Ten Pearls regarding Coronary Artry Symptoms and Chest
pain.
1- Many patiensts with acute coronary symptoms
do not have classic text book symptoms. Crushing chest pain may indicate a heart attack
in one patient, whereas mild shortness of breath may indicate the same disease process in
another. With age progresses, chest pain declines in frequency as the presenting symptom
however breathlessness, syncopy or stroke become more common. Pain in epigastric area, back,
jaw pain, heart burn is more common among women as compared to men. Remember to keep in mind,
that heart attack symptoms may be atypical like nause vomiting indigestion feeling or may be
abcent especially in women, diabetics and elderly.
2- Angina does not always mean coronary artry
diseas. Left Ventricular out flow track obstruction like aortic stenosis or hypertrophic
obstructive cardiomyopathy can also cause classic angina as may
anemia.
3-Features which make coronary pain unlikely
include stabbing pains, pain lasting less than 30 seconds, localized left inflammatory pain
and having continually varing location.
4- Patienst may use the word sharp to convey
severity of pain rather than as a description of the character of
pain.
5-Don't always assume that change in chest
pain represents unstable angina, nitroglycerine may have lost their potency. Check for
associated symptoms of headache stinging and flushing. Some patients may also be non
compliant with their medications.
6- A high index of suspicion is necessary to
avoid missing the diagnosis of acute aortic dissection or pericarditis. This distinction from
acute Myocardial infarction is essential, scisnce thrombolytic therapy is contraindicated in
these conditions.
7-Ongoing chest pain that has been present for
an extended period of timemay still represent angina. Further questioning of the patient may
reveal that the pain is actually intermittent scince its onset and not
constant.
8-Don't attibute cardiac symptoms to other
chronic underlying conditions, e.g hiatal hernia or esophageal spasm. A history of such an
underlying disease does not rule out a new cardiac condition.
9- Not all patients with acute MI develop ECG
changes. As many as 1/3 do not develop any changes at al.Because ECG changes are not always
seen with acute MI and serum markers may take time to evolve, the key determinant wheather or
not to hospitalize a patient with chest pain remains the clinical
history.
10-Although risk factors for coronary artry
disease are important to keep in mind when evaluating a patient with chest pain, a
significant percentage of patients presenting with acute myocardial infarction may have no
risk factors.
