Failed ISCHEMIA Trial or Failed Ischemia Testing?

The results of the ISCHEMIA (International Study of Comparative Health Effectiveness With Medical and Invasive Approach) trial were presented at the American Heart Association Scientific Sessions in November, 2019 in Philadelphia, Pennsylvania, and recently published on March 30, 2020 in the New England Journal of Medicine. After an average follow-up of 3.5 years, invasive therapy did not reduce the major adverse cardiac event (MACE) rate compared with optimal medical therapy (OMT) in patients with stable ischemic heart disease. However, the ISCHEMIA trial results might stem from the revascularization of inappropriate vessels and from the lack of a lesion-specific ischemia detection algorithm to guide revascularization instead of conventional stress testing. The utilization of an initial computed tomography (CT) angiogram with or without fractional flow reserve CT could have produced better revascularization results

Designing a business Plan for a European-Nepalese Fusion Restaurant in Nepal

The author draws up a business plan in this thesis on the basis of research, personal experi-ences and understanding with the intention of implementing it in real life. The main objec-tive of this thesis is to generate a business plan for authors own restaurant. The author intends to establish a European-Nepalese fusion restaurant in Nepal which will serve break-fast, lunch and dinner alongside non-alcoholic beverages. The theoretical framework of the thesis theories, such as food culture in Nepal and Europe, where European, Nepalese food culture and fusion food trends are briefly discussed. It helps the author to deeply understand both food cultures and the potential of establishing a fusion food restaurant in Nepal. Entrepreneurship provides an idea on how to start and op-erate the business, factors affecting entrepreneurship as well as entrepreneurship opportu-nities in Nepal. The theory section also includes a business plan where the types of a busi-ness plan and its advantages, financial planning in business plan are included. It provides some knowledge about the process of building a business plan for a restaurant and factors to focus on. The business plan teaches the importance of creating a business plan for any company and how it is prepared in relation with the business canvas model. The business model canvas illustrates the key factors of the company which are the most essential factors to start and operate any business. The research methods used for the development of this thesis are online interview and net-scouting. The online interview was conducted with the owner and manager of Sri Sai palace restaurant and bar located in Jhapa, Nepal, with the concept of obtaining genereal information about planning and opening a new restaurant in Nepal. Similarly, net-scouting was done obout three Nepalese restaurants located in the capital region of Nepal inorder to have an idea about the ideal location, products and services and customers. The outcome of this thesis helped the author to have a better understanding of creating an effective business plan, how to write it and eventually apply it in the real market. The information collected during the thesis process helped the author to have a better understanding of the factors needed to operate a restaurant. The interview provided specific information to establish and operate a restaurant in Nepal. The results of net-scouting helped the author to focus on the specif areas to ensure the success of the business

Implications of serial coronary computed tomography angiography in the evaluation of coronary plaque progression.

Purpose of reviewThe purpose is to review the use of coronary computed tomography (CT) angiography to assess coronary plaque burden/progression and to discuss about recent clinical trials that have utilized this imaging modality to study the effect of new pharmacotherapies on plaque burden/progression.Recent findingsThere are numerous clinical trials that have utilized coronary CT angiography to demonstrate the potential benefits of statins, apixaban, rivaroxaban, aged garlic extract, biologic agents, and omega-3 fatty acids to reduce coronary plaque progression. Coronary CT angiography can identify high-risk plaques and can also quantify total plaque burden, both of which are independent risk factors to predict major adverse cardiac events.SummaryCoronary heart disease remains one of the leading cause of mortality in the world. Utilizing coronary CT angiography, it is possible to identify rupture-prone plaques and also to quantify the total plaque burden. New pharmacotherapies that have the potential to reduce plaque progression have been used in clinical trials and these trials have utilized coronary CT angiography to track coronary atheroma progression. In future, we will see frequent utilization of coronary CT angiography to track coronary atheroma

Coronary Computed Tomography Angiography for Evaluation of Chest Pain in the Emergency Department.

Coronary computed tomography angiography has emerged as an important diagnostic modality for evaluation of acute chest pain in the emergency department for patients at low to intermediate risk for acute coronary syndromes. Several clinical trials have shown excellent negative predictive value of coronary computed tomography angiography to detect obstructive coronary artery disease. Cardiac biomarkers such as troponins and creatine kinase MB, along with history, electrocardiogram, age, risk factors, troponin score, and Thrombolysis in Myocardial Infarction score should be used in conjunction with coronary computed tomography angiography for safe and rapid discharge of patients from the emergency department. Coronary computed tomography angiography along with high-sensitivity troponin assays could be effective for rapid evaluation of acute chest pain in the emergency department, but high-sensitivity troponins are not always available. Emergency department physicians are not quite comfortable making clinical decisions, especially if the coronary stenosis is in the range of 50% to 70%. In these cases, further evaluation with functional testing, such as nuclear stress testing or stress echocardiogram, is a common approach in many centers; however, newer methods such as fractional flow reserve computed tomography could be safely incorporated in coronary computed tomography angiography to help with clinical decision-making in these scenarios

Utilizing coronary artery calcium to guide statin use.

Cardiovascular disease (CVD) is the leading cause of death worldwide, and accounts for over 30% of annual global fatality. Coronary artery calcium (CAC) screening, a highly distinct marker of coronary atherosclerosis, serves as an important arbitrator of atherosclerotic cardiovascular disease (ASCVD). Particularly in asymptomatic individuals, CAC testing offers a model for initiating or prolonging preventative statin therapies and subsequently up- or down-risking of patients. Though recent 2018 ACC/AHA Guidelines on Blood Cholesterol recommend CAC as an arbitrator of statin use, it remains uncertain whether these recommendations have been universally followed. Thus, we present a thorough discussion about CAC as an important determinator of ASCVD risk. In this regard we highlight the key points behind coronary artery calcium scoring, as a critical platform for stratifying risk and guiding future preventative treatments. This review paper supplies a background for the 2018 Cholesterol Guidelines: the rationalization behind CAC as a crucial arbitrator of cardiovascular risk. This paper will first (1) outline the role of CAC in reclassifying ASCVD risk. Next, it will (2) discuss studies that illustrate CAC's markedly novel reduction in the number needed to treat (NNT) to ameliorate one major cardiac event. Being years removed from 2018 Guidelines provides this paper the lens to (3) elucidate upcoming value-based advantages, cost effectiveness, and patient adherence brought by CAC. Last, this paper will also (4) extend the utility of CAC beyond that of the general population, and (5) discuss pertinent limitations brought by CAC score. By summarizing the framework behind recent cholesterol guidelines for ASCVD risk assessment, this review will address the debate of use of CAC for both the clinical setting and preventative therapy applications
