Project description:Nearly 40% of patients presenting to the catheter laboratory with angina have non-obstructed coronary arteries (ANOCA), an umbrella term that encompasses distinct pathophysiological entities, such as coronary artery spasm. Coronary artery spasm leads to sudden reversible coronary flow attenuation, which clinically manifests as vasospastic angina (VSA). VSA is associated with poor quality of life and an increased risk of major adverse cardiac events. However, the pathophysiological mechanisms underlying this phenomenon are incompletely understood, which has resulted in limited therapeutic options for patients afflicted with this condition. The past decade has seen a surge in new research being conducted in the field of ANOCA and VSA. This review article provides a comprehensive summary of the underlying pathophysiological mechanisms of VSA and the current therapeutic options. We also appraise the current diagnostic approach in patients with suspected VSA.

Project description:Refractory angina (RA) is defined as chest pain caused by coronary ischemia in patients on maximal medical therapy and is not amenable to revascularization despite advanced coronary artery disease (CAD). The long-term prognosis has improved with optimal medical therapy including risk factor modification. Still, patients are left with major impairment in quality of life and have high resource utilization with limited treatment options. We review the novel invasive and noninvasive therapies under investigation for RA.

Project description:Recognition of suspected ischaemia with no obstructive coronary artery disease - termed INOCA - has increased over the past decades, with a key contributor being microvascular angina. Patients with microvascular angina are at higher risk for major adverse cardiac events including MI, stroke, heart failure with preserved ejection fraction and death but to date there are no clear evidence-based guidelines for diagnosis and treatment. Recently, the Coronary Vasomotion Disorders International Study Group proposed standardised criteria for diagnosis of microvascular angina using invasive and non-invasive approaches. The management strategy for remains empirical, largely due to the lack of high-levelevidence- based guidelines and clinical trials. In this review, the authors will illustrate the updated approach to diagnosis of microvascular angina and address evidence-based pharmacological and non-pharmacological treatments for patients with the condition.

Project description:Chronic heart failure (CHF) remains the only cardiovascular disease with an increasing hospitalization burden and an ongoing drain on health care expenditures. The prevalence of CHF increases with advancing life span, with diastolic heart failure predominating in the elderly population. Primary prevention of coronary artery disease and risk factor management via aggressive blood pressure control are central in preventing new occurrences of left ventricular dysfunction. Optimal therapy for CHF involves identification and correction of potentially reversible precipitants, target-dose titration of medical therapy, and management of hospitalizations for decompensation. The etiological phenotype, absolute decrease in left ventricular ejection fraction and a widening of QRS duration on electrocardiography, is commonly used to identify patients at increased risk of progression of heart failure and sudden death who may benefit from prophylactic implantable cardioverter-defibrillator placement with or without cardiac resynchronization therapy. Patients who transition to advanced stages of disease despite optimal traditional medical and device therapy may be candidates for hemodynamically directed approaches such as a left ventricular assist device; in selected cases, listing for cardiac transplant may be warranted.

Project description:Basal cell carcinoma (BCC) is the most common, accounting for 80-90% of skin cancers. It arises from the basal layer of the epidermis and its appendages. A complex interplay of environmental, phenotypic and genetic variables leads to the development of BCC. Literature has documented several clinical subtypes of BCC, the most common of which are nodular, superficial and morpheaform. Expeditious diagnosis and analysis are essential for improving the outcome of BCC. Preventive measures, particularly when implemented in childhood and adolescence, may play a critical role. Due to its low metastatic potential, treatment for BCC mostly focuses on local management. The standard treatment of basal cell carcinoma involved complete removal of the lesion by excision or Mohs surgery. In special circumstances, basal cell carcinoma can be treated with cryosurgery, electrodesiccation and curettage, topical medications and photodynamic therapy. This review aimed to evaluate the contemporary diagnosis and management of basal cell carcinoma.

Project description:Vasospastic angina can sometimes induce acute myocardial infarction in pregnant women, potentially endangering the lives of mother and child. We describe a case of a young woman with suspected vasospastic angina who wished to become pregnant. Vasospasm provocation testing revealed severe vasospasm, and subsequent appropriate management resulted in successful delivery.

Project description:With improvements in survival from coronary artery disease (CAD) and an ageing population, refractory angina (RA) is becoming an increasingly common clinical problem facing clinicians in routine clinical practice. These patients experience chronic symptoms in the context of CAD, characterised by angina-type pain, which is uncontrolled despite optimal pharmacological, interventional and surgical therapy. Although mortality rates are no worse in this cohort, patients experience a significantly impaired quality of life with disproportionately high utilisation of healthcare services. It has been increasingly recognised that the needs of RA patients are multifactorial and best provided by specialist multi-disciplinary units. In this review, we consider the variety of therapies available to clinicians in the management of RA and discuss the promise of novel treatments.

Project description:The treatment of dyslipidemia continues to be a dynamic and controversial topic. Even the most appropriate therapeutic range for lipid levels-including that of triglycerides and low-density lipoprotein cholesterol-remain actively debated. Furthermore, with ever-increasing options and available treatment modalities, the management of dyslipidemia has progressed in both depth and complexity. An understanding of appropriate lipid-lowering therapy remains an essential topic of review for practitioners across medical specialties. The goal of this review is to provide an overview of recent research developments and recommendations for patients with dyslipidemia as a means of better informing the clinical practice of lipid management. By utilizing a guideline-directed approach, we provide a reference point on optimal lipid-lowering therapies across the spectrum of dyslipidemia. Special attention is paid to long-term adherence to lipid-lowering therapies, and the benefits derived from instituting appropriate medications in a structured manner alongside monitoring. Novel therapies and their impact on lipid lowering are discussed in detail, as well as potential avenues for research going forward. The prevention of cardiovascular disease remains paramount, and this review provides a roadmap for instituting appropriate therapies in cardiovascular disease prevention.

Project description:ImportancePulmonary arterial hypertension (PAH) is characterized by severe remodeling of the distal pulmonary arteries, increased pulmonary vascular resistance, and right ventricular dysfunction that promotes heart failure. Once regarded as largely untreatable, evidence-based decision making now guides clinical management of PAH and improves outcomes. However, misconceptions regarding the approach to PAH in the modern era are common and associated with substandard clinical care.ObservationsThe clinical profile of PAH has changed substantially since its original description. Patients are older at diagnosis than previously reported; disease severity appears greater in men compared with women; and patients with PAH in association with connective tissue disease are identified as a particularly high-risk subgroup. Risk stratification scales for PAH are now available at point of care, which inform treatment goals, including a 6-minute walk distance of greater than 440 m, peak volume of oxygen consumption of greater than 15 mL/min/kg, right atrial area of less than 18 cm2, cardiac index of greater than 2.5 L/min/m2, and absent or low symptom burden with routine physical activity. At present, 14 therapies targeting 6 PAH-specific molecular intermediaries are used clinically. Recent landmark trial data have demonstrated the critical importance of initial combination therapy in treatment-naive patients. These findings underscore a global shift in PAH that couples early disease detection with aggressive pharmacotherapy. Indeed, recent longitudinal data from patients receiving combination therapy show that the 3-year survival rate in PAH may be as high as 84% compared with 48% from the original National Institutes of Health registry on idiopathic PAH (1980-1985). Despite these gains, incomplete clinical evaluation and misdiagnosis by referring clinicians is common and associated with inappropriate therapy.Conclusions and relevanceCompared with the original clinical experience, PAH has evolved into a contemporary and treatable disease characterized by improved survival and a high standard for defining therapeutic success. However, underawareness among clinicians regarding the importance of early and accurate PAH diagnosis persists and is a potentially reversible cause of adverse outcome in this disease.

Project description:Microvascular angina (MVA), historically called cardiac syndrome X, refers to angina with nonobstructive coronary artery disease. This female-predominant cardiovascular disorder adds considerable health-related costs due to repeated diagnostic angiography and frequent hospital admissions. Despite the high prevalence of this diagnosis in patients undergoing coronary angiography, it is still a therapeutic challenge for cardiologists. Unlike obstructive coronary artery disease, with multiple evidence-based therapies and management guidelines, little is known regarding the management of MVA. During the last decade, many therapeutic interventions have been suggested for the treatment of MVA. However, there is a lack of summarization tab and update of current knowledge about pharmacologic management of MVA, mostly due to unclear pathophysiology. In this article, we have reviewed the underlying mechanisms of MVA and the outcomes of various medications in patients with this disease. Contrary to vasospastic angina in which normal angiogram is observed as well, nitrates are not effective in the treatment of MVA. Beta-blockers and calcium channel blockers have the strongest evidence of improving the symptoms. Moreover, the use of angiotensin-converting enzyme inhibitors or angiotensin receptor blockers, statins, estrogen, and novel antianginal drugs has had promising outcomes. Investigations are still ongoing for vitamin D, omega-3, incretins, and n-acetyl cysteine, which have resulted in beneficial initial outcomes. We believe that the employment of the available results and results of the future large-scale trials into cardiac care guidelines would help reduce the global cost of cardiac care tremendously.
