Blockage Reversal Evidence

Scientific Literature

The controversy surrounding the possibility of reversal of coronary artery disease has been put to rest by multiple well-conducted scientific trials. Let us now discuss some of the best evidence that supports the fact that blockage reversal is possible.


1. Whole Foods plant-based diet for coronary artery disease reversal

In 1995, Caldwell Esselstyn, published the results of a small but well-conducted study to demonstrate the power of the whole foot plant-based diet and reversal of blockages. (1) Significant angiographic reversal in the blockages were seen with diet control alone. The evidence was again replicated in a larger trial of 198 patients in 2014. One criticism of the study was that the strict dietary regimen excluded all dairy, meat, and oils and was therefore impractical. However, the fact remains that the patients recruited in the trial underwent intensive counseling, and a compliance rate of 87% was achieved. 


2. Lifestyle transformation trial for coronary artery disease reversal

Dean Ornish 1998 published his data on intensive lifestyle changes for the reversal of coronary heart disease. This randomized controlled trial included 48 patients. The intervention consisted of intensive lifestyle changes including a vegetarian diet with less than 10% fat, exercise, stress management training, smoking cessation, and group psychosocial support for five years. All patients underwent coronary angiography before and after the trial period. More regression of coronary atherosclerosis occurred in the intervention arm compared to the control arm. The improvement in blockages was more pronounced after five years than after one year. In contrast, in the control group, coronary atherosclerosis progressed and, more events occurred during the follow-up (4)

 

3. Statin therapy and CAD Reversal

REVERSAL (5) was the first statin trial and demonstrated a halting of the progression of atherosclerosis with high-dose Atorvastatin. The average LDL achieved in the intervention arm was 79. ASTEROID (6), SATURN (7), and PRECISE IVUS (8), were three subsequent trials enrolling over 1500 patients collectively. All three trials demonstrated plaque regression as evaluated by intravascular imaging. The statins used were either Rosuvastatin 40 mg or atorvastatin 80 mg. The LDL levels achieved in the intervention were 63 mg/dl. The plaque regression was evaluated with intravascular ultrasound.
