Abstract

Cardiovascular disease (CVD) is a major cause of disability and premature death throughout the world. In some individuals this can present as stable angina or effort angina and later it may progress as unstable angina, acute coronary syndrome (ACS) or myocardial infarction (MI). In some other individuals it may present directly as acute coronary syndrome or MI. Patients who present with symptoms suggestive of effort angina are advised to undergo stress test to confirm effort inducible ischemia, to test the effort tolerance, to test at what level of exercise and at what level of heart rate (HR) the changes appear on the stress ECG or the person develops symptoms of angina. After this initial assessment, patient will be put on medications and sent home. Patient is called to the hospital for follow up at certain intervals. During one of the visits the stress ECG will be repeated to assess the progression of angina and also to assess the efficacy of treatment. Depending on this result further course of action will be decided. In this paper, we propose a clinical decision support system and method for assessing the progression of angina using smart watch and associated mobile app. This method will reduce the frequent visit to the hospital for assessment of progression of angina.

HOME MONITORING OF ANGINA PATIENTS USING SMART WATCH

Abstract— Cardiovascular disease (CVD) is a major cause of disability and premature death throughout the world. In some individuals this can present as stable angina or effort angina and later it may progress as unstable angina, acute coronary syndrome (ACS) or myocardial infarction (MI). In some other individuals it may present directly as acute coronary syndrome or MI. Patients who present with symptoms suggestive of effort angina are advised to undergo stress test to confirm effort inducible ischemia, to test the effort tolerance, to test at what level of exercise and at what level of heart rate (HR) the changes appear on the stress ECG or the person develops symptoms of angina. After this initial assessment, patient will be put on medications and sent home. Patient is called to the hospital for follow up at certain intervals. During one of the visits the stress ECG will be repeated to assess the progression of angina and also to assess the efficacy of treatment. Depending on this result further course of action will be decided.

In this paper, we propose a clinical decision support system and method for assessing the progression of angina using smart watch and associated mobile app. This method will reduce the frequent visit to the hospital for assessment of progression of angina.

I. INTRODUCTION

Stable angina is a clinical syndrome characterized by discomfort in the chest, jaw, shoulder, back, or arms, typically elicited by exertion or emotional stress and relieved by rest or nitro-glycerine. Less typically, discomfort may occur in the epigastric area. It is usual to confine the term to the cases in which the syndrome can be attributed to myocardial ischemia, although essentially similar symptoms can be caused by disorders of the oesophagus, lungs, or chest wall. Although the most common cause of myocardial ischemia is atherosclerotic CAD, Stable angina pectoris is common and sometimes disabling disorder (1). IHD remains a major public health problem nationally and internationally. It is estimated that 1 in 3 adults in the United States (about 81 million) has some form of cardiovascular disease, including >17 million with coronary heart disease and nearly 10 million with angina pectoris. In approximately 50% of patients, angina pectoris is the initial

manifestation of IHD. The incidence of angina rises continuously with age in women, whereas the incidence of angina in men peaks between 55 and 65 years of age before declining. Despite angina’s clinical importance and high frequency, modern, population-based data are quite limited, and these figures likely underestimate the true prevalence of angina (2). Patients with chest pain should undergo a thorough history and physical examination to determine the probabilit...
