Chest pressure, tightness, or heaviness lasting more than 15 minutes without relief — call 120; do not drive yourself.
胸口压着疼、闷、发紧超过 15 分钟不缓解，打 120，不要自己扛也不要自己开车
No cost at all.
If you feel chest pressure, tightness, or heaviness that lasts over 15 minutes without easing up, call 120 right away. For patients treated within 55 minutes of arrival at the hospital, the mortality rate within 30 days is 2.8%. For those treated later than 55 minutes, the rate rises to 9.7%. Every minute of delay means more heart muscle tissue dies. Do not drive yourself — losing consciousness while behind the wheel could lead to a second accident.

The excuse
The routine already works until the day the source says it may not.
What feels good now
Today I keep a few minutes and avoid interrupting my default routine.

Original recommendation and evidence
7. Chest pressure, tightness, or heaviness lasting more than 15 minutes without relief — call 120; do not drive yourself.
Cost: No cost at all.
In plain terms: If you feel chest pressure, tightness, or heaviness that lasts over 15 minutes without easing up, call 120 right away. For patients treated within 55 minutes of arrival at the hospital, the mortality rate within 30 days is 2.8%. For those treated later than 55 minutes, the rate rises to 9.7%. Every minute of delay means more heart muscle tissue dies. Do not drive yourself — losing consciousness while behind the wheel could lead to a second accident.
Benefit: Israel conducted a nationwide study on acute coronary syndrome. The research focused on patients experiencing ST-segment elevation myocardial infarction, a specific type of heart attack. It measured the time interval from hospital admission to the point when a balloon catheter was used to reopen the blocked blood vessel. For patients treated within 55 minutes, 5 out of 178 (2.8%) died within 30 days. For those treated after 55 minutes, 15 out of 155 (9.7%) died within the same timeframe.
Evidence grade: B

Notes: This study compares outcomes based on the time elapsed after hospital admission, not from the onset of symptoms to arrival at the hospital. However, the underlying principle remains the same: any delay results in additional heart muscle damage. The pain may also be felt in the upper abdomen, back, or jaw, and numbness in the left arm can also be a symptom. Diabetic patients and older adults may not experience any pain at all, only shortness of breath. Again, do not drive yourself — losing consciousness while driving can easily cause another accident.

7. 胸口压着疼、闷、发紧超过 15 分钟不缓解，打 120，不要自己扛也不要自己开车
成本: 不花钱。
说人话: 胸口压着疼、闷、发紧，超过 15 分钟不缓解，打 120。到医院后 55 分钟内把血管撑开的，30 天内死亡 2.8%。超过 55 分钟的 9.7%。耽误的每一段，都在多坏死一块心肌。别自己开车，路上失去意识就是第二场事故。
收益: 以色列做过一项全国急性冠脉综合征调查。分析的对象是 ST 段抬高心肌梗死患者，这是一类心梗。算的是从进医院到用球囊把堵住的血管撑开（球囊扩张）这一段间隔。间隔 ≤55 分钟的，30 天内死亡 5/178（2.8%）。间隔 >55 分钟的，30 天内死亡 15/155（9.7%）
证据等级: B

备注: 该研究比的是进了医院之后耽误的那段，不是从发病到进医院那段。但道理一样：每耽误一会儿，就多坏死一块心肌。疼可能疼在上腹、后背、下巴，也可能是左胳膊发麻。糖尿病人和老年人可能不疼，只是喘。不要自己开车，路上失去意识就是第二场事故
