Nephrolithiasis in two patients on iron chelation therapy: A case report.

Drug-induced nephrolithiasis can arise from insoluble components within medications or crystallization of metabolites due to changes in metabolism and urinary pH. The connection between drugs utilized for iron chelation therapy (ICT) and nephrolithiasis is not well understood. In this report, we describe two pediatric patients diagnosed with nephrolithiasis while undergoing treatment with the chelating agents deferasirox, deferiprone, and deferoxamine for iron overload secondary to repeat blood transfusion.

Recalibrating Transplant Eligibility Criteria: Ensuring Equitable Access to Organ Transplantation for Intellectually Disabled Persons.

The American with Disabilities Act (ADA) and Section 504 of the Rehabilitation Act have made little progress towards preventing disability-based discrimination within the organ transplant evaluation process. Intellectual and developmental disabilities (I/DD) pose a unique problem for transplant teams and transplant physicians because I/DDs can simultaneously be a legitimate contraindication for transplantation and a mechanism for invidious discrimination against intellectually disabled persons. A culprit for ongoing disability-based discrimination is a transplant center's authority to develop its own eligibility criteria. While medical criteria for eligibility are generally well-settled, psychosocial criteria - an amorphous constellation of risk factors for post-transplant success - can serve as a facially neutral disguise for social worth determinations of individuals with I/DDs. Consequently, individuals with I/DDs are unjustifiably denied eligibility for organ transplantation and transplant-related services.This Article begins by identifying the pitfalls of current federal antidiscrimination legislation. It then discusses the foreseen benefits and drawbacks of House Resolution (H.R.) 8981, a recently proposed federal bill, that expressly prohibits disability-based discrimination within the organ transplant evaluation process. The Article ends by offering potential solutions for professional organizations and transplant centers that aim to provide for equitable access to organ transplantation and transplant-related services for intellectually disabled individuals.

Proteoglycan Remodeling Is Accelerated in Females with Angina Pectoris and Diffuse Myocardial Fibrosis: the iPOWER Study.

Angina and no obstructive coronary artery disease (CAD) have an unfavorable prognosis, possibly due to diffuse myocardial fibrosis (DMF). In DMF the proteoglycans biglycan and versican are actively remodeled by matrix metalloproteinase. We investigated biglycan and versican in females with angina and possible DMF assessed by cardiac magnetic resonance (CMR). Seventy-one females with angina and no obstructive CAD were included. Asymptomatic females served as controls. Versican and biglycan were measured and CMR was performed measuring extracellular volume. Biglycan and versican levels were higher in symptomatic females compared with controls; 31.4 ng/mL vs. 16.4 ng/mL (p < 0.001) and 2.1 ng/mL vs. 1.8 ng/mL (p < 0.001) and moderately correlated to extracellular volume (r2 = 0.38, p<0.001 and r2 = 0.26, p = 0.015). Turnover of biglycan and versican was increased in angina females compared with controls and associated with extracellular volume, supporting a link between angina with no obstructive CAD and fibrotic remodeling.

Myocardial CT perfusion compared with transthoracic Doppler echocardiography in evaluation of the coronary microvascular function: An iPOWER substudy.

BACKGROUND: A significant number of women with angina and no obstructive coronary artery disease (CAD; <50% stenosis) have coronary microvascular dysfunction (CMD) which carries an adverse cardiovascular prognosis. Coronary microvascular function can be evaluated by transthoracic Doppler echocardiography (TTDE) as a coronary flow velocity reserve (CFVR) and by static CT myocardial perfusion (CTP) as a myocardial perfusion reserve (MPR). Whether these methods are correlated is not known. We assessed the correlation between CFVR and MPR and investigated whether women with angina, CMD and no obstructive CAD have reduced MPR compared with asymptomatic women. METHODS: Static CTP with adenosine-induced vasodilation and TTDE of the left anterior descending artery with dipyridamole-induced vasodilation were successfully performed and analysed in 99 women with stable angina and no obstructive CAD and 33 asymptomatic women with no obstructive CAD. CMD was defined as CFVR < 2. RESULTS: Correlation between rate-pressure product corrected MPR and CFVR was weak but significant (r = .23; p = .007). MPR was highest among asymptomatic women with normal CFVR (median [interquartile range; IQR] 158 [145-181] %). Symptomatic women with normal CFVR had reduced MPR (148 [134-162] %; age-adjusted p < .001); however, the lowest MPR was found in symptomatic women with CMD (140 [129-164] %; age-adjusted p < .001), independent of cardiovascular risk factors and haemodynamic parameters (p = .017). CONCLUSION: Women with angina, CMD and no obstructive CAD had markedly diminished MPR compared with asymptomatic women. Correlation between CFVR and MPR was weak, suggesting that CTP and TTDE are not interchangeable for detection of CMD.

Vital exhaustion in women with chest pain and no obstructive coronary artery disease: the iPOWER study.

BACKGROUND: More than half of women with symptoms suggestive of myocardial ischaemia have no obstructive coronary artery disease (CAD), yet they face a higher risk of cardiovascular mortality and morbidity. Both vital exhaustion (VE) and depression have been linked to adverse cardiovascular prognosis in patients with CAD. We aimed to assess whether symptomatic women with no obstructive CAD are more vitally exhausted compared with asymptomatic women. Furthermore, we investigated the overlap between the constructs of VE and depression. METHODS: Prevalence and burden of VE was assessed in symptomatic women with no obstructive CAD (n=1.266) and asymptomatic women (n=2.390). Among symptomatic women, we also assessed chest pain characteristics and symptoms of Hospital Anxiety and Depression Questionnaire. FINDINGS: Median (IQR) VE score was 4 (1-9) and 2 (0-5) in symptomatic and asymptomatic women, respectively (age adjusted, p<0.001). The risk of severe VE was significantly higher in symptomatic women compared with asymptomatic women (OR 3.3, 95% CI 2.5 to 4.4), independent of age and risk factors, and was associated with symptom severity. VE and depression scores were correlated but principal component cluster analysis (PCCA) showed clear distinctiveness between the two constructs. CONCLUSIONS: Women with chest pain and no obstructive CAD are more vitally exhausted compared with asymptomatic women. PCCA showed that VE is distinct from depression in symptomatic women. CLINICAL IMPLICATIONS: Mental health screening focusing on depressive symptomatology in women with chest pain presenting with symptoms of mental and physical exhaustion may overlook VE in these patients.

Testing of Schistosoma mansoni Vaccine Targets.

Vaccination has greatly reduced the burden of human diseases caused by infectious pathogens. Systematic development of vaccine targets requires established protocols to assess immunogenicity and efficacy of such vaccine candidates. Using a leading schistosomiasis vaccine candidate, Sm-p80, as an example, we describe standardized approaches for testing the immunogenicity and efficacy of Schistosoma mansoni vaccine targets. Unlike other parasite systems in which sterile immunity is required, the goal of S. mansoni vaccine targets is overall reduction in morbidity. Methods related to the parasitological parameters described in this chapter allow for the testing of the prophylactic (reduction in adult worm burden), anti-pathology (liver and intestine egg retention), and transmission blocking (fecal egg expulsion and egg hatching rates) efficacies for the vaccine target. The RNA sequencing approaches provide basis for identification of molecular signatures predictive of desirable outcomes for schistosomiasis vaccines.

Decisional Quality Among Patients Making Treatment Decisions for Urolithiasis.

OBJECTIVE: To measure decisional quality, physician loyalty, and treatment preference in patients diagnosed with urolithiasis, a "preference-sensitive" condition, to identify areas of improvement to be addressed by a targeted shared decision-making intervention. METHODS: We identified patients who presented for an initial consultation for urolithiasis from March 2016 to May 2017. Patients completed a 24-item patient experience questionnaire after the consultation which assessed decisional quality domains, physician loyalty, and treatment preference. We summarized treatment preferences before and after the consultation and described the changes. RESULTS: Among the total of 113 patients who met inclusion criteria, 78 (69%) patients chose to participate. Thirty-six (46%) of those patients had evidence of decisional conflict and 42 (54%) did not. Only 1 in 5 patients experiencing decisional conflict reported knowing the benefits and risks of each treatment option. Patients with decisional conflict reported lower perceived shared decision-making, treatment satisfaction, and urolithiasis knowledge. Physician loyalty was lower among patients with decisional conflict as well. Thirty-nine percent of them were 'Promoters' of their urologist, compared to 71% of patients without decisional conflict. Sixty-four percent of patients without decisional conflict identified a treatment preference before consultation, while only 17% of patients who experienced decisional conflict were able to do so. CONCLUSION: Many patients with urolithiasis experience decisional conflict and are unsure of their preferences when making a treatment choice. Uncertainty can correlate with low physician loyalty after consultation. This population may benefit from a shared decision-making intervention that improves decisional quality while incorporating patient-specific preferences.

Evaluation of Implementation Outcomes After Initiation of a Shared Decision-making Program for Men With Prostate Cancer.

OBJECTIVE: To evaluate barriers to implementation of patient decision aids (PDAs) issued in an electronic medical record (EMR). We undertook an implementation outcomes analysis focused on what proportion of men eligible for the PDA received it (penetration), and of the men who received it, how many used it as intended (fidelity). We also evaluated various patient-centered outcomes related to decision-making. MATERIALS AND METHODS: Men with incident localized prostate cancer were recruited from at UCLA from 2013 to 2017. PDA eligibility was determined via weekly EMR review. We also performed a retrospective chart review of all patients seen in clinic for one sample week to identify patients that were missed by the initial eligibility algorithm, and investigated the cause for miscategorization. We analyzed differences in patient-centered outcomes between those who did and did not receive the PDA. RESULTS: About 314/374 men with incident prostate cancer completed the PDA conferring 84% fidelity. PDA penetration under initial identification prospective algorithm was assessed at 100% (n = 2/n = 2). However, penetration assessed by manual retrospective chart review was 20% (n = 2/n = 10). Improvements to the identification algorithm, including new EMR visit types, were identified. PDA completion was associated with less decisional conflict and higher perceived Shared decision-making (all P<.03). CONCLUSION: No previous studies have investigated the challenges of implementing a PDA facilitated by the EMR. We identified modifiable system and EMR-related factors that limited program penetration. Our PDA showed decisional quality benefits.

Overlap between angina without obstructive coronary artery disease and left ventricular diastolic dysfunction with preserved ejection fraction.

BACKGROUND: A link between angina with no obstructive coronary artery disease (CAD) and heart failure with preserved left ventricular ejection fraction has been proposed, but evidence in support of this is lacking. In a cross-sectional study, we investigated whether left ventricular diastolic function in women with angina pectoris and no obstructive CAD differed from a reference population. METHODS: We included 956 women with angina and <50% coronary artery stenosis at invasive coronary angiography. Women with cardiovascular risk factors, but no history of chest pain or cardiac disease served as controls (n = 214). Left ventricular diastolic function was assessed by transthoracic echocardiography. RESULTS: The women with angina were slightly older, had higher body mass index, higher heart rate, and more had diabetes compared with controls while systolic blood pressure was lower. In age-adjusted analyses, angina patients had significantly lower E/A (Estimated difference -0.13, 95% CI: -0.17; -0.08), higher left ventricular mass index (5.73 g/m2, 95% CI: 3.71; 7.75), left atrial volume index (2.34 ml/m2, 95% CI: 1.23; 3.45) and E/e' (0.68, 95% CI: 0.30; 1.05) and a larger proportion had higher estimated left ventricular filling pressure (17% versus 6%, p = 0.001). No between group differences were seen for e' or deceleration time. After adjustment for known cardiovascular risk factors, between group differences for echocardiographic parameters remained statistically significant. CONCLUSIONS: Patients with angina and no obstructive CAD had a more impaired left ventricular diastolic function compared with an asymptomatic reference population. This suggests some common pathophysiological pathway between the two syndromes.

Coronary microvascular dysfunction is associated with cardiac time intervals in women with angina and no obstructive coronary artery disease: An iPOWER substudy.

BACKGROUND: Coronary microvascular dysfunction (CMD) may cause angina in the absence of obstructive coronary artery disease (CAD) and increases the risk of future adverse cardiovascular events. Transthoracic Doppler echocardiography (TTDE) with pharmacological stress can assess coronary flow velocity reserve (CFVR), a measure of coronary microvascular function. However, simpler methods would be preferable for diagnosing CMD. Therefore, we examined the relationship between CFVR and cardiac time intervals measured by TTDE in a cohort of women with angina and no obstructive CAD. METHODS: In a prospective cohort study, we included 389 women with angina, left ventricular ejection fraction > 45%, and no obstructive CAD. CMD was defined as CFVR < 2.0. The study population was divided into three groups according to cutoff values of CFVR < 2, 2 ≤ CFVR ≤ 2.5, and CFVR > 2.5. Isovolumic contraction time (IVCT), ejection time (ET), and isovolumic relaxation time (IVRT) were measured by tissue Doppler M-mode, and the myocardial performance index (MPI = (IVCT + IVRT)/ET) was calculated. RESULTS: Coronary microvascular dysfunction was associated with increasing age, hypertension, higher resting heart rate, and lower diastolic blood pressure. Moreover, CMD was associated with higher E/e' ratio (P = 0.002) and longer IVCT (P < 0.001), higher MPI (P < 0.001) and shorter ET (P = 0.002), but not with IVRT or conventional measures of left ventricular geometry, mass, and function. In multivariable analysis, longer IVCT (P < 0.001) and higher MPI (P = 0.002) remained associated with CMD. CONCLUSION: In women with angina and no obstructive CAD, CMD is associated with longer IVCT and higher MPI indicating a link between CMD and subtle alternations of systolic and combined measures of cardiac time intervals.

Myocardial first pass perfusion assessed by cardiac magnetic resonance and coronary microvascular dysfunction in women with angina and no obstructive coronary artery disease.

Coronary microvascular dysfunction (CMD) is associated with a poor prognosis even in absence of obstructive coronary artery disease. CMD can be assessed as a myocardial blood flow reserve by positron emission tomography (PETMBFR) and as coronary flow velocity reserve by transthoracic Doppler echocardiography (TTDECFVR). Impaired first-pass perfusion assessed by cardiac magnetic resonance (CMR) is an early sign of ischemia. We aimed to investigate the association between CMD and CMR first-pass perfusion. Women (n = 66) with angina pectoris and an invasive coronary angiogram (<50% stenosis) were assessed by TTDECFVR and in a subgroup of these (n = 54) also by PETMBFR. Semi-quantitative evaluation of first-pass perfusion at rest and adenosine stress was assessed by gadolinium CMR in all 66 women. Four measures of CMR perfusion reserve were calculated using contrast upslope, maximal signal intensity and both indexed to arterial input. Mean (standard deviation) age was 62 (8) years. Median (interquartile range) TTDECFVR was 2.3 (1.8;2.7) and PETMBFR was 2.7 (2.2;3.1). Using a cut-off of 2.0 for TTDECFVR and 2.5 for PETMBFR, 25 (38%) and 21 (39%) had CMD, respectively. CMR myocardial perfusion reserve from contrast upslope (CMR_MPRupslope) showed moderate but significant correlation with PETMBFR (R = .46, p < .001) while none of the other CMR variables were associated with CMD. A CMR_MPRupslope cut-off of 0.78 identified CMD, area under the curve 0.73 (p = .001). The results indicate that CMR_MPRupslope may be associated to PETMBFR; a measure of CMD. Further research is needed to validate and implement the use of CMR first pass perfusion in this population.

Ventricular repolarization alterations in women with angina pectoris and suspected coronary microvascular dysfunction.

OBJECTIVES: CMD could be the explanation of angina pectoris with no obstructive CAD and may cause ventricular repolarization changes. We compared T-wave morphology and QTc interval in women with angina pectoris with a control group as well as the associations with CMD. METHODS: Women with angina pectoris and no obstructive coronary artery disease (n=138) and age-matched controls were compared in regard to QTc interval and morphology combination score (MCS) based on T-wave asymmetry, flatness and presence of T-wave notch. CMD was assessed as a coronary flow velocity reserve (CFVR) by transthoracic echocardiography. RESULTS: Women with angina pectoris had significantly longer QTc intervals (429±20ms) and increased MCS (IQR) (0.73 [0.64-0.80]) compared with the controls (419±20ms) and (0.63 [(0.53-0.73]), respectively (both p<0.001). CFVR was associated with longer QTc interval (p=0.02), but the association was attenuated after multivariable adjustment (p=0.08). CONCLUSION: This study suggests that women with angina pectoris have alterations in T-wave morphology as well as longer QTc interval compared with a reference population. CMD might be an explanation.

Coronary microvascular dysfunction and myocardial contractile reserve in women with angina and no obstructive coronary artery disease.

BACKGROUND: Coronary microvascular dysfunction (CMD) is a potential cause of myocardial ischemia and may affect myocardial function at rest and during stress. We investigated whether CMD was associated with left ventricular diastolic and systolic function at rest and during pharmacologically induced hyperemic stress. METHODS: In a prospective cohort study, we included 963 women with angina, left ventricular ejection fraction (LVEF) >45%, and an invasive coronary angiogram without significant stenosis (<50%). Parameters of left ventricular diastolic function, LVEF, speckle tracking-derived global longitudinal strain (GLS), and coronary flow velocity reserve (CFVR) were assessed by transthoracic echocardiography at rest and during dipyridamole stress. The GLS and LVEF reserves were defined as the absolute increases in GLS and LVEF during stress. RESULTS: Coronary flow velocity reserve (CFVR) was measured in 919 women of whom 26% had CMD (defined as CFVR < 2). Coronary microvascular dysfunction (CMD) was associated with higher age and a higher resting heart rate. Women with CMD had a reduced GLS reserve (P = .005), while we found no association between CFVR and LVEF at rest, GLS at rest, or the LVEF reserve, respectively. Global longitudinal strain (GLS) reserve remained associated with CFVR (P = .002) in a multivariable regression analysis adjusted for age, hemodynamic variables, and GLS at rest. In age-adjusted analysis, women with low CFVR had no signs of left ventricular diastolic dysfunction measured by echocardiography at rest. CONCLUSION: The GLS reserve was significantly lower in women with CMD. The mechanisms underlying the association between CMD and GLS reserve warrant further study.

Transthoracic Doppler echocardiography compared with positron emission tomography for assessment of coronary microvascular dysfunction: The iPOWER study.

BACKGROUND: Coronary microvascular function can be assessed by transthoracic Doppler echocardiography as a coronary flow velocity reserve (TTDE CFVR) and by positron emission tomography as a myocardial blood flow reserve (PET MBFR). PET MBFR is regarded the noninvasive reference standard for measuring coronary microvascular function but has limited availability. We compared TTDE CFVR with PET MBFR in women with angina pectoris and no obstructive coronary artery disease and assessed repeatability of TTDE CFVR. METHODS: From a cohort of women with angina and no obstructive coronary artery stenosis at invasive coronary angiography, TTDE CFVR by dipyridamole induced stress and MBFR by rubidium-82 PET with adenosine was successfully measured in 107 subjects. Repeatability of TTDE CFVR was assessed in 10 symptomatic women and in 10 healthy individuals. RESULTS: MBFR was systematically higher than CFVR. Median MBFR (interquartile range, IQR) was 2.68 (2.29-3.10) and CFVR (IQR) was 2.31 (1.89-2.72). Pearson's correlation coefficient was 0.36 (p<0.01). Limits of agreement (2·standard deviation) assessed by the Bland-Altman (confidence interval, CI) method was 1.49 (1.29;1.69) and unaffected by time-interval between examinations. Results were similar when adjusting for rate pressure product or focusing on perfusion of the left anterior descending artery region. Limits of agreement (CI) for repeated CFVR in 10 healthy individuals and in 10 women with angina was 0.44 (0.21;0.68) and 0.48 (0.22; 0.74), respectively. CONCLUSION: CFVR had a good repeatability, but the agreement between CFVR and MBFR was modest. Divergence could be due to methodology differences; TTDE estimates flow velocities whereas PET estimates myocardial blood flow.

Coronary microvascular function and myocardial fibrosis in women with angina pectoris and no obstructive coronary artery disease: the iPOWER study.

BACKGROUND: Even in absence of obstructive coronary artery disease women with angina pectoris have a poor prognosis possibly due to coronary microvascular disease. Coronary microvascular disease can be assessed by transthoracic Doppler echocardiography measuring coronary flow velocity reserve (CFVR) and by positron emission tomography measuring myocardial blood flow reserve (MBFR). Diffuse myocardial fibrosis can be assessed by cardiovascular magnetic resonance (CMR) T1 mapping. We hypothesized that coronary microvascular disease is associated with diffuse myocardial fibrosis. METHODS: Women with angina, a clinically indicated coronary angiogram with <50 % stenosis and no diabetes were included. CFVR was measured using dipyridamole (0.84 mg/kg) and MBFR using adenosine (0.84 mg/kg). Focal fibrosis was assessed by 1.5 T CMR late gadolinium enhancement (0.1 mmol/kg) and diffuse myocardial fibrosis by T1 mapping using a modified Look-Locker pulse sequence measuring T1 and extracellular volume fraction (ECV). RESULTS: CFVR and CMR were performed in 64 women, mean (SD) age 62.5 (8.3) years. MBFR was performed in a subgroup of 54 (84 %) of these women. Mean native T1 was 1023 (86) and ECV (%) was 33.7 (3.5); none had focal fibrosis. Median (IQR) CFVR was 2.3 (1.9; 2.7), 23 (36 %) had CFVR < 2 indicating coronary microvascular disease, and median MBFR was 2.7 (2.2; 3.0) and 19 (35 %) had a MBFR value below 2.5. No significant correlations were found between CFVR and ECV or native T1 (R 2 = 0.02; p = 0.27 and R 2 = 0.004; p = 0.61, respectively). There were also no correlations between MBFR and ECV or native T1 (R 2 = 0.1; p = 0.13 and R 2 = 0.004, p = 0.64, respectively). CFVR and MBFR were correlated to hypertension and heart rate. CONCLUSION: In women with angina and no obstructive coronary artery disease we found no association between measures of coronary microvascular disease and myocardial fibrosis, suggesting that myocardial ischemia induced by coronary microvascular disease does not elicit myocardial fibrosis in this population. The examined parameters seem to provide independent information about myocardial and coronary disease.

"I am not interested in talking with you.".

Mr. M is an eighty-five-year-old who presented to the hospital with congestive heart failure exacerbation, pneumonia, altered mental status, and sepsis. A physician determines that he lacks capacity, and the team in the intensive care unit looks to the patient's daughter, Celia, as his surrogate decision-maker because she is named as an agent in his medical power of attorney form. While in the ICU, Mr. M suffers acute respiratory distress secondary to pneumonia and thus requires intubation. Celia accepts several life-sustaining interventions, but she sporadically refuses other medically indicated therapies. Although providers explain the importance of the ICU insulin regimen for glucose control, she either refuses the insulin or requests a lower dose. The health care team believes that it is providing substandard care and that Celia's medical decisions are not in the patient's best interests, so they request an ethics consultation. When the clinical ethicist attempts to talk with Celia, she refuses to speak with him, saying flatly, "I am not interested in talking with you." The clinical ethicist meets with Celia on a couple of occasions, but she consistently refuses to have a conversation with him. He wonders if the patient's surrogate decision-maker can refuse a clinical ethics consultation and is unsure what his next steps should be.

Coronary Microvascular Function and Cardiovascular Risk Factors in Women With Angina Pectoris and No Obstructive Coronary Artery Disease: The iPOWER Study.

BACKGROUND: The majority of women with angina-like chest pain have no obstructive coronary artery disease when evaluated with coronary angiography. Coronary microvascular dysfunction is a possible explanation and associated with a poor prognosis. This study evaluated the prevalence of coronary microvascular dysfunction and the association with symptoms, cardiovascular risk factors, psychosocial factors, and results from diagnostic stress testing. METHODS AND RESULTS: After screening 3568 women, 963 women with angina-like chest pain and a diagnostic coronary angiogram without significant coronary artery stenosis (<50%) were consecutively included. Mean age (SD) was 62.1 (9.7). Assessment included demographic and clinical data, blood samples, questionnaires, and transthoracic echocardiography during rest and high-dose dipyridamole (0.84 mg/kg) with measurement of coronary flow velocity reserve (CFVR) by Doppler examination of the left anterior descending coronary artery. CFVR was successfully measured in 919 (95%) women. Median (IQR) CFVR was 2.33 (1.98-2.76), and 241 (26%) had markedly impaired CFVR (<2). In multivariable regression analysis, predictors of impaired CFVR were age (P<0.01), hypertension (P=0.02), current smoking (P<0.01), elevated heart rate (P<0.01), and low high-density lipoprotein cholesterol (P=0.02), but these variables explained only a little of the CFVR variation (r(2)=0.09). CFVR was not associated with chest pain characteristics or results from diagnostic stress testing. CONCLUSION: Impaired CFVR was detected in a substantial proportion, which suggests that coronary microvascular dysfunction plays a role in the development of angina pectoris. CFVR was associated with few cardiovascular risk factors, suggesting that CFVR is an independent parameter in the risk evaluation of these women. Symptom characteristics and results from stress testing did not identify individuals with impaired CFVR.
