Ranolazine for stable angina pectoris.

Stable angina pectoris is a chronic medical condition with significant impact on mortality and quality of life; it can be macrovascular or microvascular in origin. Ranolazine is a second-line anti-anginal drug approved for use in people with stable angina. However, the effects of ranolazine for people with angina are considered to be modest, with uncertain clinical relevance.


The prevalence and management of angina among patients with chronic coronary artery disease across US outpatient cardiology practices: insights from the Angina Prevalence and Provider Evaluation of Angina Relief (APPEAR) study.

Although eliminating angina is a primary goal in treating patients with chronic coronary artery disease (CAD), few contemporary data quantify prevalence and severity of angina across US cardiology practices. The authors hypothesized that angina among outpatients with CAD managed by US cardiologists is low and its prevalence varies by site. Among 25 US outpatient cardiology clinics enrolled in the American College of Cardiology Practice Innovation and Clinical Excellence (PINNACLE) registry, we prospectively...

Correlation of heart rate variability with SYNTAX II on chronic angina.

The heart rate variability (HRV) is a prognostic value of cardiovascular risk. It is unknown the correlation between HRV and coronary severity on patients with chronic angina. The objective was to determine the correlation between HRV and the SYNTAX II score in chronic angina.


Sex Differences in Cardiac Medication Use Post-Catheterization in Patients Undergoing Coronary Angiography for Stable Angina with Nonobstructive Coronary Artery Disease.

Treatment of patients with stable angina and nonobstructive coronary artery disease (CAD) has not been well characterized. We comparatively evaluated medication use in males and females with stable angina with no CAD, nonobstructive CAD, and obstructive CAD.

Typical angina is associated with greater coronary endothelial dysfunction but not abnormal vasodilatory reserve.

Typical angina (TA) is defined as substernal chest pain precipitated by physical exertion or emotional stress and relieved with rest or nitroglycerin. Women and elderly patients are usually have atypical symptoms both at rest and during stress, often in the setting of nonobstructive coronary artery disease (CAD).

Importance of compensatory heart rate increase during myocardial ischemia to preserve appropriate oxygen kinetics.

Myocardial ischemia induces cardiac dysfunction, resulting in insufficient oxygen supply to peripheral tissues and mismatched energy production during exercise. To relieve the insufficient oxygen supply, heart rate (HR) response is augmented; however, beta-adrenergic receptor blockers (BB) restrict HR response. Although BB are essential drugs for angina pectoris, the effect of BB on exercise tolerance in patients with angina has not been studied. The aim of this study was to clarify the importance of HR aug...

Inorganic Nitrate in Angina Study: A Randomized Double-Blind Placebo-Controlled Trial.

In this double-blind randomized placebo-controlled crossover trial, we investigated whether oral sodium nitrate, when added to existing background medication, reduces exertional ischemia in patients with angina.

Inferior J waves in patients with vasospastic angina might be a risk factor for ventricular fibrillation.

There is little information about the relationship between J waves and the occurrence of ventricular fibrillation (VF) in patients with vasospastic angina (VSA). The present study aimed to assess the incidence of J waves and the occurrence of VF in patients with VSA.

T786C Mutation in the Endothelial Nitric Oxide Synthase Gene in Patients With Primary Osteonecrosis.

Mutations in the T786C endothelial nitric oxide synthase gene (eNOS) are associated with osteonecrosis and Prinzmetal's angina. Nitric oxide is necessary for bone health and ameliorates Prinzmetal's angina. This study compared mutations of T786C eNOS in 146 patients with primary osteonecrosis, 114 patients with Prinzmetal's angina, and 83 normal control subjects. Patients with osteonecrosis had more mutant eNOS alleles than control subjects (42% vs 22%, respectively; P

Impact of ranolazine on coronary microvascular dysfunction (MICRO) study.

Patients with angina and coronary microvascular dysfunction, without evidence of structural or epicardial coronary disease (Type I CMVD) remain without evidence based treatment options. Previous work has demonstrated that ranolazine can improve angina frequency and stability among patients with Type 1 CMVD; however, the mechanism remains unclear. Therefore, the objective of this pilot project was to assess the impact of ranolazine on Type I CMVD as measured using an invasive tool to measure global resistanc...

An unexpected cause of angina and survived sudden cardiac death.

Angina Recurrence After Coronary Artery Bypass Grafting Caused by the Coronary-Subclavian Steal Syndrome.

We present two cases of surgical treatment of patients with coronary artery steal syndrom and multifocal atherosclerosis, who previously underwent coronary artery bypass grafting using left internal mammary artery. In both cases carotid-subclavian bypass was performed through supraclavicular access using synthetic prosthesis. This method allowed to restore blood flow in the left internal mammary artery, eliminate recurrent angina pectoris, and improve patients quality of life. The article also contains desc...

Angina bullosa hemorrhagica: report of 7 cases and analysis of 199 cases from the literature.

Angina bullosa hemorrhagica (ABH) is a condition characterized by blood blisters in the oral or oropharyngeal mucosa. Typically, the first presentation of ABH is acute, and rupture of the blisters occurs after a few hours or days. Although its etiology is unclear, ABH is assumed to be associated with predisposing factors such as local trauma or chronic use of inhaled steroids. The diagnosis is defined clinically, based on the presentation and evolution of the lesions. The recommended treatment is symptomati...

WITHDRAWN: Trimetazidine for stable angina.

Patients with stable angina not controlled by monotherapy with nitrates, beta blockers, or calcium channel blockers are often treated with combinations of these drugs. There may be adverse effects from, or contraindications to, the use of combinations. In low risk groups, medical treatment appears to be as good an option as percutaneous transluminal coronary angioplasty in terms of averting myocardial infarction, death, or subsequent revascularization. Revascularization procedures are too costly or inaccess...

Microfluidic assay of circulating endothelial cells in coronary artery disease patients with angina pectoris.

Circulating endothelial cells (CECs) are widely reported as a promising biomarker of endothelial damage/dysfunction in coronary artery disease (CAD). The two popular methods of CEC quantification include the use of immunomagnetic beads separation (IB) and flow cytometry analysis (FC); however, they suffer from two main shortcomings that affect their diagnostic and prognostic responses: non-specific bindings of magnetic beads to non-target cells and a high degree of variability in rare cell identification, r...

A rare case of Ludwig's angina after viper bite.

Sequential and urgent coronary artery bypass surgery followed by kidney transplantation in a highly sensitized patient with unstable angina.

Association analyses based on false discovery rate implicate new loci for coronary artery disease.

Genome-wide association studies (GWAS) in coronary artery disease (CAD) had identified 66 loci at 'genome-wide significance' (P < 5 × 10(-8)) at the time of this analysis, but a much larger number of putative loci at a false discovery rate (FDR) of 5% (refs. 1,2,3,4). Here we leverage an interim release of UK Biobank (UKBB) data to evaluate the validity of the FDR approach. We tested a CAD phenotype inclusive of angina (SOFT; ncases = 10,801) as well as a stricter definition without angina (HARD; ncases = ...

Differential proteome profile in ischemic heart disease: Prognostic value in chronic angina versus myocardial infarction. A proof of concept.

The initial clinical manifestation of ischemic heart disease (IHD) i.e. unheralded myocardial infarction (MI) versus chronic angina pectoris (AP) is statistically associated with adverse or mild disease progression respectively in the long-term follow-up. Here, we subjected AP and MI patients to blood proteomic analysis by Surface-Enhanced Laser Desorption/Ionization Time-of-Flight Mass Spectrometry (SELDI-TOF-MS) in order to investigate putative new prognostic biomarkers of IHD manifestation. We found seve...

Hybrid Coronary Revascularization of Minimally Invasive Coronary Artery Bypass Grafting and Percutaneous Coronary Intervention in a Patient with Left Main Coronary Stenosis.

We report a successful case of hybrid coronary revascularization of minimally invasive coronary artery bypass grafting( MICS-CABG) and percutaneous coronary intervention(PCI). The patient was a 78-year-old man with angina pectoris due to left main trunk (LMT) lesion, and had a history of repeated PCI to the left anterior descending artery (LAD) and the left circumflex artery (LCX) for angina pectoris. He presented with a chest pain on effort in June, 2015. A coronary angiogram showed a severe stenosis in th...

Comorbidities of rheumatoid arthritis: Results from the Korean National Health and Nutrition Examination Survey.

This study aimed to evaluate the prevalence of comorbidities in patients with rheumatoid arthritis (RA) compared with the non-RA population. The 2010-2012 Korea National Health and Nutrition Examination Survey (KNHANES), which assesses the general health status of populations in South Korea using interviews and basic health assessment, was analyzed retrospectively. Weighted prevalence and odds ratio (OR) of comorbidities were analyzed in patients with RA compared with the non-RA population. The overall weig...

Efficiency of ranolazine in the patient with microvascular angina, atrial fibrillation and migraine.

Microvascular angina (MVA) is rather a common form of stable ischemic coronary disease (CAD) as that such diagnosis is made in 20-30% of patients who previously underwent coronary angiography. The disease occurs three times more frequently in women than in men irrespective of age. Most of these patients are 45-60 years old. According to available data, the long-term outcome in patients with MVA is comparable with that in general population. MVA characterizes great variability of its course and low response ...

Arginine methylation dysfunction increased risk of acute coronary syndrome in coronary artery disease population: A case-control study.

The plasma levels of asymmetric dimethylarginine (ADMA) had been proved to be an independent cardiovascular risk factor. Few studies involved the entire arginine methylation dysfunction. This study was designed to investigate whether arginine methylation dysfunction is associated with acute coronary syndrome risk in coronary artery disease population.In total 298 patients undergoing coronary angiography because of chest pain with the diagnosis of stable angina pectoris or acute coronary syndrome from Februa...

Tanshinol sustained-release pellets with absorption enhancer: optimization, characterization, pharmacokinetics and pharmacodynamics.

The objective of this study was to develop tanshinol sustained-release pellets (TS-SRPs) for the treatment of angina. Considering the poor intestinal absorption of TS, sodium caprate (SC) was used as an absorption enhancer for bioavailability improvement. Single-pass intestinal perfusion in rats demonstrated that the permeability of TS was remarkably enhanced, when the weight ratio of TS to SC was 1:3. Then, the cores were prepared with TS, SC and MCC at a weight ratio of 1:3:16 via extrusion-spheronization...

A Comprehensive Review of Stress Testing in Hypertrophic Cardiomyopathy: Assessment of Functional Capacity, Identification of Prognostic Indicators, and Detection of Coronary Artery Disease.

Hypertrophic cardiomyopathy is a heterogeneous condition that may present with functional limitation due to dyspnea on exertion, angina, or symptoms of heart failure. Although angina is a common symptom, it is thought to be multifactorial, including abnormal microvasculature and epicardial coronary artery disease. The role of stress testing in the detection of coronary artery disease and its limitations are discussed in this review. Stress testing yields additional information beyond the detection of ischem...
