One of many first coronary heart assault signs I skilled (together with central chest ache, nausea and ache down my left arm) was profuse sweating. I used to be out for my common early morning stroll on the time, however not going sooner than ordinary or trekking up a steep hill. It was a gentle spring day – simply your common Monday morning stroll alongside the comparatively flat streets of my neighbourhood.
As a former distance runner, I’ve had years of expertise on lengthy very sweaty runs. However sudden sweating throughout a simple flat stroll? That simply doesn’t occur to me. .
Sweating (or what docs wish to name “diaphoresis” to point out they’ve been to medical college) could be a important cardiac warning signal, particularly if it feels “uncommon”. In reality, the highest three mostly reported cardiac signs in each ladies and men are chest ache, sweating and shortness of breath.(1) Chest discomfort (generally however not all the time described as “ache” by ladies) is the commonest warning signal of myocardial infarction (coronary heart assault), reported by about 80 per cent of each ladies and men throughout a coronary heart assault. See additionally: What’s Inflicting My Chest Ache?
Dr. Catherine J. Ryan is the Director of Nursing Analysis on the College of Illinois in Chicago. She and her crew studied these 12 coronary heart assault signs – together with sweating – reported by over 1,000 coronary heart assault survivors:
chest discomfort/ache
shoulder, arm, or hand discomfort
sweating
neck or jaw discomfort
shortness of breath
again discomfort
stomach discomfort
indigestion
nausea/vomiting
dizziness/light-headedness
weak point
excessive fatigue
She reminds us that “breaking out right into a sweat for no obvious motive is one factor that you could’t clarify away” – as we frequently attempt to do with different cardiac signs at first – like shortness of breath (out of practice?), nausea (one thing I ate?), fatigue (all ladies are drained!), and even chest ache (a pulled muscle?)

As Dr. Ryan warned:
“Warning bells ought to ring off if an individual instantly begins sweating profusely.”
Traditionally, cardiologists have known as any symptom that isn’t typical of a male coronary heart drawback (e.g. a lot of these 12 signs on Dr. Ryan’s listing) “atypical”. However given that girls make up over half the inhabitants, our cardiac signs can solely be described as “atypical” for those who in some way imagine that each one cardiac signs ought to be outlined solely by male evaluation requirements.
Dutch researchers, for instance, noticed in 2020 that girls with acute coronary syndrome (ACS, the damaging precursor to a coronary heart assault) could certainly report completely different signs than males with ACS, however there’s additionally appreciable overlap.1 They warned:
“Since these variations have been proven for years, cardiac signs ought to now not be labeled as atypical or typical.”
Dr. Ryan additionally tells us that if we don’t pay nearer consideration – particularly to a “cluster” of signs taking place on the similar time – it virtually all the time means that we’ll delay in search of well timed remedy – which, not surprisingly, can worsen our outcomes throughout a coronary heart assault. Her research discovered that the extra of those “cluster signs” we expertise, the shorter our treatment-seeking delay behaviour will probably be.
In different phrases, we all know that girls are likely to ignore or reduce one or two of their earliest cardiac signs, nevertheless it’s a lot more durable to disregard an entire bunch. And strange sweating – whether or not profuse sweating that doesn’t match the extent of bodily exertion or chilly/clammy sweats – could be a type of signs we must always not ignore.

That “shorter” delay time, by the way in which, nonetheless averaged a whopping 9.7 hours earlier than the center sufferers adopted on this research determined to lastly search emergency assist.
IMPORTANT NOTE: your physique. You KNOW when one thing is simply not proper. Ask your self what you’d do if the identical signs had been taking place to your Mum, or your daughter, or your sister – and take the identical fast actions for your self.
Different research counsel that sweating isn’t restricted to coronary heart assault signs. Italian researchers, for instance, known as sweating “the uncared for sign up coronary heart failure sufferers.” 2 See additionally: Is it Lastly Time to Change the Title ‘Coronary heart FAILURE’?
Sweat evaporation from the pores and skin floor is a fairly essential bodily perform. It’s your physique’s pure cooling mechanism. In individuals who don’t or can’t adequately sweat, physique core temperature can rise sharply with train or warmth stress, which might result in warmth exhaustion or warmth stroke except different life-saving technique of cooling can be found.3
Heavy night time sweats or clammy sweats may also be a cardiac symptom, however many ladies could mistake these as a typical menopause problem. When you get up to seek out the mattress sheets are soaked by way of, or for those who can’t sleep on account of sweating, discuss to your physician.
Why does a cardiac occasion typically trigger uncommon sweating?
In blocked coronary arteries, it takes extra effort in your coronary heart to pump oxygenated blood to the center muscle, so your physique sweats extra to attempt to preserve your physique temperature down throughout that further effort. And as the Italian researchers defined, in sufferers identified with coronary heart failure, their overactive sympathetic nervous system can “generate a sign to the sweat glands to extend the dispersion of fluids.”
When you’ve ever been sick with a excessive fever, you recognize that sweating can accompany an abnormally excessive physique temperature. Fever can even come up in sufferers throughout an acute coronary heart assault. These fevers can peak as early as 4-8 hours after the onset of a coronary heart assault and normally come again down by the fourth to fifth day.4 Submit-infarct fever has been acknowledged as a response to important coronary heart muscle injury.
Bear in mind: by no means attempt to clarify away uncommon sweating if it accompanies chest discomfort. Search rapid medical assist.
