Mayor of Belo Horizonte, Fuad Noman, died on Wednesday (26) after a cardiogenic shock. The politician had a cardiorespiratory arrest on Tuesday (25), but was revived, however did not resist. He was hospitalized at the Mater Dei Hospital Intensive Care Unit (ICU) since January 3, when he was admitted to a severe acute respiratory failure, due to the non-Hodgkin lymphome he was dealing with.
Cardiogenic shock is the name given to the hypoperfusion frame, ie when blood flow is lower than normal. It usually occurs after serious infarcts, but is considered a rare condition. According to Mayo Clinicreference clinic in the United States, when treated immediately, about half of the people who develop the condition survive.
How does cardiogenic shock occur?
In most cases, cardogenic shock occurs when there is a lack of oxygen in the heart – which is common after a heart attack. This damages the left ventricle (considered the main pumping camera of the organ) and weakens the cardiac muscle, causing the condition.
With these changes in the heart, there is a reduction in blood pressure (hypotension), which makes the arteries and veins compress, also reducing circulation to peripheral tissues and later to the heart.
Cardiogenic shock is more common in patients than:
- They are older;
- It has history of heart failure or heart attack;
- It has blocks (coronary artery disease) in several of the main arteries of your heart;
- He has diabetes or high blood pressure;
- They are women.
CAUSES OF CARDIGENIC SHOCK
The possible causes of cardiogenic shock include:
- Heart attack;
- Inflammation of the cardiac muscle (myocarditis);
- Heart valve infection (endocarditis);
- Heart weakened by any cause;
- Drug overdoses or poisoning with substances that can affect the pumping capacity of your heart.
Generally, cardiogenic shock is a complication of between 5% and 10% of cases of acute myocardial infarction, being the main cause of death after these events, as explained Article of the American Association of the Heart.
Symptoms of cardiogenic shock
In general, the patient with cardiogenic shock will show signs such as:
- Changed mental state;
- Hypotension;
- Arrhythmia;
- Decreased pulses;
- Dyspnea;
- Peripheral edema.
Usually the condition is treated in hospital, with medications and therapies. Surgeries, such as coronary artery bypass, may be necessary.
