How to effectively treat chronic myocardial infarction

Patients with chronic myocardial infarction should pay more attention to care and conditioning in their lives, pay attention to rest and bed rest, and keep their living environment quiet. They can also use some pain-relieving drugs according to the situation, but they must follow the doctor's advice.

1. Monitoring and general treatment

1) Rest in bed for 1 week in a quiet environment.

2) Oxygen inhalation through nasal cannula mask.

3) Monitoring: ECG, BP, R for at least 5-7 days, and capillary pressure and venous pressure if necessary

4) Nursing

2. Commonly used drugs for pain relief

1) Pethidine intramuscular injection or morphine subcutaneous injection, preferably in combination with atropine.

2) For mild cases, codeine or opium poppy can be used.

3) Nitroglycerin or isosorbide dinitrate, sublingual or intravenous, pay attention to increased heart rate and hypotension.

4) Chinese herbal preparations.

5) Myocardial reperfusion therapy can also relieve pain

3Reperfusion therapy:

All patients with symptom onset < 12 hours and persistent ST-segment elevation or new left bundle branch block are candidates for reperfusion therapy; if there is evidence of progressive ischemia, reperfusion therapy (primary PCI is preferred) is indicated even if symptom onset is > 12 hours or chest pain and ECG changes persist.

① Direct PCI treatment:

Primary PCI is preferred over thrombolytic therapy if performed by an experienced team within 120 minutes of first medical contact; primary PCI is indicated in patients with severe heart failure or cardiogenic shock unless long delays are expected and the patient presents early after symptom onset; stenting is preferred over balloon angioplasty alone during primary PCI;
