If the chest pain is caused by too much smoking, it is recommended that the patient stops smoking immediately and goes to the hospital for a complete examination. An 18-lead electrocardiogram (ECG) should be done quickly and the infarction triad should be checked at the same time. If there are problems in the triad of infarction, it is necessary to apply drugs for treatment, for example, the patient can be injected intravenously with nitroglycerin injection, or sublingual nitroglycerin, or the application of isosorbide mononitrate, because too much smoking will cause a large amount of nicotine and tar components to be absorbed and released into the bloodstream, which will lead to an increase in the consumption of oxygen by cardiomyocytes, the heart’s contractility will be increased, and the patient will then have unstable angina. In addition, if too much smoking will also activate the body renin – angiotensin – aldosterone system leading to increased blood pressure, the patient in the blood pressure increase will also appear chest pain symptoms, this time you can take antihypertensive drugs, such as calcium channel blockers or ACEI class drugs.
