Irreversible Myocardial Failure Case Study

134 Words1 Pages
The medical complications Mr. Smith may suffer due to the irreversible myocardial damage would be determined by the degree of heart injury after the MI, and the location of cardiac heart muscle damage ( right or left ventricles). Abnormal heart rhythms (arrhythmias) can develop due to damage to the muscles. They can either be mild, such as tachycardia, bradycardia, atrial fibrillation, or severe and fatal, such as a complete heart block, and ventricular arrhythmia. Heart failure due to ineffectively circulation of blood related to damaged cardiac muscles may also occur. Cardiogenic shock can also happen if the heart is no longer able supply sufficient blood to body organs. Heart rupture may happen to areas of the heart weakened by the heart

's health deteriorated as a direct result of the shot to his chest. He had emergency surgery which lead to a narrowing of the aortic valve opening, aortic stenosis. Thus causing D.R. to have poor circulation in his lower extremities and an increase of pressure that could only be relieved surgically. An infection developed in the bone after his second surgery.

The lung tissues may develop a pneumothorax. This causes the lungs to collapse by letting air escape into the chest cavity. This disease may affect the heart through aortic dilation. The aorta is a blood vessel that is responsible for transporting blood from the heart to the body. In aortic dilation, the aorta may overstretch or become weak.

Angina, Myocardial Infarction, and Cardiac Arrest Comparison and Contrast Hannah Bunce Fayetteville Technical Community College Angina, Myocardial Infarction, and Cardiac Arrest Comparison and Contrast Three of the most commonly occurring cardiac related events: angina, myocardial infarction, and cardiac arrest, are commonly confused. However, there is a huge difference between each of them. It is crucial to be informed of each of these cardiovascular emergencies and to be able to differentiate between them. As a medical professional it is also very important to know the appropriate care for each these cardiac related emergencies.

2.Heart failure symptoms can include shortness of breath while sleeping or walking. Symptoms can show signs of chest pain or anxiety from stress. There are multiple signs and symptoms a person should look out for, such as dizziness, fatigue, rapid irregular heartbeat, or even swelling in the ankles, legs, and feet. But, in some cases there may be no symptoms at all. 3.Heart Failure can affect anyone of age, including infants, toddlers, children, teens, adults, and the elderly.

Therefore, compensated heart failure occurs when blood accumulates after the heart contraction that’s means at a higher venous pressure. In case when sympathetic discharge cannot change cardiac output easily and use renal mechanism to restore cardiac output decompensated heart failure occurs. Therefore the main difference between compensated heart failure and decompensated heart failure is in the action of sympathetic discharge that is regulated by sympathetic nervous system. (Cindy L. Stanfield.,2011.) 3.

Besides, left ventricle hypertrophy can also affect the main pumping chamber with thickening of the septum which restricts the blood flow via the aorta to the rest of body. The obstruction decreases coronary perfusion pressure and decreases the cardiac output. Shortness of breath and chest pain are the common signs of hypertrophic obstructive cardiomyopathy. Most importantly, it may cause heart failure. In most cases, heart failure is due to diastolic dysfunction.

What causes the heart to become weaker? There is a number of causes, but most of all, the arteries may narrow in the heart. That is another disease known as Coronary Artery Disease. Another reason that a Congestive Heart Failure may occur is because of high blood pressure.

He was wandering in the desert for 2 months, and disoriented to time, although; he continued to call his daughter’s name, and asked for his wife. He had a number of bruises on his face, and his toes on his right foot were black, in fact the toes fell off. The doctor’s had to auto transplant his kidney, except his BP dropped and the man experienced cardiac arrest. Then they ordered an Echocardiogram, which this disturbed Dr. Pierce, for she suggested that it be done first.

Because of this inability to contract effectively, the rest of the vital organs receive inadequate amount of blood resulting to inadequate tissue perfusion. There are two types of left-sided HF; systolic and diastolic failure. Systolic failure happens when the left ventricle doesn’t have the enough energy to pump normally the blood to the general circulation. As for diastolic failure, the left ventricle loses the ability to fill itself with blood during resting period resulting to inadequate amount of blood to be pumped out to the circulation (Weinrauch, 2008). The diastolic dysfunction will eventually lead to right-sided heart failure.

INTRODUCTION Chest pain is the most usual symptom at presentation in patients with acute myocardial infarction (AMI), even if it ishighly subjective, and the pain characteristics, severity and emotional consequences may vary widely.1, 2 An asymptomatic AMI is not necessarily less severe than a symptomatic event. Diabetic and elderly subjects are those who generally present with a lower severity of chest pain and at the same time represent the subgroups of AMI patients withworse outcome.3 Chest pain characteristics over time may also change in relation to the presence and severity of myocardial ischemia whichdepends on several factors influencing the relationship between myocardium at risk oxygen supply and demand. Oxygen supply during the acute

I enjoyed reading your discussion post and it is very informative. I am glad to hear that everything went well with your past pregnancy and I am happy that you delivered a healthy baby. You brought up a great point about having a serious condition without having any types of symptoms. It is easy to misdiagnose an elderly patient because some of their presenting symptoms are atypical. For example, an elderly patient who is suffering of myocardial infarction might not feel a chest pain.

But the blood flow improves when the body is at rest which would cause nocturia. When he goes for an echocardiogram, he was diagnosed with left ventricular hypertrophy. This is due to the heart remodeling mechanism, where the muscle thickens and was triggered by heart when there is an increased in the workload of the left ventricle.[1] There are a few factors that could contribute to the development of Mr. Rowan’s symptoms. First is the age-related decrease in myocardial and vascular responsiveness to β-adrenergic stimulation that further impairs the ability of the cardiovascular system to respond to increased

In early days prior to developing of a heart lung machine doctors could do nothing except to pray god for the survival of the patient. But after lot of work and research the first successful open heart surgery with the help of heart lung machine was performed by Dr John Gibbon Jr on 6th may 1953 by closing an atrial septal defect using a heart lung machine and a screen oxygenator. Since then there has been lot of advances with regard to the machinery and techniques used for cardiac surgeries which required heart to be stopped to be operated upon. Myocardial protection(MP) plays a very important aspect in open heart surgeries which requires the use of a Heart Lung Machine (HLM) and need the heart to be stopped to correct the defects in the heart.
