Fever after heart attack
“rheumatic heart disease” by emmanuel rusingiza, md, for
The researchers discovered a connection between the patient’s highest postoperative temperature during the first 24 hours in the intensive care unit and severe cognitive impairment, as assessed by a battery of cognitive and psychological tests administered before and after surgery. Six weeks after bypass surgery, 39% of the patients in their study were found to have cognitive deficits.
“While this research does not address whether cognitive decline occurs as a result of hyperthermia or whether cognitive decline and hyperthermia are triggered by the same underlying mechanism,” he added. “Clearly, this is a normal occurrence, and one in which we might be able to intervene to enhance the cerebral outcome of patients undergoing heart surgery.”
Although several patients who have some form of surgery develop hyperthermia within one to three days of surgery, Grocott claims that bypass patients develop elevated temperatures much faster, within eight to ten hours of surgery. While the exact cause of hyperthermia is unknown, he believes the body’s inflammatory response to surgery, which is particularly pronounced after bypass surgery, is likely to be involved.

Following a heart attack, two forms of pericarditis may develop.

Pericarditis in its early stages: This form usually appears 1 to 3 days after a heart attack. As the body attempts to clean up the diseased heart tissue, inflammation and swelling occur. Dressler syndrome is another name for late pericarditis. It’s also known as postcardiotomy pericarditis or post-cardiac injury syndrome. It usually appears weeks or months after a heart attack, heart surgery, or some type of heart trauma. It can also occur up to a week after a heart attack. Dressler syndrome is believed to be caused by the immune system mistakenly attacking healthy heart tissue. Pericarditis can be caused by a variety of factors, including: Signs and Symptoms
Using a stethoscope, the health care provider will listen to the heart and lungs. There could be a rubbing noise (called a pericardial friction rub, not to be confused with a heart murmur). Heart sounds may be weak or distant in general. After a heart attack, a buildup of fluid in the heart’s covering or the area around the lungs (pericardial effusion) is uncommon. However, it is common in some people with Dressler syndrome. The following tests can be performed:Treatment
Rheumatic heart disease
Your heart is a muscle that pumps oxygenated blood across your body 24 hours a day, seven days a week. The heart muscle may be weakened or stiffened as a result of such factors. The heart beats inefficiently as this happens. When the heart can no longer pump enough blood to satisfy the body’s needs, it is said to be in heart failure. Heart failure is caused by a number of factors, including:
Penn’s cardiovascular imaging facilities use cutting-edge technology to assist the heart failure specialist in making a precise diagnosis. Ejection fraction is a calculation that determines how much blood the left ventricle pumps out for each beat. The ejection fraction is calculated using the following formula:
Heart failure comes in various degrees. Mild heart disease may be treated with medication or lifestyle changes. Penn’s Primary Cardiology Program experts will assist you in making improvements to slow or stop the progression of heart failure.
Implantable devices such as pacemakers and implantable cardioverter defibrillators are among the treatment choices (ICDs). These devices can help your heart pump enough blood and provide symptom relief.

Although any body temperature above 37.5 °C is considered abnormally warm, temperatures of at least 38.3 °C are referred to as “fever.” This use has evolved over time and can indicate varying degrees of disease severity. However, in the elderly, the rise in temperature associated with infection is less pronounced, so infection may occur at normal temperatures or even in hypothermia (2).
Fever is caused by a change in the hypothalamus’ temperature set-point. This causes systemic reactions, such as peripheral vasoconstriction, which help to increase body temperature. Muscle tremors (shivering) and an unknown amount of thermogenesis in brown adipose tissue are two other mechanisms for producing heat by mechanical means (3).
Fever must be distinguished from hyperthermia, which occurs when the body temperature rises despite no change in the temperature set-point. Hyperthermia is characterized by a core body temperature of less than 40 degrees Celsius, as well as neurological symptoms (4). Hyperthermia may occur as a result of physical activity in unfavorable conditions (for example, sports on a hot day) or in other circumstances that disrupt the body’s thermoregulation (e.g., too little fluid intake and subsequent reduced perspiration in the elderly).
