What is Stress Cardiac MRI?

Stress cardiac magnetic resonance imaging (Stress CMR) is a non-invasive functional imaging modality that combines first-pass myocardial perfusion imaging during pharmacologic stress with rest perfusion, cine wall motion and late gadolinium enhancement (LGE). Vasodilator agents (adenosine, regadenoson) maximize coronary flow to detect inducible perfusion defects, while dobutamine elicits wall-motion abnormalities for low-risk patients with contrast contraindications.

It is especially valuable in patients with intermediate pretest probability of CAD, prior equivocal nuclear or echocardiography studies, suspected microvascular angina (INOCA), women with atypical chest pain and patients requiring viability assessment alongside ischemia. CE-MARC, MR-INFORM and STIC trials confirm non-inferiority to nuclear perfusion and demonstrate cost-effective gatekeeper role over invasive angiography.

Symptoms

Atypical chest pain with intermediate CAD risk
Suspected microvascular angina or coronary spasm
Equivocal stress echocardiography or nuclear perfusion
Need for combined viability and ischemia assessment
Women with non-obstructive coronary disease
Pre-operative cardiovascular risk evaluation
Suspected scar after STEMI requiring viability
Cardiomyopathy workup with ischemia question

Risk Factors

Severe asthma or COPD (adenosine contraindication)
High-grade atrioventricular block (without pacemaker)
Severe hypotension or systolic BP < 90 mmHg
Recent acute coronary syndrome (within 48 hours)
Severe aortic stenosis (dobutamine contraindication)
Severe left ventricular hypertrophy or HCM (dobutamine)
Pregnancy (gadolinium relative contraindication)
Non-MRI-compatible implants or claustrophobia

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • Atypical chest pain with risk factors
  • Equivocal previous stress test results
  • Symptoms persisting despite normal coronary angiography
  • Suspected microvascular dysfunction
  • Need for non-invasive ischemia and viability assessment
  • Cardiomyopathy with possible ischemic component
  • Women with chest pain and no obstructive CAD

Treatment Methods

01
Pre-procedure caffeine avoidance for 12-24 hours
02
Discontinuation of dipyridamole, theophylline before adenosine
03
Continuous ECG, blood pressure and oximetry monitoring
04
Adenosine 140 µg/kg/min infusion or regadenoson 0.4 mg bolus
05
Dobutamine graded infusion for selected patients
06
First-pass perfusion imaging during stress and rest
07
Cine balanced SSFP for wall motion analysis
08
Late gadolinium enhancement for scar and viability
09
Quantitative myocardial blood flow analysis when available
