Despite the numerous references on the use of various anesthetic agents and analgesics before the moment described in the previous historical appointment, this event is considered the first anesthesia and the starting point for a new era in the history of medicine. An endless sequence of events leading to the development of surgery, all of its specialties and new anesthesia techniques, begins at the same time as the academic development of a new rapidly advancing medical thing: Anesthesiology [1].

Modern anesthesia no longer refers only to the anecdotal administration of drugs to keep a patient unconscious and immobile during a surgical procedure, nor to the limited contribution to medical care that characterized him during his early years. Its development goes further and now requires specialists in the field, the development of multiple and broad knowledge, as well as the practice of different techniques and skills that necessitate an integrated approach of specialization with the sole purpose of influencing beneficially, through care the outcome of the surgical care provided to the patient [2].

This is the method today, although the basis of our specialty is recognized in the practice of intraoperative anesthesia, which is why things such as anesthesia and specialists in it such as anesthesiologists are still remembered in academic settings. The specialization includes the management during the entire perioperative phase of the patient under a surgical procedure, which provides for the direction of the preoperative patient, assessment and improvement in this phase, and postoperative management, especially in the area of pain management and continuity intraoperative care. These aspects lead to a pronounced decrease in the stay in intensive care. In this way and through the latest advances in technologies and techniques, specialization involves the entire perioperative period, giving rise to a new form of medical practice: perioperative medicine [3-5].

The revolving evolution of the medical and surgical specialties has forced anesthesiology to follow the same path as its counterparts; The diversity of diagnostic and intervention methods has led to the emergence of subspecialties in pain and intensive care, neuro anesthesia, pediatric anesthesia, obstetric anesthesia, local anesthesia, transplantation and cardiovascular and thoracic anesthesia, which are of interest to us in this document [6-7].

The latter has reported the accelerating development of cardiovascular surgery by providing a safe environment and serious care for patients during cardiac surgery. He paved the way for new techniques such as minimally invasive surgery, vascular procedures, and percutaneous interventions on heart valves. He collaborated in developing systems in the field of electrophysiology and interventional cardiology, especially in children. Thus, as part of the multidisciplinary team in managing cardiac patients in surgery, the development of cardiovascular anesthesia has influenced postoperative diagnosis by implementing new anesthesia techniques [8-9].

There is a constant increase in the number of patients with complex forms of coronary artery disease and polymaths, which significantly increases the risks of the perioperative period. In this regard, the contribution of the anesthesiologist to the outcome of the surgeon's rational treatment for coronary heart disease is significant. Despite access to evidence-based copper-based cardiac surgery, anesthesia, and perfusion [10].

All current programs in Cardiovascular Anesthesia are of high academic quality, have a duration of one year for general anesthesiologists, and are grounded in educational programs with similar goals and the development of knowledge, skills, abilities, and attitudes, which are within the framework of professional practice allow the application of knowledge to identify, interpret and solve problems in everyday situations or Unexpected quality, efficiency and a high human sense according to specific contexts. Here are some characteristics of training programs in cardiovascular and aesthesia [11].

The Effect of Anesthesia on Angina Pectoris

A recent study reported that the odds of significant and negative heart complications after major non-cardiac surgery are higher than previously thought. One in five patients classified before the operation as “high-risk” when they undergo “major non-cardiac surgery” will develop one or more cardiac complications within a year.

Globally, more than 300 million non-cardiac surgeries are performed annually. Cardiac complications are a significant cause of Morbidity and Mortality for patients after surgery, especially in substantial surgeries [12].

According to medical statistics, more than 10 million patients annually and worldwide suffer from health-important cardiac events in the so-called "perioperative period." And the “perioperative period” is the period before and after the actual period of stay of the patient on the operating table for the non-cardiac surgery intraoperative period. And that every year, more than one million adults die within 30 days of undergoing non-cardiac surgery [13]. The occurrence of a state of “low oxygen supply to the heart muscle,” or what is medically known as “myocardial ischemia” (whether or not it develops to myocardial infarction), is the most common and deepest cardiac complication in non-cardiac surgery patients. In international statistics, the incidence of a heart attack in the period of “perioperative MI” varies between 1 and 17%, according to the accuracy in conducting statistics in different places in the world, and the level of medical care that patients receive before, during and after non-cardiac surgery [14-15].

Patient Sample 

M collected 40 patients from Baghdad Hospital, where all available data were obtained from height and age, weight and body mass index were calculated about where to determine the effects of anesthesia on heart disease, and all results were recorded in addition to a statistical analysis.

Research Design 

Examined 40 patients with angina pectoris with multiple (from 3 or more) lesions to coronary arteries, but without damage to the stem cortex narcotic artery and groups were divided into 3, and all the necessary and required effects were measured.

We included randomized controlled clinical trials on adults who underwent cardiac surgery under general anesthesia with or without cardiopulmonary bypass. The comparison was made to anesthesia and its effect on cardiac surgery. The average age of the participants was from 40 to 65 years.

Arrhythmia poses a risk in terms of the development of arrhythmias and circulatory disorders during surgery. After all, arrhythmias are possible due to the effect on the heart muscle of anesthetic drugs.

Study Period 

All information was provided from Baghdad Hospital, where the research period was between 2-2-2018 to 3-9-2020.

Aim of Research 

The research aims to determine the location of the effects of anesthesia on heart disease; the author focuses on a specific condition, present in a group of heart diseases where, firstly, repercussions at the level of different systems are described, and then later focuses on those congenital diseases, which produce the condition, and thus can accompany The candidate patient for non-cardiac surgery and in these cases raises anesthesia concerns that must be considered to achieve the best clinical outcome.

Among the 40 patients studied, those who received combined general and epidural anesthesia showed better outcomes, including improved heart function, fewer arrhythmias, and shorter ventilation times. This group also experienced more stable hemodynamics and reduced postoperative pain compared to those who received general or epidural anesthesia alone.

        The study found that patients who received combined general and epidural anesthesia had a lower incidence of myocardial ischemia and better postoperative recovery. This group also showed improved cardiac output and reduced need for inotropic support compared to the other groups.

All patients were characterized by a sharp decrease in myocardial reserve and coronary artery loss - the ejection fraction ranged, and the difference was between 15%. A group of patients using the Inhalational anesthetic compared to the groups with the other groups was characterized by:

The fastest rate of warming during IR in all groups in the pre-perfusion period There were signs of heart failure in several inotropic observations under Support Volatile anesthetics are known to have a negative inotropic effect Against narcotics or other drugs; it can cause Allergic reactions such as skin redness, itching or swelling, feeling sick, or cough. Severe reactions such as shortness of breath, convulsions, heart palpitations, or later serious damage to the circulatory path can remain very rare for some organs, such as brain damage, paralysis, impaired kidney function, and injury to large blood vessels near the puncture site.

Blood clots or clots can form, which can cause blockages in a blood vessel. The clots can also travel to the blood vessels of other members. (Blood vessel obstruction). Thus, for example, this can be done. It causes a clot, kidney failure, or pulmonary embolism, with damage remaining. To prevent Risks, A blood thinner will be given. Suppose bleeding or bleeding continues after the surgery. In that case, heparin will be given to avoid an excessive reaction to the device Immunodeficiency (HIT) (by forming platelet agglutinin), which can block veins and arteries.

Cardiac arrhythmias can cause sudden death. In most cases, this occurs due to the development of ventricular tachycardia with the transition to ventricular fibrillation; less often - due to atrioventricular (AV-) blockade, which is 17% of cases are accompanied by sudden, short-term loss of consciousness [2]. In addition, arrhythmias can be accompanied by severe symptoms such as angina pectoris, shortness of breath, episodes of loss of consciousness, and cardiogenic shock that can lead to decompensation and death.

Effective pain relief and shortening the duration of postoperative ventilatory ventilation are critical components of early rehabilitation of patients after cardiac surgery. This approach shortens the time spent in the intensive care unit and reduces economic costs. The administration of local epidural anesthesia improves the quality of perioperative analgesia for diversion—coronary artery, which was confirmed by several studies. In addition, epidural analgesia during coronary artery bypass grafting improves arterial oxygenation and reduces the duration of mechanical ventilation. These effects were confirmed in a recent meta-analysis and are an additional reason for the broader use of CNS techniques in cardiac surgery. User, after cardiac surgery, a lower anesthesia concentration is used for epidural analgesia than the surgery period. For example, in our study of VHEA in beating CABG, the post-intervention concentration decreased from 0.75 to 0.2%. At the same time, the injection method of administration, including in the self-anesthetized setting, can significantly improve the quality of anesthesia.

Given that the sympathetic nervous system affects the properties of the heart muscle, it is reasonable to assume that sympathy will alter the functioning of the heart muscle. Studies of left ventricular systolic function have shown mixed results. At the same time, almost all work on the assessment of myocardial performance used echocardiographic parameters. Several studies of epidural anesthesia have shown an improvement in the systolic function of the heart, which was manifested by an increase in the cardiac index, stroke volume, and ejection fraction. In some studies, the diastolic function of the myocardium was also assessed using trans esophageal echocardiography. In most of them, improvement in left ventricular relaxation is observed against the background of epidural anesthesia. However, there is evidence of a possible adverse effect of sympathectomy on the myocardium. Thus, several publications have shown a deterioration in its systolic function against the background of the administration of local epidural anesthesia. Most likely, this effect may be due to pharmacological anesthesia of the myocardium by local anesthesia.

Two types of reflexes provide the short-term regulation of blood pressure, and a high epidural mass changes the sensitivity of the pressure reflex in different directions. Thus, in a study of volunteers, HHEA was shown to reduce the sensitivity of baroreceptors in case of increased pressure. Still, it does not change their sensitivity with a decrease in blood pressure (depression test). When epidural and general anesthesia were combined, two studies showed similar results in reducing the intensity of the heart rate response (HR) to the depression test compared to general anesthesia, and other authors obtained opposite results.

Recommendation 

Anesthesia offers advantages that other intravenous analgesics do not necessarily have:

• The block can be used as a supplement or alternative to general anesthesia during surgical operations

• Reducing the sympathetic tone provided by regional blocks can improve local or systemic hemodynamics. Thus, the prevention of tachycardia and hypertension after topical block

• May reduce cardiac morbidity due to increased myocardial oxygen consumption

• The duration of changes caused by local anesthesia varies depending on the nature of the surgery being performed. Several studies show that these changes can be modified or even abolished during an epidural block; In general, the greater the obstruction, the greater the pressure response

• Epidural and spinal blocks for lower limb orthotics are associated with a lower incidence of postoperative deep vein thrombosis and pulmonary embolism
