✅ Myocardial infarction
🧿 A myocardial infarction (MI) occurs when a thrombus blocks blood flow through a coronary artery, depriving the heart muscle of oxygen.
🧿 Prolonged interruption of blood flow causes ischemia followed by necrosis of the myocardium.
🧿 Clients may experience chest pain, shortness of breath, diaphoresis, nausea, and electrocardiographic changes.
🧿 Untreated myocardial infarction can lead to cardiogenic shock, life-threatening dysrhythmias, heart failure, and sudden cardiac death.
🧿 Rapid restoration of coronary blood flow through percutaneous coronary intervention (PCI) or thrombolytic therapy, when appropriate, improves survival.
🧿 Nurses should recognize symptoms promptly and activate emergency treatment protocols without delay.
🧿 Early intervention minimizes permanent myocardial damage and improves long-term cardiac function.
🧿 Myocardial infarction is a life-threatening thromboembolic emergency requiring immediate treatment.
✅ Ischemic stroke
🧿 An ischemic stroke occurs when a thrombus or embolus obstructs blood flow to part of the brain.
🧿 Brain tissue deprived of oxygen begins to die within minutes, making this a true medical emergency.
🧿 Common manifestations include facial drooping, arm weakness, speech difficulty, vision changes, and altered consciousness.
🧿 Prompt recognition using the FAST assessment allows rapid treatment and improves neurological outcomes.
🧿 Eligible clients may receive thrombolytic therapy or undergo mechanical thrombectomy to restore cerebral blood flow.
🧿 Delayed treatment increases the risk of permanent neurological deficits or death.
🧿 Rapid intervention preserves brain tissue and maximizes recovery potential.
🧿 Ischemic stroke is a life-threatening condition caused by blocked cerebral blood flow.
✅ Pulmonary embolism
🧿 A pulmonary embolism (PE) occurs when a blood clot, often originating from a deep vein thrombosis, travels to the pulmonary arteries.
🧿 The clot obstructs pulmonary circulation, reducing oxygen exchange and increasing strain on the right ventricle.
🧿 Manifestations include sudden dyspnea, pleuritic chest pain, tachycardia, hypoxemia, and sometimes hemoptysis.
🧿 A large pulmonary embolism can rapidly cause obstructive shock, cardiac arrest, and death if not treated promptly.
🧿 Immediate treatment may include oxygen therapy, anticoagulation, thrombolytic therapy, or embolectomy, depending on severity.
🧿 Early diagnosis and intervention significantly reduce mortality.
🧿 Nurses should recognize pulmonary embolism as one of the most serious complications of venous thromboembolism.
🧿 Pulmonary embolism is a life-threatening complication requiring immediate emergency management.
