RESUMO
Bayesian network Meta-analysis was employed to compare the efficacy of different oral Chinese patent medicines in treating type 2 diabetes mellitus with angina pectoris of coronary heart disease. Randomized controlled trial(RCT) of oral Chinese patent medicines in treating type 2 diabetes mellitus complicated with angina pectoris of coronary heart disease were retrieved from 8 Chinese and English databases including CNKI, Wanfang, VIP, SinoMed, EMbase, PubMed, Cochrane Library, and Web of Science with the time interval from inception to November 2022. The BUGSnet package in R 4.2.1 was used to conduct Meta-analysis. A total of 45 RCTs were included, involving 4 727 patients and 7 oral Chinese patent medicines. Network Meta-analysis showed that the conventio-nal western medicine combined with Chinese patent medicines improved the outcome indicators. Shexiang Baoxin Pills + conventional western medicine had the best effect on reducing the incidence of adverse cardiovascular events, and Yixinshu Capsules + conventional western medicine on reducing the frequency and duration of angina pectoris. The conventional western medicine combined with oral Chinese patent medicines can reduce blood glucose indicators. Yindan Xinnaotong Soft Capsules + conventional western medicine had the best effect on reducing fasting blood glucose(FBG), 2 hours postprandial blood glucose(PBG), and glycosylated hemoglobin(HbA1c). The conventional western medicine combined with oral Chinese patent medicines can reduce blood lipid indicators. Yixinshu Capsules + conventional western medicine had the best effect on reducing total cholesterol(TC) and low density lipoprotein-cholesterol(LDL-C), and Yindan Xinnaotong Soft Capsules + conventional western medicine on reducing triglyceride(TG). Current evidence suggests that the patients with type 2 diabetes mellitus complicated with angina pectoris of coronary heart disease could reasonably choose oral Chinese patent medicines on the basis of routine antiplatelet, anticoagulant, hypoglycemic, and antihypertensive therapies, which could reduce the incidence of adverse cardiovascular events, alleviate the symptoms of angina pectoris, and reduce the glucose and lipid metabolism indicators. Shexiang Baoxin Pills + conventional treatment and Yixinshu Capsules + conventional western medicine have better effect on angina pectoris, Yindan Xinnaotong Soft Capsules + conventional western medicine on lowering blood glucose, and Yindan Xinnaotong Soft Capsules + conventional western medicine and Yixinshu Capsules + conventional western medicine on reducing blood lipid. Due to the lack of direct comparative results between Chinese patent medicines and other factors, high-quality studies remain to be carried out for further verification.

BACKGROUND: Coronary heart disease combined with depression is 1 of the 2 major diseases affecting physical and mental health. It has become a hot spot at the intersection of psychiatry and internal medicine. Most doctors call double heart medicine, which has a high incidence rate and a low diagnostic rate. Clinical research shows that Shugan Jieyu Decoction (SJD) has a better curative effect, increased safety, and fewer adverse reactions, but it lacks systematic evaluation. This study aims to integrate clinical data through network meta-analysis and provide more evidence-based medical evidence for clinical medication. METHODS: We searched 8 electronic databases: China knowledge network database, Wanfang, VIP, SinoMed, PubMed, Embase, WebofScience, Cochrane Library, and selected 22 randomized controlled trials from January 2012 to January 2022. The common primary endpoint was the relief of angina pectoris and the improvement of depression. Two researchers used Endnote9.1 software to conduct literature screening and information extraction according to the developed nano-passage standard, used Cochrane collaborative tool to evaluate the bias risk in the experiment, and then used RevMan5.3 software to assess the literature and data analysis synthesis. RESULTS: In 1908 patients with coronary heart disease and depression, the total effective rate of SJD in the treatment of angina pectoris was 3.49 (95% confidence interval, 1.93-6.29), as well as the network meta-analysis of improving depressive symptoms, anxiety, depression scores (SAS, SDS) and quality of life scores (HAMD), and reducing the indicators related to CPR and homocysteine. CONCLUSION: The analysis of this study shows that SJD can reduce the frequency of angina pectoris in patients with coronary heart disease and depression, alleviate anxiety and depression, provide a reference basis for clinical treatment, and select more effective intervention therapy.

BACKGROUND: The morbidity and mortality of coronary heart disease (CHD) has remained high, which greatly increases people's economic burden. Several studies have showed that Tiaogan formula (TGF), as a kind of Chinese herbal medicine, was of benefit to relieving angina pectoris symptoms and improving the quality of life for CHD patients. However, the intensity of evidence has been poor, limiting the further clinical application of TGF to CHD. This systematic review and meta-analysis will assess the effectiveness and safety of studies of TGF in CHD patients. METHODS: A systematic search for literature up to December 2022 will be conducted in following public electronic databases: PubMed, Embase, the Cochrane Library, China National Knowledge Infrastructure, Chinese Scientific Journals Database Database, and Wanfang Database. Inclusion criteria are randomized controlled trials of Tiaogan formula in the treatment of coronary heart disease. The primary outcome measures will be mortality, acute cardiovascular events, total efficacy rate, and improvement of angina symptoms. The secondary outcome measures will be electrocardiogram, levels of blood lipid, and adverse events. RevMan 5.4 software Cochrane Collaboration (London, United Kingdom) will be applied for data synthesis, sensitivity analysis, subgroup analysis, and risk of bias assessment. A funnel plot will be developed to evaluate reporting bias and Egger tests will be used to assess funnel plot symmetries. We will use the Grading of Recommendations Assessment, Development and Evaluation system to assess the quality of evidence. RESULTS: This study will provide a systematic review of Tiaogan formula in the treatment of CHD. CONCLUSION: This study will provide a high-quality synthesis of the effects and safety of Tiaogan formula in the treatment of CHD patients.

The coronary sinus reducer (CSR) has been introduced as therapy for patients with refractory angina with no other treatment options. Aim of this study is to investigate the efficacy of the CSR in patients with refractory angina and presence of coronary chronic total occlusions (CTO). In this multicentre, international retrospective study, patients undergoing CSR implantation were screened and divided in 2 groups according to the presence/absence of CTO lesions. Baseline and clinical characteristics were analyzed in the 2 groups. Primary-outcome consisted of the variation in Canadian Cardiovascular Society (CCS) class at 6-month follow-up. Between January 2014 and December 2018, 205 patients with refractory angina were consecutively treated with the study device in the participating centers, 103 (50.2%) of which had a CTO lesion at coronary angiogram and formed the CTO-group. Baseline characteristics of the study population were well balanced between the 2 groups. CSR was successfully implanted in all cases. Baseline CCS class was 3 ± 0.5 in the CTO-group versus 3.1 ± 0.6 in the non-CTO group (pâ¯=â¯0.45), and improved at follow-up to 1.6 ± 0.9 versus 2 ± 1.1 respectively (p <0.01), with a significantly higher improvement in CCS class in the CTO-group (1.4 ± 0.9 vs 1.1 ± 1 respectively, pâ¯=â¯0.01). Any improvement in CCS class was registered in 79 (80.6%) CTO-patients, while a significantly lower percentage (65 patients, 66.3%) of the non-CTO patients reported benefits in CCS class (pâ¯=â¯0.03). In conclusions, patients suffering from refractory angina with non-revascularized CTO lesions have a better response to CSR implantation than patients without CTOs. CSR implantation should be considered a valid complementary therapy to CTO-PCI in these patients.

BACKGROUND: Patients with refractory angina pectoris experience recurrent symptoms that limit their functional capacity, including psychological distress and impaired health-related quality of life (HRQoL), despite optimized medical therapy. Enhanced external counterpulsation (EECP) is an evidence-based alternative noninvasive treatment. Although physical well-being and mental well-being are equally important components of health, few studies have investigated the psychological effects of EECP in patients with refractory angina pectoris. OBJECTIVE: The aim of this study was to evaluate the effects of EECP treatment in patients with refractory angina pectoris regarding medication profile, physical capacity, cardiac anxiety, and HRQoL. METHODS: This quasi-experimental study with 1-group pretest-posttest design includes a 6-month follow-up of 50 patients (men, n = 37; mean age, 65.8 years) who had undergone 1 EECP course. The following pretreatment and posttreatment data were collected: medication use, 6-minute walk test results, functional class according to the Canadian Cardiovascular Society, and self-reported (ie, questionnaire data) cardiac anxiety and HRQoL. In addition, the questionnaires were also completed at a 6-month follow-up. RESULTS: After EECP treatment, patients used significantly less nitrates (P < .001), walking distance increased on average by 46 m (P < .001), and Canadian Cardiovascular Society class improved (P < .001). In addition, all but 1 subscale of cardiac anxiety and all HRQoL components improved significantly (P < .05). The positive effects for cardiac anxiety and HRQoL were maintained at the 6-month follow-up. CONCLUSIONS: Enhanced external counterpulsation treatment resulted in reduced symptom burden, improved physical capacity, and less cardiac anxiety, leading to increased physical activity and enhanced life satisfaction for patients with refractory angina pectoris. Enhanced external counterpulsation treatment should be considered to improve the life situation for these patients.

OBJECTIVE: To assess the clinical effectiveness and safety of modified 'Huoxue Shugan' (HXSG) formulas used as Chinese herbal medicine in treating patients with coronary heart disease (CHD) and depression. METHODS: A systematic literature search of articles up to March 2018 will be performed in the following electronic databases: PubMed, Embase, the Cochrane Library, China National Knowledge Infrastructure, Chinese Scientific Journals Database, Chinese Biomedical Database, Chinese Biomedical Literature Service System and Wanfang Database. Inclusion criteria are as follows: randomised controlled trials of modified HXSG formulas in patients with CHD and depression. The primary outcome measures will be CHD-related clinical evaluation (frequency of acute angina, severity of angina pectoris, ECG changes, dose of nitroglycerin) and the scores or amount of reduction in scales measuring depression (ie, the Hamilton Depression Scale or other widely used depression scales). The safety outcome measures will be adverse events, liver and kidney function. RevMan V.5.3 software will be used for data synthesis, sensitivity analyses, subgroup analyses and risk of bias assessment. A funnel plot will be developed to evaluate reporting bias. Stata V.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. ETHICS AND DISSEMINATION: This systematic review does not require ethics approval and will be submitted to a peer-reviewed journal. PROSPERO REGISTRATION NUMBER: CRD42018089641.

A retrospective further analysis of the ACTION database evaluated the relationship between cardiovascular outcomes and the "quality" of the control of blood pressure (BP). The study population (n = 6287) comprised those patients with four BP measurements during year 1 subdivided according to the proportion of visits in which BP was controlled in relation to two BP targets: < 140/90mmHg and < 130/80 mmHg. Differences between the BP control groups for the major prespecified ACTION outcomes were investigated with Cox proportional hazards models. For all the prespecified cardiovascular endpoints the incidence declined as the proportion of visits with BP control increased. The greatest differences in outcomes between the different BP control groups were observed for the risk of stroke but were still apparent for all the other endpoints. For example, the risks for the primary outcome [hazard ratio (HR) 0.78; 95% confidence interval (CI) 0.67 to 0.90] were significantly less in the group with >_75% of visits with BP control than in the group with < 25% of visits with BP control. There were no significant treatment-related differences. Retrospective analyses are not definitive but these results highlight the importance of the attainment of BP control targets and the consistency of BP control during long-term follow-up.

This retrospective further analysis of the ACTION database evaluated the relationships between baseline blood pressure (BP), on-treatment BP (after 6 weeks) and subsequent cardiovascular outcomes. Analyses were performed using multivariate Cox proportional hazard models. Statistically significant (p < 0.001) and consistent patterns were noted between the risk of major cardiovascular endpoints and both baseline SBP and on-treatment SBP. The lowest risk of debilitating stroke was apparent in those patients with baseline SBP < 120mmHg, with a hazard ratio in this lowest BP group of 0.45 (95% confidence interval 0.28, 0.72), compared to the referent highest BP group (SBP < 150mmHg). Adjusting the model for treatment (nifedipine or placebo) did not modify the conclusions in any statistical or clinically meaningful way. Corresponding and similar results were obtained for pulse pressure but diastolic blood pressure (DBP) was not a consistently useful predictor of outcome. These data confirm the predictive importance of on-treatment SBP (but not DBP) and contribute to the debate about treatment-related BP targets. In this analysis, treatment with nifedipine gastrointestinal therapeutic system in high-risk patients with coronary artery disease was not associated with any increase in cardiovascular risk, even with baseline SBP5120mmHg.

Objective There are no objective methods for evaluating the severity of vasospasms in patients with refractory coronary spastic angina (R-CSA) under adequate medical therapy. We examined whether spasm provocation tests performed under adequate medication are useful for evaluating the severity of disease in R-CSA patients on emergency admission. Methods and Results We performed spasm provocation tests before and after the administration of medical therapy in eight R-CSA patients, including one ventricular fibrillation survivor (VF-S) and seven patients with unstable angina (UAP) on emergency readmission. We also performed these tests only after medical therapy on urgent admission in four R-CSA patients, including two patients with UAP, one patient with VF-S and one patient with acute coronary syndrome. All 12 R-CSA patients had been medicated with ≥ 2 vasodilator drugs. Positive coronary spasms were defined as >99% transient narrowing. The coronary artery spasms disappeared in three patients under medication, and mitigation of vasospasticity was observed in three patients. In these six cases we continued the same medications. Meanwhile in two patients, we recommended a consultation for psychosomatic medicine. In contrast, the remaining six R-CSA patients exhibited higher levels of vasospasticity, irrespective of the administration of aggressive medical therapy, in which the doses of vasoactive drugs were increased in order to suppress coronary artery spasms. Conclusion In some R-CSA patients on emergency admission, performing spasm provocation tests under medical therapy is useful for determining the subsequent treatment strategy. Therefore, this test may become a new tool in the treatment of R-CSA.

Uncontrolled usage of herbal medications may cause problems that can lead to serious complications, including death. Panax is thought to have hypocholesterolemic, anticarcinogenic, antiinflammatory, and antimicrobial effects via its saponin ingredient and positive inotropic effects via its panax ginseng effect. However, clinical studies have shown that it can increase the low-density lipoprotein (LDL) levels secondary to its hypocholesterolemic effect, have a hypertensive effect in chronic users via ginseng abuse syndrome, and also have hypotensive effects. Here, we present a case with typical angina pectoris in which coronary angiography was suggested but refused. The male patient initiated panax therapy and presented to our emergency department with diffuse anterior myocardial infarction and cardiogenic shock, and was discharged after appropriate therapy.

We report the case of a woman, aged 53 years, admitted for the assessment of angina; her history revealed 3 unexplained miscarriages, all in the first trimester of pregnancy. Based on clinical manifestations and complementary examinations, the patient was diagnosed with stable angina class functional II, according to The Canadian Cardiovascular Society Classification. The assessment of the risk factors shows a moderate hyperhomocysteinemia, due to methylenetetrahydrofolate reductase polymorphism (MTHFR C677T), abdominal obesity and post-menopausal status. We interpreted hyperhomocysteinemia as the pathologic background explaining both cardiovascular and obstetrical conditions in our case. The patient started the combined therapy with folic acid, vitamin B6 and B12 along with the classical treatment for angina, and, 2 months later, homocysteinemia decreased by 28.6% and the clinical condition improved. There are still controversies regarding the role of homocysteine and its genetic determinant MTHFR C677T polymorphism in different pathologic conditions, including the homocysteine paradox: although effective and inexpensive for hyperhomocysteinemia lowering, the vitamins supplementation has not been proved to reduce significantly the recurrence of cardiovascular events. These interrelations are complex and future studies are required to improve the therapeutical strategy in these cases.

BACKGROUND: Acupuncture (AP) might be indicated in emergency medicine. This case series was performed to demonstrate the practicability and possible effects of AP in emergency medical services (EMS) as a basis for randomized controlled trials (RCT). SUBJECTS AND METHODS: A total of 60 patients (average age 55.4±23.0 years, 57% female) treated by the EMS received AP if applicable. Main outcome parameter was to rate the symptom alleviating effect of acupuncture treatment on a 4-point scale or by VAS. RESULTS: Of the 60 patients 35 (58%) reported considerable improvement, 15 patients (25%) reported complete relief and 10 patients (17%) reported no changes in the cardinal symptom. The predominant symptoms alleviated by AP were nausea (n=31) and vomiting (n=21). Pericardium 3 and 6 (27%) and Spleen 6 and 9 were the most commonly used AP points. CONCLUSION: This case series demonstrates that AP can alleviate certain symptoms in emergency patients. The results of the study provide data as a basis to perform clinical controlled trials on the effectiveness of AP in emergency medicine.

OBJECTIVE: To evaluate the safety and efficacy of Xiongshao Capsule (XS), consisting of Chuangxiongol and paeoniflorin, in preventing restenosis after percutaneous coronary intervention (PCI) in senile coronary heart disease (CHD) patients. METHODS: A multi-center, randomized, double-blind, placebo-controlled trial was conducted. A total of 335 CHD patients were randomly assigned to treatment with oral administration of XS, or a placebo for 6 months after successful PCI. A clinical follow-up was performed at 1, 3 and 6 months after PCI and an angiographic follow-up was scheduled at 6 months. The primary endpoint was angiographic restenosis defined as a luminal stenosis ≥ 50% in follow-up. The secondary endpoints were combined incidence of death, target lesion nonfatal myocardial infarction, repeat target-vessel angioplasty, and coronary artery bypass graft surgery (CABG). The follow-up for the above clinical endpoint events was continued to 1 year after PCI. RESULTS: The subgroup analysis of 152 senile patients (68 cases angiographic follow-up) showed that the restenosis rates tended to reduce in the XS group as compared with that in the placebo group (24.32% vs. 38.71%, P > 0.05), and the minimum lumen diameter (MLD) significantly increased in the follow-up (2.15 ± 0.84 for XS vs. 1.73 ± 0.91 for placebo, P < 0.05). The incidence of recurrent angina at 3 and 6 months after PCI was also significantly reduced in the XS group (4.11% and 12.33%) as compared with those in the placebo group (17.72% and 43.04%), but there was no significant difference in the combined incidence of clinical outcomes (6.85% in the XS group vs. 11.39% in the placebo group, P > 0.05). No significant adverse reactions occurred within the 6-month follow-up period in the XS group. CONCLUSION: Administration of XS in addition to standardized Western medication for 6 months is demonstrated to be safe and effective in reducing post-PCI recurrent angina and inhibiting luminal restenosis after PCI in senile CHD patients.

INTRODUCTION: Spinal cord stimulation (SCS) is the most commonly used implantable neurostimulation modality for management of pain syndromes. We present a patient with history of right facial pain successfully treated for refractory angina with SCS and had coincident near resolution of facial pain. CASE DESCRIPTION: A 45 year old male with documented coronary vasospasm presented for consideration of SCS for refractory angina. He underwent successful implantation with significant improvement in his intractable chest pain. Additionally, during trial and post-implantation, the patient described almost complete resolution of his chronic facial pain. Prior to implantation, the facial pain had been thoroughly evaluated without a discernible cause. He had been symptomatically treated for atypical facial pain (AFP) with gabapentin. Post-implantation, the patient was able to discontinue gabapentin and described near complete resolution of his AFP. DISCUSSION: SCS is one of the most promising treatment options for refractory angina. Numerous randomized, controlled trials have demonstrated efficacy in increasing exercise duration and time to angina, decreasing number of angina attacks, sublingual nitrate consumption, and number of ischemic episodes. Reductions in pain, sympathetic tone, and myocardial oxygen demand as well as improvement in coronary microcirculatory blood flow have all been proposed as beneficial outcomes of stimulation. AFP is a poorly understood condition, often without etiology, and most commonly treated symptomatically. The resolution of our patient's AFP is secondary to unclear mechanism(s). We propose SCS may have altered central processing or spinal trigeminal nucleus fibers; additionally, the pain may have been sympathetically mediated and altered by SCS.

OBJECTIVE: A novel antithrombotic agent, lumbrokinase, was evaluated in this pilot study for its efficacy in the treatment of symptomatic stable angina. DESIGN: This was a single-armed cohort study. SETTINGS: The study was conducted at the National Cardiovascular Center, Harapan Kita, Jakarta, Indonesia. SUBJECTS: The study comprised 10 patients who had coronary artery disease and stable angina and who consented to the trial. INTERVENTION: Patients were treated with oral lumbrokinase for 30 consecutive days in addition to their standard medical therapy. OUTCOME MEASURES: Stress technetium-99m sestamibi myocardial perfusion imaging (MPI) was performed before and at the conclusion of the active treatment period. The degree and extent of inducible ischemia observed on the myocardial perfusion images were evaluated using the previously validated semiquantitative indices (Summed Stress Score and Summed Difference Score). RESULTS: Following active treatment, the mean Summed Stress Score and Summed Difference Score deceased by 39% and 37%, respectively. The anginal symptom was ameliorated in 6 of 10 patients. No adverse reaction including major or minor bleeding was observed. CONCLUSIONS: This paper represents the first description of the use of oral lumbrokinase in the treatment of chronic coronary artery disease with objective assessment using MPI. Oral lumbrokinase improves regional myocardial perfusion in patients with stable angina.

BACKGROUND: The aim of this paper was undertake a systematic review and meta-analysis of the use of spinal cord stimulation (SCS) in the management of refractory angina. METHODS: We searched a number of electronic databases including Medline, Embase and Cochrane Library up to February 2008 to identify randomised controlled trials (RCTs) reporting exercise capacity, ischemic burden, functional class, quality of life, usage of anti-anginal medication, costs and adverse events including mortality. Results were reported both descriptively for each study and using random effects meta-analysis. Given the variety in outcomes reported, some outcome results were pooled as standardised mean differences (SMD) and reported in standard deviation units. RESULTS: Seven RCTs were identified in a total of 270 refractory angina patients. The outcomes of SCS were found to be similar when directly compared to coronary artery bypass grafting (CABG) and percutaneous myocardial laser revascularisation (PMR). Compared to a 'no stimulation' control, there was some evidence of improvement in all outcomes following SCS implantation with significant gains observed in pooled exercise capacity (SMD: 0.76, 0.07 to 1.46, p = 0.03) and health-related quality of life (SMD: 0.83, 95% CI: 0.32 to 1.34, p = 0.001). Trials were small and were judged to range considerably in their quality. The healthcare costs of SCS appeared to be lower than CABG at 2-years follow up. CONCLUSION: SCS appears to be an effective and safe treatment option in the management of refractory angina patients and of similar efficacy and safety to PMR, a potential alternative treatment. Further high quality RCT and cost effectiveness evidence is needed before SCS can be accepted as a routine treatment for refractory angina.

BACKGROUND AND AIM: Calcium channel blockers (CCBs) have been reported to reduce the incidence of stroke in hypertensive patients. CCBs are also commonly used to treat patients with angina pectoris (AP). However, there are very few reports on their effects on cardiovascular events, including stroke and end-stage renal disease (ESRD), in patients with AP. This study was designed to assess the differences among CCBs regarding the occurrence of cardiovascular events in patients with AP. METHODS: Clinical records of 226 patients with AP who had received treatment with CCBs in hospital from January 1, 1993 to December 31, 2006 were reviwed. The influence of patient characteristics and medication on the occurrence of cardiovascular events was evaluated (median follow-up period: 4.4 years). Of these 226 patients, 155 were treated with benldipine (CAS 91599-74-5), 36 with diltiazem (CAS 33286-22-5), and 35 were treated with nifedipine (CAS 21629-25-4). RESULTS: Cox proportional hazard regression analysis showed that benidipine was the only CCB that significantly reduced the occurrence of cardiovascular events (HR = 0.39, p < 0.05). Benidipine treatment was associated with higher cardiovascular- and cardiac event-free rates than diltiazem treatment, and higher stroke- and ESRD-free rates than nifedipine. CONCLUSION: This study demonstrated that benidipine prevents the occurrence of cardiovascular events in patients with AP, suggesting that benidipine contributes to a favorable long-term prognosis of such patients.

This study examined the meaning of cardiac pain for chronic stable angina (CSA) patients who participated in a standardized angina psychoeducation program. The patients documented what angina meant to them at sessions 1 and 6 of a 6-week standardized psychoeducation program aimed at enhancing CSA self-management. At session 1, angina was described as a major negative life change characterized by fear, frustration, limitations, and anger. At session 6, angina signified a broad and ongoing pain problem requiring continual self-management in order to maximize quality of life. The findings suggest that the perceived meaning of angina as a burdensome and debilitating life change shifts, during psychoeducation, to one of angina as a broad pain problem requiring ongoing self-management in order to preserve life goals and functioning. How such perceptual shifts in the meaning of cardiac pain might contribute to the overall effectiveness of psychoedcuation warrants further investigation.

Ivabradine is the first selective and specific inhibitor of the I(f) current (the cardiac pacemaker 'funny' current), and provides pure heart rate reduction without altering myocardial contractility, the cardiac conduction system or coronary vascular resistance. Clinical proof of the antianginal efficacy and tolerability of ivabradine comes from the largest clinical development programme that has ever been performed in stable angina, involving more than 5000 patients. Ivabradine was shown to be as effective as well-established reference antianginal drugs, such as beta-blockers and calcium antagonists. It is well tolerated and is free of the most commonly observed side effects of currently prescribed antianginal drugs. It offers clear therapeutic benefits for a whole range of patients with stable angina, including those with contraindications or intolerance to beta-blockers.
