RESUMO
INTRODUCTION: The Kansas City Cardiomyopathy Questionnaire (KCCQ), Seattle Angina Questionnaire (SAQ), and Minnesota Living with Heart Failure Questionnaire (MLHFQ) are widely used non-preference-based instruments that measure health-related quality of life (QOL) in people with heart disease. However, currently it is not possible to estimate quality-adjusted life-years (QALYs) for economic evaluation using these instruments as the summary scores produced are not preference-based. The MacNew-7D is a heart disease-specific preference-based instrument. This study provides different mapping algorithms for allocating utility scores to KCCQ, MLHFQ, and SAQ from MacNew-7D to calculate QALYs for economic evaluations. METHODS: The study included 493 participants with heart failure or angina who completed the KCCQ, MLHFQ, SAQ, and MacNew-7D questionnaires. Regression techniques, namely, Gamma Generalized Linear Model (GLM), Bayesian GLM, Linear regression with stepwise selection and Random Forest were used to develop direct mapping algorithms. Cross-validation was employed due to the absence of an external validation dataset. The study followed the Mapping onto Preference-based measures reporting Standards checklist. RESULTS: The best models to predict MacNew-7D utility scores were determined using KCCQ, MLHFQ, and SAQ item and domain scores. Random Forest performed well for item scores for all questionnaires and domain score for KCCQ, while Bayesian GLM and Linear Regression were best for MLHFQ and SAQ domain scores. However, models tended to over-predict severe health states. CONCLUSION: The three cardiac-specific non-preference-based QOL instruments can be mapped onto MacNew-7D utilities with good predictive accuracy using both direct response mapping techniques. The reported mapping algorithms may facilitate estimation of health utility for economic evaluations that have used these QOL instruments.

AIMS: We examine the effects of symptoms and cardiovascular disease (CVD) events on health-related quality of life (HRQOL) and healthcare costs in a European population with atrial fibrillation (AF). METHODS AND RESULTS: In the EURObservational Research Programme on AF long-term general registry, AF patients from 250 centres in 27 European countries were enrolled and followed for 2 years. We used fixed effects models to estimate the association of symptoms and CVD events on HRQOL and annual healthcare costs. We found significant decrements in HRQOL in AF patients in whom ST-segment elevation myocardial infarction (STEMI) [-0.075 (95% confidence interval -0.144, -0.006)], angina or non-ST-elevation myocardial infarction (NSTEMI) [-0.037 (-0.071, -0.003)], new-onset/worsening heart failure [-0.064 (-0.088, -0.039)], bleeding events [-0.031 (-0.059, -0.003)], thromboembolic events [-0.071 (-0.115, -0.027)], mild symptoms [0.037 (-0.048, -0.026)], or severe/disabling symptoms [-0.090 (-0.108, -0.072)] occurred during the follow-up. During follow-up, annual healthcare costs were associated with an increase of 11 718 (8497, 14 939) in patients with STEMI, 5823 (4757, 6889) in patients with angina/NSTEMI, 3689 (3219, 4158) in patients with new-onset or worsening heart failure, 3792 (3315, 4270) in patients with bleeding events, and 3182 (2483, 3881) in patients with thromboembolic events, compared with AF patients without these events. Healthcare costs were primarily driven by inpatient costs. There were no significant differences in HRQOL or healthcare resource use between EU regions or by sex. CONCLUSION: Symptoms and CVD events are associated with a high burden on AF patients and healthcare systems throughout Europe.

BACKGROUND: Coronary computed tomography angiogram (CCTA) is a crucial tool for diagnosing CAD, but its impact on altering preventive medications is not well-documented. This systematic review aimed to compare changes in aspirin and statin therapy following CCTA and functional stress testing in patients with suspected CAD, and in those underwent CCTA when stratified by the presence/absence of plaque. RESULTS: Eight studies involving 42,812 CCTA patients and 64,118 cardiac stress testing patients were analyzed. Compared to functional testing, CCTA led to 66 â% more changes in statin therapy (pooled RR, 95 â% CI [1.28-2.15]) and a 74 â% increase in aspirin prescriptions (pooled RR, 95 â% CI [1.34-2.26]). For medication modifications based on CCTA results, 13 studies (47,112 patients with statin data) and 11 studies (12,089 patients with aspirin data) were included. Patients with any plaque on CCTA were five times more likely to use or intensify statins compared to those without CAD (pooled RR, 5.40, 95 â% CI [4.16-7.00]). Significant heterogeneity remained, which decreased when stratified by diabetes rates. Aspirin use increased eightfold after plaque detection (pooled RR, 8.94 [95 â% CI, 4.21-19.01]), especially with obstructive plaque findings (pooled RR, 9.41, 95 â% CI [2.80-39.02]). CONCLUSION: In conclusion, CCTA resulted in higher changes in statin and aspirin therapy compared to cardiac stress testing. Detection of plaque by CCTA significantly increased statin and aspirin therapy.

BACKGROUND: Sodium tanshinone IIA sulfonate injection (STS) is widely used in the clinical treatment of coronary heart disease angina pectoris (CHDAP). This article systematically summarizes and evaluates the available evidence for STS in the treatment of AP, and assess its quality. METHODS: Two researchers searched and extracted 8 databases for systematic reviews (SRs)/meta-analyses (MAs), and independently assessed the methodological quality, risk of bias, reporting quality, and quality of evidence of SRs/MAs included in randomized controlled trials (RCTs). Tools used included the Assessment of Multiple Systematic Reviews 2 (AMSTAR-2), the risk of bias in systematic (ROBIS) scale, the list of Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA), and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. RESULTS: This overview includes 11 SRs/MAs that use quantitative calculations to comprehensively evaluate various efficacies of STS in AP intervention. The methodological quality, reporting quality, risk of bias, and quality of evidence for outcome measures of SRs/MAs were all unsatisfactory. All SRs/MAs are of low quality according to the results of the AMSTAR-2 assessment, and only a small number of SRs/MAs were assessed as low risk of bias based on the results of the ROBIS assessment, and none of the SRs/MAs has been fully reported on the checklist. According to GRADE system, 33 outcomes were extracted from the included SRs/MAs for evaluation, of which 12 were rated as moderate-quality evidence, 7 as low-quality evidence, and 14 as very low-quality evidence. Limitations included the lack of essential items such as protocol registration, screening of duplicate studies, provision of a list of excluded studies and assessment of publication bias. CONCLUSION: Tanshinone IIA Sulfonate Sodium Injection may be an effective and safe treatment method. However, further standardized, comprehensive SRs/MAs and RCTs are needed to provide evidence-based medical support.

BACKGROUND: The financial burden linked to the diagnosis and treatment of patients with chest pain on the health care system is considerable. Angina and nonobstructive coronary artery disease (ANOCA) is common, associated with adverse cardiovascular events, and may lead to repeat testing or hospitalizations. Diagnostic certainty can be achieved in patients with ANOCA using coronary reactivity testing (CRT); however, its financial effect on the patient has not been studied. Our goal was to assess the effect of CRT on health care-related cost in patients with ANOCA. METHODS: Patients with ANOCA who underwent diagnostic coronary angiography (CAG) and CRT (CRT group) were matched to controls who had similar presentation but only underwent a CAG without CRT (CAG group). Standardized inflation-adjusted costs were collected and compared between the 2 groups on an annual basis for 2 years post the index date (CRT or CAG). RESULTS: Two hundred seven CRT and 207 CAG patients were included in the study with an average age of 52.3±11.5 years and 76% females. The total cost was significantly higher in the CAG group as compared with the CRT group ($37 804 [$26 933-$48 674] versus $13 679 [$9447-$17 910]; P<0.001). When costs are itemized and divided based on the Berenson-Eggers Type of Service categorization, the largest cost difference occurred in imaging (any type, including CAG; P<0.001), procedures (eg, percutaneous coronary intervention/coronary artery bypass grafting/thrombectomy) (P=0.001), and test (eg, blood tests, EKG; P<0.001). CONCLUSIONS: In this retrospective observational study, assessment of CRT in patients with ANOCA was associated with significantly reduced annual total costs and health care utilization. Therefore, the study may support the integration of CRT into clinical practice.

BACKGROUND: Ventricular septal rupture (VSR) is a rare but well-known mechanical consequence of an acute myocardial infarction (AMI). Even in the later stages of re-perfusion therapy, the result of VSR remains poor. Our aim is to assess the site and size of VSR in relation to the severity of cardiac failure. METHODS: From January 2016 to December 2022, a total of 71 patients with a diagnosis of post-myocardial infarction VSR were admitted to the First Affiliated Hospital of Zhengzhou University, Zhengzhou, China. Data records were retrospectively included in this registry. In all patients, clinical and echocardiographic data were gathered, and statistical analyses were performed. RESULTS: A total of 71 consecutive patients (mean age: 66.27 ± 8.88 years); 50.7% male, 49.3% female, with (M:F) ratio of almost (1:1). Left ventricular ejection fraction (LVEF) was (48.55 ± 10.44%) on echocardiography, and apical VSR was the most common site (69.0%). Overall, the VSD site was strongly related to the VSD size (p = .016), LVEF (p = .012), AMI site (p = .001), and affected coronary vessel (p = .004). Prodromal angina (p = .041), intra-aortic balloon pump (p = .002), affected coronary vessels (p = .020), pro-BNP (p = .000), and LVEF (p = .017) were predictors of the severity of heart failure. CONCLUSIONS: Diabetes mellitus is a common risk factor for post-myocardial infarction VSR. VSR site and size had no relation to the severity of heart failure. A presentation with prodromal angina predicted severe heart failure and a worse prognosis.

BACKGROUND: MicroRNAs (miRNAs) are noncoding RNAs involved in post-transcriptional genetic regulation with a proposed role in intercellular communication. miRNAs are considered promising biomarkers in ischemic heart disease. Invasive physiological evaluation allows a precise assessment of each affected coronary compartment. Although some studies have associated the expression of circulating miRNAs with invasive physiological indexes, their global relationship with coronary compartments has not been assessed. Here, we will evaluate circulating miRNAs profiles according to the coronary pattern of the vascular compartment affectation. STUDY AND DESIGN: This is an investigator-initiated, multicentre, descriptive study to be conducted at three centres in Spain (NCT05374694). The study will include one hundred consecutive patients older than 18 years with chest pain of presumed coronary cause undergoing invasive physiological evaluation, including fractional flow reserve (FFR) and index of microvascular resistance (IMR). Patients will be initially classified into four groups, according to FFR and IMR: macrovascular and microvascular affectation (FFR≤0.80 / IMR≥25), isolated macrovascular affectation (FFR≤0.80 / IMR<25), isolated microvascular affectation (FFR>0.80 / IMR ≥25) and normal coronary indexes (FFR>0.80 / IMR<25). Patients with isolated microvascular affectation or normal indexes will also undergo the acetylcholine test and may be reclassified as a fifth group in the presence of spasm. A panel of miRNAs previously associated with molecular mechanisms linked to chronic coronary syndrome will be analysed using RT-qPCR. CONCLUSIONS: The results of this study will identify miRNA profiles associated with patterns of coronary affectation and will contribute to a better understanding of the mechanistic pathways of coronary pathology.

Coronary collateral circulation (CCC) has been shown to have a prognostic role in acute myocardial infarction (MI). We aimed to identify factors associated with CCC development in patients with acute myocardial ischemia. In the present analysis, 673 consecutive patients aged 27 - 94 years (64.7±11.48) with acute coronary syndrome (ACS), who underwent coronary angiography within the first 24 hours after symptom onset were included. Baseline data, including sex, age, cardiovascular risk factors, medication, antecedent angina, prior coronary revascularization, EF%, blood pressure levels were obtained from patient medical records. The study individuals were divided into two groups: patients with Rentrop grade 0 to 1 were classified as the poor collateral group (456 patients), and the patients with grade 2 to 3 - as the good collateral group (217 patients). Prevalence of good collaterals of 32% was found. Odds of good collateral circulation increases with higher eosinophil count - OR=17.36 (95% CI: 3.25-92.86); history of MI (OR=1.76; 95% CI:1.13-2.75); multivessel disease - OR=9.78 (95% CI: 5.65-16.96); culprit vessel stenosis - OR=3.91 (95% CI: 2.35-6.52); presence of angina pectoris > 5 years - OR=5.55 (95% CI:2.66-11.57) and decreases with high N/L- OR=0.37 (95% CI:0.31-0.45) and male gender - OR=0.44 (95% CI:0.29-0.67). High N/L is a predictor of poor collateral circulation, with 68.4 sensitivity and 72.8% specificity (cutoff: 2.73*109). Relative chance of good collateral circulation increases with the higher number of eosinophils, presence of angina pectoris with duration of more than 5 years, history of past myocardial infarction, culprit vessel stenosis, multivessel disease, and reduces if patient is male and has high N/L ratio. Peripheral blood parameters may serve as an additional simple risk assessment tool in ACS patients.

BACKGROUND: In 2016, the National Institute for Health and Care Excellence Clinical Guideline Number 95 ("Chest pain of recent onset") (CG95) recommended coronary computed tomography angiography (CCTA) as the first-line test for possible angina. OBJECTIVES: The purpose of this study was to determine the impact of temporal trends in imaging use on outcomes for coronary artery disease (CAD) following the CG95 recommendations. METHODS: Investigations from 2012 to 2018 were extracted from a national database and linked to hospital admission and mortality registries. Growth rates were adjusted for population size, with image modality use, cardiovascular hospital admissions, and mortality compared using Kendall's rank correlation. The impact of CG95 was assessed using an interrupted time-series analysis. RESULTS: A total of 1,909,314 investigations for CAD were performed, with an annualized per capita growth of 4.8%. Costs were £0.35 million/100,000 population/year with an increase of 2.8%/year mirroring inflation (2.5%/year). CG95 was associated with a rise in CCTA (exp[ß]: 1.10; 95% CI: 1.03-1.18), no change in myocardial perfusion imaging, and a potential modest fall (exp[ß]: 0.997; 95% CI: 0.993-1.00]) in invasive coronary angiography. There was an apparent trend between computed tomography angiography growth and invasive catheter angiography reduction across regions (Kendall Tau: -0.19; P = 0.08). CCTA growth was associated with a reduction in cardiovascular mortality (Kendall Tau: -0.21; P = 0.045), and ischemic heart disease deaths (Kendall Tau: -0.22; P = 0.042), with an apparent trend with reduced all-cause mortality (Kendall Tau: -0.19; P = 0.07). CONCLUSIONS: Imaging investigations for CAD are increasing. Greater regional increases in CCTA were associated with fewer hospitalizations for myocardial infarction and a more rapid decline in CAD mortality.

Coronary artery disease (CAD) is a serious health problem that causes a considerable number of mortality in a number of affluent nations throughout the world. The estimated death encountered in many developed countries includes including Pakistan, reached 111,367 and accounted for 9.87% of all deaths, despite the mortality rate being around 7.2 million deaths per year, or 12% of all estimated deaths accounted annually around the globe, with improved health systems. Atherosclerosis progressing causes the coronary arteries to become partially or completely blocked, which results in CAD. Additionally, smoking, diabetes mellitus, homocystinuria, hypertension, obesity, hyperlipidemia, and psychological stress are risk factors for CAD. The symptoms of CAD include angina which is described as a burning, pain or discomfort in the chest, nausea, weakness, shortness of breath, lightheadedness, and pain or discomfort in the arms or shoulders. Atherosclerosis and thrombosis are the 2 pathophysiological pathways most frequently involved in acute coronary syndrome (ACS). Asymptomatic plaque disruption, plaque bleeding, symptomatic coronary blockage, and myocardial infarction are the prognoses for CAD. In this review, we will focus on medicated therapy which is being employed for the relief of angina linked with CAD including antiplatelet medicines, nitrates, calcium antagonists, blockers, catheterization, and the frequency of recanalized infarct-related arteries in patients with acute anterior wall myocardial infarction (AWMI). Furthermore, we have also enlightened the importance of biomarkers that are helpful in the diagnosis and management of CAD.

BACKGROUND: FFRCT assesses the functional significance of lesions seen on CTCA, and may be a more efficient approach to chest pain evaluation. The FORECAST randomized trial found no significant difference in costs within the UK National Health Service, but implications for US costs are unknown. The purpose of this study was to compare costs in the FORECAST trial based on US healthcare cost weights, and to evaluate factors affecting costs. METHODS: Patients with stable chest pain were randomized either to the experimental strategy (CTCA with selective FFRCT), or to standard clinical pathways. Pre-randomization, the treating clinician declared the planned initial test. The primary outcome was nine-month cardiovascular care costs. RESULTS: Planned initial tests were CTCA in 912 patients (65%), stress testing in 393 (28%), and invasive angiography in 94 (7%). Mean US costs did not differ overall between the experimental strategy and standard care (cost difference +7% (+$324), CI -12% to +26%, p â= â0.49). Costs were 4% lower with the experimental strategy in the planned invasive angiography stratum (p for interaction â= â0.66). Baseline factors independently associated with costs were older age (+43%), male sex (+55%), diabetes (+37%), hypertension (+61%), hyperlipidemia (+94%), prior angina (+24%), and planned invasive angiography (+160%). Post-randomization cost drivers were coronary revascularization (+348%), invasive angiography (267%), and number of tests (+35%). CONCLUSIONS: Initial evaluation of chest pain using CTCA with FFRCT had similar US costs as standard care pathways. Costs were increased by baseline coronary risk factors and planned invasive angiography, and post-randomization invasive procedures and the number of tests. Registration at ClinicalTrials.gov (NCT03187639).

BACKGROUND: Coronary heart disease (CHD) is a cardiovascular disease caused by myocardial ischemia. In China, safflor yellow and artemisinin-based combination therapies have been extensively used to treat angina pectoris. METHODS: Efficacies were provided by a network meta-analysis following the PRISMA 2020 checklist. Cost-effectiveness analysis was based on patient perspectives. Two-way and probabilistic sensitivity analyses were conducted to assess the robustness of the study results. RESULTS: Conventional treatment combined with safflower is a better choice against angina pectoris. Sensitivity analysis showed that the model was sensitive to the treatment efficacy rather than the drug cost. CONCLUSION: Conventional treatment combined with safflower injection is suggested to treat angina pectoris. Low molecular weight heparin or compound Danshen-dropping pills can be used to increase the recovery rate of angina pectoris, according to conventional treatment combined with safflower injection.

INTRODUCTION: Non-obstructive coronary arteries (NOCA) are present in 39.7% to 62.4% of patients who undergo elective angiography. Coronary microcirculation (<400 µm) is not visible on angiography therefore functional assessment, invasive or noninvasive plays a prior role to help provide a more personalized diagnosis of angina. AREA COVERED: In this review, we revisit the pathophysiology, clinical importance, and invasive assessment of the coronary microcirculation, and discuss angiography-derived indices of microvascular resistance. A comprehensive literature review over four decades is also undertaken. EXPERT OPINION: The coronary microvasculature plays an important role in flow autoregulation and metabolic regulation. Invasive assessment of microvascular resistance is a validated modality with independent prognostic value, nevertheless, its routine application is hampered by the requirement of intravascular instrumentation and hyperemic agents. The angiography-derived index of microvascular resistance has emerged as a promising surrogate in pilot studies, however, more data are needed to validate and compare the diagnostic and prognostic accuracy of different equations as well as to illustrate the relationship between angiography-derived parameters for epicardial coronary arteries and those for the microvasculature.

OBJECTIVES: To assess the feasibility and acceptability, and additionally to preliminarily evaluate, the effectiveness and safety of an accelerated diagnostic chest pain pathway in rural general practice using point-of-care troponin to identify patients at low risk of acute myocardial infarction, avoiding unnecessary patient transfer to hospital and enabling early discharge home. DESIGN: A prospective observational pilot evaluation. SETTING: Twelve rural general (family) practices in the Midlands region of New Zealand. PARTICIPANTS: Patients aged ≥18 years who presented acutely to rural general practice with suspected ischaemic chest pain for whom the doctor intended transfer to hospital for serial troponin measurement. OUTCOME MEASURES: The proportion of patients managed using the low-risk pathway without transfer to hospital and without 30-day major adverse cardiac event (MACE); pathway adherence; rate of 30-day MACE; patient satisfaction with care; and agreement between point-of-care and laboratory measured troponin concentrations. RESULTS: A total of 180 patients were assessed by the pathway. The pathway classified 111 patients (61.7%) as low-risk and all were managed in rural general practice with no 30-day MACE (0%, 95% CI 0.0% to 3.3%). Adherence to the low-risk pathway was 95.5% (106 out of 111). Of the 56 patients classified as non-low-risk and referred to hospital, 9 (16.1%) had a 30-day MACE. A further 13 non-low-risk patients were not transferred to hospital, with no events. The sensitivity of the pathway for 30-day MACE was 100.0% (95% CI 70.1% to 100%). Of low-risk patients, 94% reported good to excellent satisfaction with care. Good concordance was observed between point-of-care and duplicate laboratory measured troponin concentrations. CONCLUSIONS: The use of an accelerated diagnostic chest pain pathway incorporating point-of-care troponin in a rural general practice setting was feasible and acceptable, with preliminary results suggesting that it may safely and effectively reduce the urgent transfer of low-risk patients to hospital.

The patient reported angina measurement with the Seattle Angina Questionnaire (SAQ) has shown to have prognostic implications and became an endpoint in clinical trials. Our objective was to study physician-reported and SAQ severity with the total coronary atherosclerotic burden as assessed by 4 angiographic scores. We prospectively analyzed data of consecutive patients scheduled for coronary angiography or percutaneous coronary intervention. The Canadian Cardiovascular Society (CCS) angina categories was used as physician-reported angina. SAQ domains were categorized as severe (0 to 24), moderate 25 to 75 and mild angina (>75). All angina assessments were done before coronary angiography. Gensini, Syntax, Friesinger, and Sullivan angiographic scores were used for total atherosclerotic burden quantification: 261 patients were included in the present analysis. The median age was 66.0 (59.0 to 71.8) years, 53.6% were male and 43.7% had diabetes. The median SYNTAX score was 6.0 (0 to 18.0). The worse the symptoms of CCS categories, the more severe was the atherosclerotic burden in all angiographic scores: SYNTAX (pâ¯=â¯0.01); Gensini (p <0.01); Friesinger (p = 0.02) and Sullivan (pâ¯=â¯0.03). Conversely, SAQ domains were not able to discriminate the severity of CAD in any of the scores. The only exception was the severe SAQ quality of life that had worse Gensini score than the mild SAQ quality of life (pâ¯=â¯0.04). In conclusion, CCS angina categories are related to the total atherosclerotic burden in coronary angiography, by all angiographic scores. SAQ domains should be used as a measure of patient functionality and quality of life but not as a measure of CAD severity.

Spontaneous coronary artery dissection (SCAD) can present with various clinical symptoms, including chest pain, syncope, and sudden cardiac death, particularly in those without atherosclerotic risk factors. In this contemporary analysis, we aimed to identify the causes and predictors of 30-day hospital readmission in SCAD patients. We utilized the latest Nationwide Readmissions Database from 2016 - 2017 to identify patients with a primary discharge diagnosis of SCAD. The primary outcome was 30-day readmission. Among 795 patients admitted with a principal discharge diagnosis of SCAD, 85 (11.3%) were readmitted within 30 days of discharge from index admission (69.8% women, mean age of 54.3 ± 0.8). More than half of the readmissions (57%) were cardiac-related readmissions. Common cardiac causes for 30-day hospital readmission were acute coronary syndrome (27.3%), chest pain/unspecified angina (24.6%), heart failure (17.5%), and recurrent SCAD (8.3%). In conclusion, we found that following hospitalization for SCAD, almost one-tenth of patients were readmitted within 30 days, largely due to cardiac cause . Risk stratifying patients with SCAD, identifying high-risk features or atypical phenotypes of SCAD, and using appropriate management strategies may prevent hospital readmissions and reduce healthcare-related costs. Further studies are warranted to confirm these causes of readmission in SCAD patients.
