RESUMO

Regular Finnish sauna use is associated with a reduced risk of cardiovascular mortality. However, physiological mechanisms underlying this association remain unknown. This study determined if an 8-wk Finnish sauna intervention improves peripheral endothelial function, microvascular function, central arterial stiffness, and blood pressure in adults with coronary artery disease (CAD). Forty-one adults (62 ± 6 yr, 33 men/8 women) with stable CAD were randomized to 8 wk of Finnish sauna use (n = 21, 4 sessions/wk, 20-30 min/session, 79°C, 13% relative humidity) or a control intervention (n = 20, lifestyle maintenance). Brachial artery flow-mediated dilation (FMD), carotid-femoral pulse wave velocity (cf-PWV), total (area under the curve) and peak postocclusion forearm reactive hyperemia, and blood pressure (automated auscultation) were measured before and after the intervention. After the sauna intervention, resting core temperature was lower (-0.27°C [-0.54, -0.01], P = 0.046) and sweat rate during sauna exposure was greater (0.3 L/h [0.1, 0.5], P = 0.003). The change in brachial artery FMD did not differ between interventions (control: 0.07% [-0.99, +1.14] vs. sauna: 0.15% [-0.89, +1.19], interaction P = 0.909). The change in total (P = 0.031) and peak (P = 0.024) reactive hyperemia differed between interventions due to a nonsignificant decrease in response to the sauna intervention and an increase in response to control. The change in cf-PWV (P = 0.816), systolic (P = 0.951), and diastolic (P = 0.292) blood pressure did not differ between interventions. These results demonstrate that four sessions of Finnish sauna bathing per week for 8 wk does not improve markers of vascular health in adults with stable CAD.NEW & NOTEWORTHY This study determined if unsupervised Finnish sauna bathing for 8 wk improves markers of vascular health in adults with coronary artery disease. Finnish sauna bathing reduced resting core temperature and improved sweating capacity, indicative of heat acclimation. Despite evidence of heat acclimation, Finnish sauna bathing did not improve markers of endothelial function, microvascular function, arterial stiffness, or blood pressure.

RESUMO

OBJECTIVE: The first clinical manifestation of coronary artery disease (CAD) varies widely from unheralded myocardial infarction (MI) to mild, incidentally detected disease. The primary objective of this study was to quantify the association between different initial CAD diagnostic classifications and future heart failure. METHODS: This retrospective study incorporated the electronic health record of a single integrated health care system. Newly diagnosed CAD was classified into a mutually exclusive hierarchy as MI, CAD with coronary artery bypass graft (CABG), CAD with percutaneous coronary intervention, CAD only, unstable angina, and stable angina. An acute CAD presentation was defined when the diagnosis was associated with a hospital admission. New heart failure was identified after the CAD diagnosis. RESULTS: Among 28 693 newly diagnosed CAD patients, initial presentation was acute in 47% and manifested as MI in 26%. Within 30 days of CAD diagnosis, MI [hazard ratio (HR) = 5.1; 95% confidence interval: 4.1-6.5] and unstable angina (3.2; 2.4-4.4) classifications were associated with the highest heart failure risk (compared to stable angina), as was acute presentation (2.9; 2.7-3.2). Among stable, heart failure-free CAD patients followed on average 7.4 years, initial MI (adjusted HR = 1.6; 1.4-1.7) and CAD with CABG (1.5; 1.2-1.8) were associated with higher long-term heart failure risk, but an initial acute presentation was not (1.0; 0.9-1.0). CONCLUSION: Nearly 50% of initial CAD diagnoses are associated with hospitalization, and these patients are at high risk of early heart failure. Among stable CAD patients, MI remained the diagnostic classification associated with the highest long-term heart failure risk, however, having an initial acute CAD presentation was not associated with long-term heart failure.

RESUMO

BACKGROUND: Treatment of unprotected severely calcified left main coronary artery (LMCA) disease is a complex interventional procedure. Intravascular lithotripsy (IVL) and rotational atherectomy (RA) are safe and effective methods of treating coronary calcification in the non-LMCA setting. This retrospective analysis assessed the feasibility of IVL versus RA in unprotected LMCA disease. METHODS: We analyzed IVL and RA procedures performed at a large tertiary hospital in the Northeast of England from January 1, 2019 to April 31, 2022. Major safety and efficacy endpoints were procedural and angiographic success, defined by stent delivery with <50 % residual stenosis and without clinical or angiographic complications, respectively. Another important clinical endpoint was the composite of major adverse cardiac events (MACE) at 1 year. RESULTS: From 242 patients, 44 had LMCA IVL, 81 had LMCA RA and 117 had non-LMCA IVL. Patients with LMCA disease were older and more likely to have aortic stenosis. IVL was a second-line or bailout technique in 86.4 % LMCA and 92.2 % non-LMCA cases. Procedural and angiographic success rates were ≥ 84 % across all groups (p > 0.05). In 3 LMCA IVL and 3 LMCA RA cases arrhythmias and cardiac tamponade complicated the procedures respectively. At 1 year, MACE occurred in 10/44 (22.7 %) LMCA IVL, 16/81 (19.8 %) LMCA RA and 25/117 (21.4 %) cases (p > 0.05). CONCLUSION: In our single center retrospective analysis, IVL is feasible in unprotected calcified LMCA as a second-line and third-line adjuvant calcium modification technique. Its use in unprotected calcified LMCA disease should be formalized with the undertaking of large randomized controlled trials.

RESUMO

BACKGROUND: Twenty percent to 40% of patients are affected by angina after percutaneous coronary intervention (PCI), which is associated with anxiety, depression, impaired physical function, and reduced quality of life. Understanding patient and procedural factors associated with post-PCI angina may inform alternative approaches to treatment. METHODS: Two hundred thirty patients undergoing PCI completed the Seattle Angina Questionnaire (SAQ-7) and European quality of life-5 dimension-5 level (EQ-5D-5L) questionnaires at baseline and 3 months post-PCI. Patients received blinded intracoronary physiology assessments before and after stenting. A post hoc analysis was performed to compare clinical and procedural characteristics among patients with and without post-PCI angina (defined by follow-up SAQ-angina frequency score <100). RESULTS: Eighty-eight of 230 patients (38.3%) reported angina 3 months post-PCI and had a higher incidence of active smoking, atrial fibrillation, and history of previous myocardial infarction or PCI. Compared with patients with no angina at follow-up, they had lower baseline SAQ summary scores (69.48±24.12 versus 50.20±22.59, P<0.001) and EQ-5D-5L health index scores (0.84±0.15 versus 0.69±0.22, P<0.001). Pre-PCI fractional flow reserve (FFR) was lower among patients who had no post-PCI angina (0.56±0.15 versus 0.62±0.13, P=0.003). Percentage change in FFR after PCI had a moderate correlation with angina frequency score at follow-up (r=0.36, P<0.0001). Patients with post-PCI angina had less improvement in FFR (43.1±33.5% versus 67.0±50.7%, P<0.001). There were no between-group differences in post-PCI FFR, coronary flow reserve, or corrected index of microcirculatory resistance. Patients with post-PCI angina had lower SAQ-summary scores (64.01±22 versus 95.16±8.72, P≤0.001) and EQ-5D-5L index scores (0.69±0.26 versus 0.91±0.17, P≤0.001) at follow-up. CONCLUSIONS: Larger improvements in FFR following PCI were associated with less angina and better quality of life at follow-up. In patients with stable symptoms, intracoronary physiology assessment can inform expectations of angina relief and quality of life improvement after stenting and thereby help to determine the appropriateness of PCI.

RESUMO

BACKGROUND Coronary artery perforation is a rare complication of percutaneous coronary intervention for coronary artery occlusion. This report is of 2 cases of coronary artery perforation during percutaneous coronary intervention that were managed successfully using injection of combined Histoacryl (n-Butyl-2-Cyanoacrylate) and Lipiodol (ethiodized oil). CASE REPORT Case 1 was a 51-year-old man with a past medical history of hypertension, dyslipidemia, and multivessel coronary disease. He was admitted to our hospital with inferior wall myocardial infarction, and a stent was placed in the proximal right coronary artery. He also had chronic total occlusion (CTO) of the left anterior descending artery (LAD). The planned LAD CTO intervention was complicated by balloon-induced coronary perforation and was managed successfully with intracoronary injection of Histoacryl-Lipiodol mixtures via microcatheter. He was discharged in stable condition without any serious consequences. Case 2 was a 72-year-old man with underlying hypertension who was admitted to the hospital with diagnosis of unstable angina. The diagnostic angiography showed occlusion of the LAD, CTO of the left circumflex artery, and minor atherosclerosis in right coronary artery. A stent was placed in the mid-LAD without any complications. Subsequently, a planned left circumflex artery CTO intervention was complicated by wire-induced coronary perforation, which was treated successfully with injection of Histoacryl-Lipiodol mixture. The patient was discharged in good condition. CONCLUSIONS Histoacryl and Lipiodol injection was a rapid and effective management method in 2 rare cases of coronary artery perforation during percutaneous coronary intervention.

RESUMO

Management of stable coronary artery disease (CAD) has been based on the assumption that flow-limiting atherosclerotic obstructions are the proximate cause of angina and myocardial ischemia in most patients and represent an important target for revascularization. However, the role of revascularization in reducing long-term cardiac events in these patients has been limited mainly to those with left main disease, 3-vessel disease with diabetes, or decreased ejection fraction. Mounting evidence indicates that nonepicardial coronary causes of angina and ischemia, including coronary microvascular dysfunction, vasospastic disorders, and derangements of myocardial metabolism, are more prevalent than flow-limiting stenoses, raising concerns that many important causes other than epicardial CAD are neither considered nor probed diagnostically. There is a need for a more inclusive management paradigm that uncouples the singular association between epicardial CAD and revascularization and better aligns diagnostic approaches that tailor treatment to the underlying mechanisms and precipitants of angina and ischemia in contemporary clinical practice.

RESUMO

Heavily calcified coronary lesions increase the complexity of percutaneous coronary interventions (PCI) and represent a challenge for interventional cardiologists. They are an important cause of stent underexpansion and poor clinical outcome. Nowadays, there are different dedicated devices which enhance the chances of success. Rotational atherectomy is the first-line modality which permits to cross balloons or stents through severe calcified lesions. However, when circumferential deep calcium plaques exist may not be enough to achieve adequate expansion of these devices. In these cases, the complementary use of intracoronary lithotripsy ("RotaTripsy") can be an effective approach that further modifies the calcified plaque and enables optimal stent implantation. We present the first case series undergoing PCI using "RotaTripsy" technique.

RESUMO

BACKGROUND: It's known that coronary heart disease (CHD) patients after percutaneous coronary intervention (PCI) was significantly associated with anxiety and depression symptoms. Several studies have showed that Xinkeshu tablet (XKS), a kind of Chinese herbal medicine, could effectively improve post-PCI postoperative mood disorders in CHD patients. However, the intensity of evidence has been poor, limiting the further clinical application of XKS to patients above. This systematic review and meta-analysis will assess the effectiveness and safety of studies of XKS in CHD patients with anxiety and depression symptoms after PCI. METHODS: A systematic literature search for articles up to December 2021 will be performed in following electronic databases: PubMed, Embase, the Cochrane Library, China National Knowledge Infrastructure, Chinese Scientific Journals Database Database, Chinese Biomedical Database, Chinese Biomedical Literature Service System, and Wanfang Database. Inclusion criteria are randomized controlled trials of XKS applied on patients with CHD and depression. The primary outcome measures will be CHD-related clinical evaluation (frequency of acute attack angina, severity of angina pectoris, electrocardiographic changes, amount of nitroglycerin) and the scores or reducing fractions of depressive and anxiety measuring scales (the Hospital Anxiety/Depression Scale or other widely used anxiety/depression scale). The safety outcome measures will be adverse events, liver and kidney function. RevMan 5.3 software will be used for data synthesis, sensitivity analysis, subgroup analysis, and risk of bias assessment. A funnel plot will be developed to evaluate reporting bias. Stata 12.0 will be used for meta-regression and Egger tests. We will use the Grading of Recommendations Assessment, Development and Evaluation system to assess the quality of evidence. DISCUSSION: This study will provide a high-quality synthesis of the effects and safety of XKS for CHD patients with anxiety and depression symptoms after PCI. ETHICS AND DISSEMINATION: This systematic review does not require ethics approval and will be submitted to a peer-reviewed journal.Trial registration number PROSPERO CRD42019131346.

RESUMO

Inflammation is a major contributor to the development and progression of atherosclerosis. Interleukin (IL)-33 and IL-37, members of the IL-1 family, modulate inflammation, with IL-33 having a pro-inflammatory effect and IL-37 having anti-inflammatory properties. IL-37 is constitutively expressed at low levels but upregulated in inflammatory contexts. The aim of this study was to evaluate the effect of vitamin D on the expression of IL-33, IL-37, macrophages, and caspase-1 in the neointimal tissue of coronary artery in Yucatan microswine with vitamin D deficient, sufficient, and supplemented status. The intimal injury was induced by balloon angioplasty and stenting in the coronary artery, and tissues were harvested after 6 months. The expression of various proteins of interest was evaluated by immunostaining. Increased expression of IL-33 and IL-37 in the neointimal tissue of the vitamin D deficient, as compared to the sufficient and supplemented microswine, as revealed by histological evaluation and semi-quantitative analysis, suggested the immunomodulatory effect of vitamin D on the expression of IL-33 and IL-37. The minimal expression or absence of IL-33 and IL-37 expression in stented arteries is suggestive of an attenuated inflammatory response in stented arteries, compared to balloon angioplasty. The decreased IL-33 expression in the sufficient and supplemented microswine could be a potential mechanism for controlling the inflammatory process and neointima formation leading to attenuated luminal narrowing of the coronary artery. Overall, these results support supplementation of vitamin D to attenuate inflammation, neointima formation, and restenosis.

RESUMO

Diet quality and statin therapy are established modulators of coronary artery disease (CAD) progression, but their effect on the gastrointestinal tract and subsequent sequelae that could affect CAD progression are relatively unexplored. To address this gap, Ossabaw pigs (N = 32) were randomly assigned to receive isocaloric amounts of a Western-type diet (WD; high in saturated fat, refined carbohydrate, and cholesterol, and low in fiber) or a heart healthy-type diet (HHD; high in unsaturated fat, whole grains, fruits and vegetables, supplemented with fish oil, and low in cholesterol), with or without atorvastatin, for 6 months. At the end of the study, RNA sequencing with 100 base pair single end reads on NextSeq 500 platform was conducted in isolated pig jejunal mucosa. A two-factor edgeR analysis revealed that the dietary patterns resulted in three differentially expressed genes related to lipid metabolism (SCD, FADS1, and SQLE). The expression of these genes was associated with cardiometabolic risk factors and atherosclerotic lesion severity. Subsequent gene enrichment analysis indicated the WD, compared to the HHD, resulted in higher interferon signaling and inflammation, with some of these genes being significantly associated with serum TNF-α and/or hsCRP concentrations, but not atherosclerotic lesion severity. No significant effect of atorvastatin therapy on gene expression, nor its interaction with dietary patterns, was identified. In conclusion, Western and heart healthy-type dietary patterns differentially affect the expression of genes associated with lipid metabolism, interferon signaling, and inflammation in the jejunum of Ossabaw pigs.

RESUMO

BACKGROUND: In India, the use of traditional medicine for health problems is a part of the cultural discourse on treatment, but the introduction of Western medicines has adversely affected their popularity. However, with the rapid spread of chronic diseases like coronary artery disease (CAD), many Indians are reverting to complementary and alternative medicine (CAM) treatments. Although previous literature has identified several motivational factors underlying CAM usage, we know little from the perspective of its practitioners. AIM: The aim of the present study was to investigate the motivations behind the use of CAM treatments among Indian patients with CAD. METHOD: Using semi-structured interviews, we collected data from 15 CAM practitioners and 14 CAD patients utilising CAM treatments alongside conventional biomedical (BM) treatment. We used the Clarke and Braun (2006) method of thematic analysis. RESULT AND CONCLUSION: Our findings suggest that the use of CAM treatments depends on various factors working at multiple levels viz., personal factors, disease' characteristics, perceived treatment characteristics (positive attributes of CAM and negative attributes of BM) and external facilitators. Furthermore, our analysis also identifies the role of two underlining forces-push and pull-in motivating CAD patients to choose CAM treatments. The push force comprises factors that participants found to have a repelling nature, whereas pull forces were regarded as advantageous for CAM usage. Although some reasons behind the usage of CAM treatments according to patients and practitioners were overlapping, both groups also provided many distinct insights into the studied health behaviour.

RESUMO

BACKGROUND: Chelation therapy is promoted and practiced around the world as a form of alternative medicine in the treatment of atherosclerotic cardiovascular disease. It has been suggested as a safe, relatively inexpensive, non-surgical method of restoring blood flow in atherosclerotic vessels. However, there is currently limited high-quality, adequately-powered research informing evidence-based medicine on the topic, specifically regarding clinical outcomes. Due to this limited evidence, the benefit of chelation therapy remains controversial at present. This is an update of a review first published in 2002. OBJECTIVES: To assess the effects of ethylene diamine tetra-acetic acid (EDTA) chelation therapy versus placebo or no treatment on clinical outcomes among people with atherosclerotic cardiovascular disease. SEARCH METHODS: For this update, the Cochrane Vascular Information Specialist searched the Cochrane Vascular Specialised Register, Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase and Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases, the World Health Organization International Clinical Trials Registry Platform and ClinicalTrials.gov trials register to 6 August 2019. We searched the bibliographies of the studies retrieved by the literature searches for further trials. SELECTION CRITERIA: We included studies if they were randomised controlled trials of EDTA chelation therapy versus placebo or no treatment in participants with atherosclerotic cardiovascular disease. The main outcome measures we considered include all-cause or cause-specific mortality, non-fatal cardiovascular events, direct or indirect measurement of disease severity, and subjective measures of improvement or adverse events. DATA COLLECTION AND ANALYSIS: Two review authors independently extracted data and assessed trial quality using standard Cochrane procedures. A third author considered any unresolved issues, and we discussed any discrepancies until a consensus was reached. We contacted study authors for additional information. MAIN RESULTS: We included five studies with a total of 1993 randomised participants. Three studies enrolled participants with peripheral vascular disease and two studies included participants with coronary artery disease, one of which specifically recruited people who had had a myocardial infarction. The number of participants in each study varied widely (from 10 to 1708 participants), but all studies compared EDTA chelation to a placebo. Risk of bias for the included studies was generally moderate to low, but one study had high risk of bias because the study investigators broke their randomisation code halfway through the study and rolled the placebo participants over to active treatment. Certainty of the evidence, as assessed by GRADE, was generally low to very low, which was mostly due to a paucity of data in each outcome's meta-analysis. This limited our ability to draw any strong conclusions. We also had concerns about one study's risk of bias regarding blinding and outcome assessment that may have biased the results. Two studies with coronary artery disease participants reported no evidence of a difference in all-cause mortality between chelation therapy and placebo (risk ratio (RR) 0.97, 95% CI 0.73 to 1.28; 1792 participants; low-certainty). One study with coronary artery disease participants reported no evidence of a difference in coronary heart disease deaths between chelation therapy and placebo (RR 1.02, 95% CI 0.70 to 1.48; 1708 participants; very low-certainty). Two studies with coronary artery disease participants reported no evidence of a difference in myocardial infarction (RR 0.81, 95% CI 0.57 to 1.14; 1792 participants; moderate-certainty), angina (RR 0.95, 95% CI 0.55 to 1.67; 1792 participants; very low-certainty), and coronary revascularisation (RR 0.46, 95% CI 0.07 to 3.25; 1792 participants). Two studies (one with coronary artery disease participants and one with peripheral vascular disease participants) reported no evidence of a difference in stroke (RR 0.88, 95% CI 0.40 to 1.92; 1867 participants; low-certainty). Ankle-brachial pressure index (ABPI; also known as ankle brachial index) was measured in three studies, all including participants with peripheral vascular disease; two studies found no evidence of a difference in the treatment groups after three months after treatment (mean difference (MD) 0.02, 95% CI -0.03 to 0.06; 181 participants; low-certainty). A third study reported an improvement in ABPI in the EDTA chelation group, but this study was at high risk of bias. Meta-analysis of maximum and pain-free walking distances three months after treatment included participants with peripheral vascular disease and showed no evidence of a difference between the treatment groups (MD -31.46, 95% CI -87.63 to 24.71; 165 participants; 2 studies; low-certainty). Quality of life outcomes were reported by two studies that included participants with coronary artery disease, but we were unable to pool the data due to different methods of reporting and varied criteria. However, there did not appear to be any major differences between the treatment groups. None of the included studies reported on vascular deaths. Overall, there was no evidence of major or minor adverse events associated with EDTA chelation treatment. AUTHORS' CONCLUSIONS: There is currently insufficient evidence to determine the effectiveness or ineffectiveness of chelation therapy in improving clinical outcomes of people with atherosclerotic cardiovascular disease. More high-quality, randomised controlled trials are needed that assess the effects of chelation therapy on longevity and quality of life among people with atherosclerotic cardiovascular disease.

RESUMO

BACKGROUND: Although patients with coronary artery disease (CAD) rely increasingly upon percutaneous coronary intervention (PCI), this therapy causes subsequent the complications of myocardial injury. Acupuncture safely protects the heart from ischemic injury; however, the efficacy of acupuncture for periprocedural myocardial injury after PCI remains unclear. METHODS: Seven databases in English and Chinese including PubMed, Web of Science, Cochrane Library, Embase, Chinese Biomedical Literature Database, Chinese National Knowledge Infrastructure, and Wanfang Database will be searched. Randomized controlled trials (RCTs) that use acupuncture to treat PCI-related myocardial injury in patients with CAD, regardless of blinding. The crossover randomized trials will be included, but only the pre-crossover data will be analyzed to avoid carryover effects. We will exclude non-RCTs, qualitative studies, uncontrolled clinical trials, and laboratory studies. The measurement of concentration of cardiac troponin (T or I) and MB isoenzyme of creatine kinase will be used as primary outcome. Postprocedural cardiac function and the major adverse cardiac/cerebrovascular event rate will be assessed as secondary outcome. Relevant data were collected independently by 2 reviewers and the third reviewer was responsible for resolving discrepancies through discussion. The Review Manager V.5.3.3 s will be used to perform the data synthesis and subgroup analysis. DISCUSSION: This systematic review and meta-analysis would provide convincing evidence of various types of acupuncture that specifically focuses on cardioprotective effect of acupuncture on PCI-related myocardial injury.

RESUMO

This study was conducted to assess the effect of an empowerment program on the perceived risk and physical health of patients with coronary artery disease. This randomized clinical trial recruited 84 patients with coronary artery disease admitted to post-cardiac care unit (CCU) wards in Tehran Heart Center in 2017. The study subjects were selected and assessed according to inclusion criteria and assigned to intervention and control groups by block randomization. Both groups completed questionnaires for demographic details and disease history, perceived risk in cardiac patients, and physical health. The Magic Empowerment Program was performed for the intervention group as 3 workshops on 3 successive days. Intervention continued after patients' discharge from the hospital through phone calls once a week for 8 weeks. The perceived risk in cardiac patients and physical health questionnaires were completed for both groups. Postintervention results showed significant differences between the 2 groups in total score of perceived risk (P = .001) and its subscales. The Empowerment Program changed patients' attitudes toward risk-motivating behavior change and improving physical health.

RESUMO

Despite optimal combination of guideline-directed anti-ischemic therapies and myocardial revascularization, a substantial proportion of patients with stable coronary artery disease continues to experience disabling symptoms and is often referred as "no-option." The appraisal of the pathways linking ischemia to symptom perception indicates a complex model of heart-brain interactions in the generation of the subjective anginal experience and inspired novel approaches that may be clinically effective in alleviating the angina burden of this population. Conversely, the prevailing ischemia-centered view of angina, with the focus on traditional myocardial revascularization as the sole option to address ischemia on top of medical therapy, hinders the experimental characterization and broad-scale clinical implementation of strongly needed therapeutic options. The interventionist, often the first physician to establish the diagnosis of refractory angina pectoris (RAP) following coronary angiography, should be aware of the numerous emerging technologies with the potential to improve quality of life in the growing population of RAP patients. This review describes the current landscape and the future perspectives on nonpharmacological treatment technologies for patients with RAP, with a view on the underlying physiopathological rationale and current clinical evidence.

RESUMO

BACKGROUND: Approximately 5% of coronary angiographies detect LMS disease >50%. Recent randomized trials showed PCI has comparable outcomes to coronary artery bypass grafting (CABG) in low or intermediate risk candidates. In clinical practice, PCI is frequently utilized in those with prohibitive surgical risk. We reviewed contemporary national results of percutaneous coronary intervention (PCI) for left main coronary disease (LMS) disease in New Zealand. METHODS: All patients undergoing PCI for LMS disease from 01/09/2014-24/09/2017 were extracted from the All New Zealand Acute Coronary Syndrome-Quality Improvement registry with national dataset linkage, analyzing characteristics and in-hospital outcomes. RESULTS: The cohort included 469 patients, mean age 70.8 ±â€¯10.7 years, male 331 (71%), and the majority 339 (72%) were unprotected LMS. Indications include ST-elevation myocardial infarction (STEMI) 83 (18%) and NSTEMI or unstable angina 229 (49%). Compared with protected LMS, unprotected LMS were more likely to present with an acute coronary syndrome (73% versus 48%, P < 0.001), and to die in-hospital (9.4% versus 3.9%, P = 0.045). In those with unprotected LMS, in-hospital mortality after acute STEMI PCI was higher than for other indications (21.1% versus 6.1%, P < 0.001). Independent predictors of in-hospital death and major adverse cardiovascular events included STEMI, femoral access and worse renal function. CONCLUSION: Our LMS PCI cohort had high mortality rates, especially those presenting with STEMI and an unprotected LMS. This reflects the contemporary real-world practice of LMS PCI being predominantly performed in high risk patients which differs from randomized trial populations, and this should be considered before comparing with CABG outcomes.

RESUMO

Stent underexpansion is frequently observed in calcified coronary lesions and increases the risk of future adverse cardiac events. Current plaquemodification techniques might not be suitable when calcium deposition is circumferential and deep inside the vessel wall. We report a case during which coronary lithoplasty was used as an adjuvant therapy to improve severe stent underexpansion after failed atherectomy and high-pressure non-compliant balloon dilatations.

RESUMO

A 75-year-old, married man was diagnosed with coronary artery disease (CAD) [severe triple vessel disease (TVD)] in the 2nd week, June-2018. The physician advised him to undergo conventional medication and coronary artery bypass graft. Since the patient refused to undergo surgery he was admitted in our hospital and underwent yoga and naturopathy-based lifestyle modification (YNLM) along with conventional medicines for 16 weeks [12 weeks of intensive care at inpatient department and 4 weeks at outpatient department (OPD)]. After 16 weeks, the patient visited our OPD once/twice a month for 6 months. An increase in left ventricular ejection fraction from 35 to 48%; and a reduction in weight from 77.5 to 71-kg, and BMI from 26.60 to 24-kg/m2 were observed after 6 months of follow-up compared with baseline. Thus, YNLM might be considered as an adjuvant in reducing risk factor and in improving left ventricular systolic dysfunction in patients with CAD (severe-TVD). However, further studies are required to establish the efficacy of YNLM for CAD.

RESUMO

BACKGROUND: Among stented patients with atrial fibrillation, double therapy with a novel oral anticoagulant plus single antiplatelet therapy (SAPT) reduces bleeding or cardiovascular rehospitalizations compared with a vitamin K antagonist (VKA) based triple therapy regimen. A recent study demonstrated that apixaban based double therapy reduced bleeding compared with VKA based double therapy. However, it remains unknown whether rivaroxaban based double therapy is superior to a VKA based double therapy. METHODS: Patient with stented atrial fibrillation (n=2124) were randomized to 3 groups: rivaroxaban 15 mg od plus a P2Y12 inhibitor (Group 1, n=709); rivaroxaban 2.5 mg bid plus dual antiplatelet therapy (DAPT; Group 2, n=709); and warfarin plus DAPT (Group 3, n=706). Before randomization, subjects were stratified according to a prespecified duration of DAPT (1, 6, or 12 months). After the prespecified DAPT duration, subjects in Group 2 were switched to rivaroxaban 15 mg plus low dose aspirin, and those in Group 3 were switched to VKA plus low dose aspirin. The Wei, Lin, and Weissfeld time to multiple events method was used to compare the occurrence of all bleeding and cardiovascular rehospitalizations among subjects on a novel oral anticoagulant versus VKA based double therapy. RESULTS: A total of 906 subjects were prespecified to a 1 or 6 months DAPT duration and received at least one dose of study drug. Twenty subjects (3.3%) assigned to novel oral anticoagulant+SAPT, and 15 (5.1%) subjects assigned to VKA+SAPT experienced multiple rehospitalizations. In total, 124 (20.3%) events occurred among subjects on novel oral anticoagulant+SAPT compared with 87 (29.6%) among subjects on VKA+SAPT (hazard ratio=0.65 [95% CI, 0.45-0.93], P=0.008). CONCLUSIONS: Among stented patients with atrial fibrillation, rivaroxaban plus SAPT was superior to warfarin plus SAPT in lowering total bleeding and cardiovascular rehospitalization.
