What is refractory cardiogenic shock?
Refractory cardiogenic shock presents as persistent tissue hypoperfusion despite administration of adequate doses of two vasoactive medications and treatment of the underlying aetiology. Investigators of the SHOCK trial reported a long-term mortality benefit of emergency revascularization for shock complicating AMI.
What is the first line treatment for cardiogenic shock?
Medications to treat cardiogenic shock are given to increase your heart’s pumping ability and reduce the risk of blood clots. Vasopressors. These medications are used to treat low blood pressure. They include dopamine, epinephrine (Adrenaline, Auvi-Q), norepinephrine (Levophed) and others.
What is intrinsic cardiogenic shock?
Cardiogenic shock is characterized by primary myocardial dysfunction resulting in the inability of the heart to maintain adequate cardiac output. These patients demonstrate clinical signs of low cardiac output, with evidence of adequate intravascular volume.
What is progressive cardiogenic shock?
Cardiogenic shock is a life-threatening condition in which your heart suddenly can’t pump enough blood to meet your body’s needs. The condition is most often caused by a severe heart attack, but not everyone who has a heart attack has cardiogenic shock.
What causes refractory septic shock?
Septic shock is a life-threatening condition that happens when your blood pressure drops to a dangerously low level after an infection. Any type of bacteria can cause the infection. Fungi such as candida and viruses can also be a cause, although this is rare. At first the infection can lead to a reaction called sepsis.
What does refractory septic shock mean?
Refractory septic shock is variably defined as the presence of hypotension, with end-organ dysfunction, requiring high-dose vasopressor support often greater than 0.5 μg/kg/min norepinephrine or equivalent . Regardless of the precise definition, there is an associated mortality of up to 60%.
What is the goal in treating cardiogenic shock?
The goal of cardiogenic shock treatment is to quickly restore blood pressure and heart function. This often requires a series of immediate treatments that are given in an ambulance or the emergency room.
What is the difference between cardiogenic and hypovolemic shock?
Cardiogenic shock (due to heart problems) Hypovolemic shock (caused by too little blood volume)
What is the meaning of hypovolemic shock?
Hypovolemic shock is an emergency condition in which severe blood or other fluid loss makes the heart unable to pump enough blood to the body. This type of shock can cause many organs to stop working.
What are signs of cardiogenic shock?
Cardiogenic Shock Signs and Symptoms
- Rapid breathing.
- Severe shortness of breath.
- Sudden, rapid heartbeat (tachycardia)
- Loss of consciousness.
- Weak pulse.
- Low blood pressure (hypotension)
- Pale skin.
What are the four stages of cardiogenic shock?
There are four stages of cardiogenic shock: initial, compensatory, progressive, and refractory. During the initial stage, there is diminished cardiac output without any clinical symptoms.
