction (CMD) in patients with heart failure.Methods:A prospective research method was adopted. One hundred and ninety-four patients with heart failure from September 2019 to September 2020 in Zhongshan Hospital, Fudan University were selected. The patients were tested for CFR using D-SPECT, and CFR<2 was defined as CMD. The general data were recorded, including age, gender, body mass index (BMI), blood pressure, heart rate, smoking history, New York Heart Association (NYHA) heart function classification, comorbidities and medication situation. The laboratory test results were recorded, including blood urea nitrogen, blood creatinine, blood uric acid, estimated glomerular filtration rate (eGFR), high-sensitivity C-reactive protein (hs-CRP), cardiac troponin T (cTnT) and N terminal pro B type natriuretic peptide (NT-proBNP). The left atrial diameter (LAD), left ventricular end diastolic diameter (LVEDD), left ventricular end systolic diameter (LVESD), interventricular septal thickness (IVST), pulmonary artery systolic pressure (PASP) and left ventricular ejection fraction (LVEF) were measured by cardiac ultrasound. After discharge, patients were followed up in outpatient or telephone contact, with the primary endpoint event being a composite endpoint consisting of cardiovascular death and heart failure readmission. Multiple linear regression analysis was used to analyze the risk factors of CFR. The Kaplan-Meier survival curve was draw, and the log-rank test was used to evaluate the effect of CFR on prognosis.Results:Among 194 patients, 133 patients had CMD (CMD group), and the incidence of CMD was 68.56%; 61 patients did not have CMD (non-CMD group). There were no statistical differences in gender composition, BMI, smoking history proportion, blood pressure, heart rate, hypertension rate, atrial fibrillation rate, diabetes mellitus rate, renal dysfunction rate, medication situation, LAD, LVEDD, IVST, PASP, blood urea nitrogen, blood creatinine, blood uric acid, eGFR and hs-CRP between two groups ( P>0.05). The age, rate of NYHA heart function classification Ⅲ to Ⅳ grade, rate of myocardial infarction or revascularization history, LVESD, cTnT and NT-proBNP in CMD group were significantly higher than those in non-CMD group: (60.7 ± 14.0) years old vs. (55.9 ± 15.8) years old, 54.89% (73/133) vs. 26.23% (16/61), 22.56% (30/133) vs. 1.64% (1/61), (48.8 ± 13.1) mm vs. (44.6 ± 11.4) mm, 0.023 (0.015, 0.046) μg/L vs. 0.015 (0.010, 0.023) μg/L and 1 591 (751, 3 409) ng/L vs. 1 132 (288, 1 860) ng/L, the LVEF was significantly lower than that in non-CMD group: (40.9 ± 14.2)% vs. (45.5 ± 14.1)%, and there were statistical differences ( P<0.05 or <0.01). Multiple linear regression analysis result showed that the cTnT was an risk factor of CFR ( β = - 0.18, 95% CI - 0.82 to - 0.06, P = 0.025). The median followed up time was 230 (136 to 330) d, 10 patients were lost to follow-up, with 58 patients in CMD group completing follow-up and 126 patients in the non-CMD group. The incidences of primary endpoint event and heart failure readmission in CMD group were significantly higher than those in non-CMD group: 23.02% (29/126) vs. 3.45% (2/58) and 15.87% (20/126) vs. 3.45% (2/58), and there were statistical differences ( P<0.01); there was no statistical difference in incidence of cardiovascular death between two groups ( P>0.05). Kaplan-Meier survival curve analysis result showed that the event free survival rate in CMD group was significantly lower than that in non-CMD group, and there was statistical difference (log-rank χ2 = 11.92, P<0.01). Conclusions:CMD is highly prevalent in patients with heart failure, and it is associated with poor prognosis. Improving CMD for improving coronary microcirculation may be potential targets for the treatment of heart failure.
