Differential Diagnosis

For each “chief complaint,” doctors start to immediately compile a mental list of possible causes.  For chest pain, this list is long – much longer than I can possibly cover in an episode.  But we can break down some of the more common causes to a few main organs as possible culprits:

1.        Heart:  Understandably, heart causes of chest pain are the most worrying.  Typical chest pain that is related to the heart begins in the middle or left side of the chest, can radiate up to the jaw, neck, or down the arm, can be accompanied by nausea, vomiting, heart palpitations, or the sweats, and occurs with exertion and is relieved by rest.  But it’s important to note that some patients can present atypically, especially women, those with long-standing diabetes, and the elderly.  Therefore, for those aged 40 or older, and especially those with risk factors, it’s important to consider the heart when faced with a chief complaint of chest pain.

When considering this as a possibility for Calvin, I ran a mental checklist of risk factors for heart disease when speaking to him.  These include:

·         High blood pressure

·         Diabetes

·         Smoking

·         Family history of heart attack or stroke

·         High cholesterol

·         Obesity

Calvin does suffer from high blood pressure, although it is well-controlled with medication at the moment.  And he is overweight and rather sedentary.  His father also suffered from a heart attack at an early age.  So heart disease does run through my mind as a possible cause for his chest pain.  But he does not have diabetes, his cholesterol is normal, and he doesn’t smoke.

As a note, heart attack in a young patient (less than age 40) is not common – unless there is cocaine or methamphetamine use involved. 

Also, other anatomical changes can cause chest pain as well – such as structural heart valve abnormalities and problems with the aorta (the big blood vessel attached to the heart).  So can inflammation or infection of the heart (called myocarditis) or the inflammation of the lining of the heart (called pericarditis).  But these causes of chest pain are not as common.

2.        Lung:  The lungs are very close in proximity to the heart, and therefore symptoms can overlap or mimic each other.  Thankfully, Calvin has never been a smoker and he also is not experiencing any problems with his breathing – no shortness of breath or coughing, which would make me think of possible lung causes.  Here are a few lung problems that can also cause chest pain:

·         Pulmonary Emboli:  This is a clot in the lung that typically travels from the leg.  It occurs in those with a personal or family history of clotting disorders, or in patients with recent history of inactivity (like right after hip or leg surgery, or recent travel on an airplane).  This typically causes a sudden onset of symptoms, often includes shortness of breath, and usually symptoms don’t just come and go.  Some patients also report a swelling in one leg, along with possible pain.  This doesn’t sound like Calvin’s situation at all.

·         Pneumothorax:  This is a hole in the lung that is often caused by trauma (but can also be spontaneous).  Again, this is also typically sudden in onset and doesn’t just come and go.  It tends to be more severe, and also associated with shortness of breath.  This also doesn’t sound like Calvin.

·         Pneumonia:  Patients with pneumonia can have chest pain, but they often also report fevers, chills, cough, and overall malaise.  Calvin’s chest pain doesn’t seem infectious.

3.        Stomach:  The stomach sits right below the chest, and is connected to the esophagus (the tube that carries food down from the mouth into the stomach).  Therefore, patients who experience acid reflux often report it feeling like chest pain as well.  Upon further questioning, Calvin tells me that he hasn’t tried taking any antacids to see if that relieves his chest pains at nights.  But he says he doesn’t sense any acid reflux.

4.       Musculoskeletal:  The rib cage, muscles, and nerves all encase the heart and lungs.  And when doing heavy lifting or strenuous movement with our upper bodies, we can also strain these areas.  Patients will often report chest pain, and the pain is said to be “reproducible” (meaning we can trigger it) by touching it or with certain movements.   Some patients will say that it hurts more when they take a deep breath as well.  Calvin’s pain is not reproducible by the touch or triggered with deep breaths, and he hasn’t been doing anything strenuous.

5.        AnxietyAnxiety and stress can certainly cause chest pain in some patients.  Patients who experience panic attacks, attacks of severe anxiety, often include chest pain as a symptom, along with shortness of breath, sweating, heart racing, and an feeling of intense “impending doom” where they feel like they're going to die in that moment.  This is particularly a concern in young people with chest pain, because panic attacks often begin when young.  Although symptoms can really mimic heart etiologies of chest pain, and therefore these patients should be evaluated promptly.

Diagnosis

Deciding what tests to run on a patient who presents with chest pain depends on many factors – their age, their personal medical history, their history of present illness, their family history, their vital signs in clinic (blood pressure, pulse, weight, oxygenation level, etc.), and the results of the physical exam.  So you can see that it takes a good deal of information gathering, before deciding on what tests to run.  Depending on the information available, doctors may run an EKG, a blood test, a stress test, a chest x-ray, an ultrasound of the heart, or possibility nothing at all. 

Mystery Diagnosis Revealed

Because Calvin had several risk factors for heart disease, I sent him for a stress test – this is a special test in which we “stress” the heart to see if it is the cause of his pain.  His test was thankfully normal.

He has been experiencing a good deal of stress, but he has never experienced panic attacks in the past and he’s 48 years old (a little older than the typical onset of panic disorder, although possible).  Before I blame anxiety (which he is obviously experiencing) I decide to dig a little deeper.  Upon further questioning, he admitted that he’s been drinking 4-6 cups of coffee a day while putting in long hours at work, and eating spicy foods every day at a new local Mexican restaurant by his job and has been experiencing some heartburn after his meals. 

He didn’t think anything of it since he didn’t sense acid reflux, but he did admit that his chest pain occurs when he's lying down and improves upon sitting up at night.  Not all patients actually “sense” the acidic contents of the stomach refluxing up into the mouth.  He also lives a rather sedentary lifestyle, is overweight, and consumes a good amount of foods that trigger acid reflux.   After changing his diet significantly, having him sleep more upright at nights, and temporarily prescribing a medication that decreases the acidity of the stomach, his night time chest discomfort disappeared.

Although the possibilities of chest pain are long, it’s very important that you don’t ignore chest pain.  Chest pain is one of those symptoms that doctors take very seriously, and is rather challenging to dissect – therefore, it’s vital that you seek your doctor right away for a thorough history, exam, and possible tests.
