6. BRIEF RESUME OF THE INTENDED WORK:
6.1 Need for the study:
The heart requires a balance between oxygen supply and demand in order to function properly. The integrity of the coronary artery is an important determinant of oxygen supply to the heart muscles. Any disorder that reduces the size of lumen of coronary arteries may cause a decrease in blood flow and oxygen delivery to the myocardium which is life threatening condition characterized by the formation of local necrotic areas within the myocardium. Acute Myocardial Infarction usually follows the sudden occlusion of a coronary artery and the abrupt cessation of blood and oxygen flow to the heart muscles. Because the heart muscle must function continuously, blockage of blood to the muscle leads to development of necrotic areas which can be lethal.1
Atherosclerotic plaque and subsequent thrombus formations are the most common causes. It is identified that nearly 95 per cent of the people who developed a fatal cardiovascular diseases had at least one of these major risk factors: high blood pressure, smoking, diabetes beside a poor diet and over weight.5
The clinical manifestations associated with Myocardial Infraction results from ischemia of the heart muscle and the decrease in function and acidosis associated with it. The major clinical manifestation of acute Myocardial Infarction is chest pain which may radiate to the neck, jaw, shoulder, back, or left arm. The pain also may be present in the epigastrium, stimulating indigestion. Acute Myocardial Infarction may also be associated with less common clinical manifestations which include atypical chest pain, back ache, or abdominal pain, nausea, dizziness, unexplained anxiety, weakness or fatigue, palpitation, cold sweat, or paleness, the Blood pressure and pulse rate may be elevated, late the blood pressure may drop, urine out put may be decreased, crackles may be noted in the lungs persisting for several hours to several days.1 & 2
Almost everyday, the news media covers a story on a celebrity who has suffered from or was treated for chest pain heart attack or cardiac arrest. Even on television, it is very common scene some body seeking treatment for an episode of chest pain. 1
In the year 2003, It was estimated that heart attacks are the leading cause of death among both men and women all over the world. Cardiovascular diseases are the world’s leading killer, accounting for 16.7million or 29.2 per cent of the total global deaths.4
In the year 2007, WHO estimated that globally 29 per cent of deaths were due to cardiovascular diseases and among them, 25-28 per cent of deaths were due to Myocardial Infarction.3 And more than one million Americans had a new or recurrent acute coronary syndrome and responsible for more than 250,000 deaths annually.1
In the developing countries like India, Myocardial Infarction is one of the leading cause of deaths. The prevalence of Myocardial Infarction has increased from 40 per 1000 in 1968 to nearly 110 per 1000 in 2001. The prevalence of coronary heart disease in urban population has increased from 3.5 per cent in 1960’s to 9.5 per cent in 1990’s,and in rural areas it has been increased from 2 per cent in 1970’s to 4 per cent in 1990’s. In the year 2005, it was estimated that 30 per cent of deaths in India were due to coronary syndrome. 3
The population based surveys conducted in India shows that there is an increase in the prevalence rate of Ischemic heart disease from 1-4 per cent to 10 per cent. According to the hospital statistics in 1980 Coronary Artery Bypass Grafting (CABG) accounted for less then 10% of all cardiac surgeries. Today, it accounts for more than 60%. Every year 25,000 coronary bypass operations and 12,000 Percutaneous coronary Angioplasties (PTCAs) are carried out. In 1999 a total of 6607 valve replacements were done mostly for RHD and 6750 surgeries for congenital cardiac defects.
In the year 2002, WHO estimated that 60 per cent of the world’s Cardiac Patients will be Indians by the year 2010. The medical NGO in cordination with WHO estimated that nearly 50 per cent of Cardio vascular related diseases in India occur below the age of 70, compared with just 22 per cent in the West. This trend is alarming because of its potential on Indian Economics. 4
It is estimated that cardiovascular diseases in USA Cost $274 billion each year, including the health expenditures and productivity.6
Nursing is built on a body of knowledge discreetly synthesized from physical, biological, and social science and uniquely applied as a humanistic discipline of caring for people wherever they are recognizing the health care needs of patients. Nurses must incorporate scientific knowledge and technical advances into their practice to assist the patients in remaining well and functioning at the maximum level.
Specially in critical care units of hospitals, with the advancing science and technology on par with doctors, the nurses should upgrade their knowledge. They must be able to identify life threatening arrhythmias on the electrocardiogram and to perform emergency resuscitation measures if necessary without the aid of the doctor on standing orders. The nurses specialized in the care of the patients with Myocardial Infarction and experience in cardiac care units have truly become a significant and responsible figure in the total field of health care. She meets the demands of patients and at the same time rehabilitates in such a way that the patient fits in the society.
A descriptive study was conducted to assess the knowledge of sedentary workers regarding Myocardial Infarction at Raichur. The sample size was 150 sedentary workers consisting of both males and females equally. A structured questionnaire was used for collecting the data. The results showed that one sixth of the sedentary workers had high knowledge (16%), nearly two third of the sedentary workers had average knowledge (61.33%), and more than one fifth of the sedentary workers had low knowledge (22.66%). The study concluded by saying that they is a significant relationship between the knowledge of sedentary workers on Myocardial Infarction with regard to selected variables like education, occupation and habits.8
Cardiovascular diseases exert a burden on individual and society which is the single most common cause of death. In the community setting, nurses as health workers have a major role in educating and identifying the risk groups. In ICU’s, the nurses working round the clock have a major responsibility in caring the patients with cardiac disorders in general, Myocardial Infarction in specific, and identifying the complications on monitoring the patients manually and on machines .
Hence, the researcher felt the need to assess the knowledge of staff nurses regarding first 24 hours care of patients with Myocardial Infarction admitted to ICU in selected hospital of Raichur with a view to develop self instruction module
6.2. REVIEW OF LITERATURE:

The results showed that mean score of degree nurses in the following areas were: 38.24 in introduction, 29.73 in procedure, 33.81 in interpretation, 31.52 in identification of cardiovascular disorders. The mean score of diploma nurses were 36.93 in introduction, 41.64 in procedure, 21.76 in interpretation and 19.45 in identification of cardiovascular disorders. The study concluded that the degree staff nurses had more knowledge on electrocardiogram as compared to the diploma staff nurses.13
A descriptive study was conducted to assess the knowledge of risk factors, life habits and personal beliefs of nurses and nursing students about cardiovascular prevention in Italy. A sample of 182 nurses were selected by using random sampling technique in which 98 students attending the last year course in School of Nursing, and 84 nurses working in a cardiovascular department were there. Data were collected by using questionnaire. The results showed that among heritable risk factors, hypertension ranked first in the awareness of both students and nurses. The risk inherent in a family history of Myocardial Infarction was recognized only by 36 per cent of subjects, 15 per cent of staff nurses and 30 per cent of students recognized that 5 to 10 of cigarettes per day are not harmful respectively. The knowledge of upper normal limits for blood pressure, plasma cholesterol and triglycerides was often poor in both the cohorts. The study concluded by saying that majority of the staff nurses and student nurses life style was a credible model for patients. 14
A comparative study was conducted to determine the feasibility and efficiency between the nurse-led clinic and resident-led clinic for stable patient recovery from recent Myocardial Infarction in Alkmaar. Samples of 200 patients were selected and the patients were randomized on transfer from the coronary-care unit to the cardiology ward. Subsequently, these patients were treated by a registered nurse practitioner (n=97) or by a resident (n-103) both of whom were under the direct supervision of the attending cardiologist. Degree of satisfaction was scored by the patients on a 0-10 point scale. The study results reported that no significant differences were found between the groups. However, patients treated by the nurse practitioners expressed a significantly higher score in the satisfaction rates. The study concluded by saying the treatment of stable post Myocardial Infarction patient in nurse-led clinic was found to be feasible and effective with a significantly higher level of patient’s satisfaction. 15
A comparative study was done to know the level of assessment of ischemic chest pain by using visual analogue scale among the nurses and patients. The sample included 10 expert nurses and 100 patients admitted to coronary care unit. The nurses underwent a short programme on pain management. They were allowed to rate the pain as assessed by them separately using the scale. The results showed a strong positive correlation between the patient and nurses rating of pain. 16
An experimental study was conducted to measure perception and behavior regarding patient’s involvement among physicians and nursing staff caring for patients with acute Myocardial Infarction in Sweden. A sample of cardiology staff at 12 Swedish Hospitals were selected by simple random technique. The data was collected by structured questionnaire including 6 scale measuring the staff’s views and behaviors. The results of the study showed that physicians and nurses did not differ significantly in their views of patient’s involvement. 17
