Avoid excessive angiography costs for stable coronary artery disease through routine electrocardiogram assessment

Coronary artery disease (CAD) is a leading cause of death worldwide, and the choice of treatment pathways remains highly controversial in clinical practice. The core of the controversy lies in whether, when faced with patients with stable CAD, invasive interventional procedures should be prioritized, or a conservative management approach based on standardized drug therapy and non-invasive tool assessment should be adopted. For a long time, invasive diagnostic and treatment methods, represented by coronary angiography, have been widely used in clinical practice. However, with the accumulation of medical practice and public health data, the conventional wisdom of frequent angiography is beginning to be re-examined.

From the perspective of clinical risk and economic cost, over-reliance on coronary angiography has significant drawbacks. First, angiography is not an absolutely safe diagnostic method; it is an invasive procedure with inherent risks. Clinical data shows that approximately 5% of angiography procedures may be accompanied by serious complications during or after the procedure. These risks include:

Major bleeding at the puncture site:Severe bleeding may occur at the catheter insertion site.

Kidney damage:The contrast agent used in the procedure needs to be metabolized by the kidneys, which may lead to acute kidney problems in some patients.

Serious arrhythmias: When the surgical catheter enters a coronary artery, it may stimulate the heart, causing dangerous cardiac arrhythmias.

Acute myocardial infarction or even death:In rare cases, the procedure may accidentally dislodge plaque in the blood vessel, causing sudden blockage.

Therefore, blindly performing angiography on patients with stable conditions can artificially increase these avoidable medical accidents. Furthermore, the costs of cardiac-related examinations and surgical supplies are high. According to official data from the China Cardiovascular Health and Disease Report, the scale of cardiovascular diagnosis and treatment in my country continues to expand, with coronary heart disease patients accounting for 42% of cardiovascular disease cases. The price of a single coronary angiography ranges from 4,000 to 8,000 yuan, with more complex procedures like stent implantation costing even more. This represents a significant expense for many ordinary families. In complex clinical settings, some angiography examinations lacking clear indications not only expose stable patients who do not require surgery to unnecessary physical risks but also exacerbate the burden on medical insurance funds and family finances.

To improve this situation, clinical practice should fully utilize non-invasive diagnostic tools. In a series of non-invasive assessment procedures, a standard 12-lead electrocardiogram (ECG) plays a fundamental role. For ordinary stable coronary artery disease patients, resting ECG is a basic and important diagnostic tool, quickly providing crucial data such as whether the patient has old myocardial infarction, current ischemic waveforms, and conduction block, serving as a safety basis for all subsequent treatment plans.

In conclusion, clinical management of stable coronary artery disease should avoid the tendency to perform angiography indiscriminately. By strictly and systematically applying basic non-invasive tools such as electrocardiograms, we can not only effectively ensure patient safety and avoid unnecessary surgical trauma, but also significantly reduce the overall burden of national medical consumables and finances on a macro level.
