Silent heart attacks:

abstract human heart isolated on black background

On television, heart attacks are portrayed in rather dramatic fashion — typically, an older man clutching his chest with agonizing pain. This mental image is embedded in our culture, but it actually represents only a small fraction of heart attacks. As it turns out, a variety of different symptoms may develop with a heart attack. In addition to chest pain, some of the other symptoms that can occur with a heart attack include chest pressure, chest heaviness, arm pain, neck pain, jaw pain, shortness of breath, sweating, extreme fatigue, dizziness, and nausea. That is, in part, why it is not always so easy to diagnose a heart attack. And of course, women are also at risk for heart attacks. Whether women are more likely than men to have these symptoms other than chest pain remains a controversial point.

Now, research from the Atherosclerosis Risk in Communities (ARIC) Study has found that almost half (45%) of heart attacks appear to be clinically silent — that is, not associated with any symptoms at all, at least that the patient can recall. These sorts of silent heart attacks were picked up by use of a routine electrocardiogram (ECG). And these silent heart attacks weren’t just a meaningless abnormality picked up on a test. The silent heart attacks were associated with a similar risk of subsequent death as clinically detected heart attacks.

Older studies had more or less come up with similar findings. The present study extended these observations into a much more diverse population. The excess risk associated with silent heart attacks was found to be present in both men and women. Of note, rates of both types of heart attack were higher in men than in women. There was also an excess risk of future death associated with both clinical heart attacks and silent heart attacks in both white and African American patients. Other races were not examined in this study, and more work needs to be done in this regard, though likely the results would be similar.

What does this mean for people who are worried about heart attacks? Guidelines for physicians from professional medical societies in general no longer recommend routine ECGs in healthy people, though this used to be a common practice. Certainly, if you should have an ECG for some purpose, such as before certain types of surgery, and a silent heart attack is detected, that needs to be taken seriously — really, as though you had had a clinically apparent heart attack. Any medications and lifestyle changes prescribed as a result of detecting a silent heart attack should also be relatively similar.

Future studies will have to determine if certain populations might benefit from routine screening for silent heart attacks. Beyond any studies done within the world of conventional medical research, the increasing availability of various apps will allow people to get ECGs on themselves, so detection of silent heart attacks will probably increase. The risk of this sort of indiscriminate screening is that one test abnormality might lead to another set of more expensive and risky tests. So, hopefully we can sort our relatively quickly (i.e., in the next few years) who might be best served with routine screening with ECGs, or perhaps even more sophisticated tests to detect silent heart attacks or people at risk for them.


Bible verses for today’s meditation and inspiration: Matthew E. McLaren

Romans 12:2 ESV  Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect.

Philippians 4:8 ESV  Finally, brothers, whatever is true, whatever is honorable, whatever is just, whatever is pure, whatever is lovely, whatever is commendable, if there is any excellence, if there is anything worthy of praise, think about these things.

Isaiah 26:3 ESV You keep him in perfect peace whose mind is stayed on you, because he trusts in you.

2 Corinthians 10:3-6 ESV For though we walk in the flesh, we are not waging war according to the flesh. For the weapons of our warfare are not of the flesh but have divine power to destroy strongholds. We destroy arguments and every lofty opinion raised against the knowledge of God, and take every thought captive to obey Christ, being ready to punish every disobedience, when your obedience is complete.

Philippians 4:4-9 ESV Rejoice in the Lord always; again I will say, Rejoice. Let your reasonableness be known to everyone. The Lord is at hand; do not be anxious about anything, but in everything by prayer and supplication with thanksgiving let your requests be made known to God. And the peace of God, which surpasses all understanding, will guard your hearts and your minds in Christ Jesus. Finally, brothers, whatever is true, whatever is honorable, whatever is just, whatever is pure, whatever is lovely, whatever is commendable, if there is any excellence, if there is anything worthy of praise, think about these things. …

2 Timothy 1:7 ESV For God gave us a spirit not of fear but of power and love and self-control.

Proverbs 4:23 ESV Keep your heart with all vigilance, for from it flow the springs of life.

Romans 12:1-2 ESV I appeal to you therefore, brothers, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship. Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect.

Romans 7:23 ESV But I see in my members another law waging war against the law of my mind and making me captive to the law of sin that dwells in my members.
