This study will examine the health-related quality of life in patients being treated for chronic heart disease.

Patients 18 years or older with chronic ischemic heart disease and left ventricular dysfunction enrolled in protocols in the National Heart Lung and Blood Institute's Cardiology Branch may participate in this study.

Participants will complete five questionnaires at 3 separate times during the study-once during hospitalization at the NIH Clinical Center and again at home 6 months and 1 year later. The questionnaires, described below, require a total of about 30 minutes to complete.

1. Demographic Information Sheet -General information such as age, marital status, employment, education, and history of cardiac medical procedures.
2. General Health Survey -Patient's self-assessment, on a rating scale, of physical and emotional well being. Questions are related to the ability to perform work and daily living activities, mood and state of mind, limitations on social activities, energy level, pain level, general quality of life, etc.
3. Heart Disease Survey - Patient's self-assessment, on a rating scale, of the level of physical, social, emotional and functional well being related to his or her heart condition. Questions concern fatigue level, emotional outlook, social well being, etc.
4. Angina Survey - Information on the frequency of chest pain, chest tightness, or angina.
5. Symptom Distress Survey - Patient's ranking of the degree of symptom distress from chest discomfort, difficulty breathing, heart rate irregularities, wheezing and coughing.

All information provided in the questionnaires will be kept confidential. Upon request, patients will be sent a summary of the study results when the study is completed.

A majority of the research in patients with chronic ischemic heart disease and left ventricular dysfunction deals with increasing patient survival rates and years. Very little research has focused on patients' perceptions of living with this chronic debilitating disease. The purpose of this naturalistic, prospective study is to assess the Health Related Quality of Life (HRQOL), anginal symptoms and symptom distress experienced by patients with chronic ischemic heart disease and left ventricular dysfunction. The relationship between underlying cardiac condition, anginal symptoms, symptom distress and HRQOL will be examined. The trend in HRQOL across time versus treatment group will be evaluated. The question, does HRQOL, anginal frequency and symptom distress at baseline predict mortality and cardiac related hospitalization during the year following assessment will also be addressed.

Patients who are enrolled in protocols in the Cardiology Branch of the National Heart Lung and Blood Institute (NHLBI) and diagnosed with chronic ischemic heart disease and left ventricular dysfunction will be asked to participate in this HRQOL study. Patients will complete measures of HRQOL (Medical Outcomes Short Form 36 Survey; Minnesota Living with Heart Failure Questionnaire) and symptom measures (anginal frequency subscale of the Seattle Angina Questionnaire; cardiopulmonary subscale of the Heart Transplant Symptom Checklist). Underlying cardiac condition will be assessed using exercise thallium imaging parameters (METS and perfusion defects) and positron emission tomography (PET) imaging parameter (viability). A sample size of 90 subjects is desired for this study. Data will be analyzed using multivariate statistics. It is expected that this study will provide new information regarding how patients with ischemic heart disease and left ventricular function feel their chronic illness and its corresponding treatment(s) affects their HRQOL.
