A pooled analysis of randomized trials found improved cardiorespiratory fitness in people with coronary heart disease compared with non-exercise control. A separate pooled analysis whose designs were not recorded reported that some exercise modalities changed triglycerides or total cholesterol in people with SCAD receiving stable statin therapy.

Evidence tier — overall strength of the evidence for the whole compound

StrongWell established — backed by strong, consistent human research.
ModerateSome genuine support, but mostly from small or lower-quality studies. Promising, not proven.
PreliminaryEarly-stage evidence — a promising hypothesis, not an established effect yet.
LimitedVery limited evidence — treat this as a hypothesis, not proof.
InsufficientNot enough good evidence to draw conclusions yet.

Certainty — how sure we can be that the effect is real

Very highVery sure — strong, consistent evidence
HighFairly sure — consistent evidence from good studies
MediumModerately sure — new studies could change this
LowNot sure — little or mixed evidence
Very lowVery unsure — almost no usable evidence

Source — where the data comes from

Meta-analysisPooled analysis of many trials — the strongest evidence
RCTRandomized controlled trial — a strong human study design
ClinicalA human clinical study
Reference knowledgeFrom general health-science or pharmacology references, not a study of this exact claim
Animal researchStudied in animals, not humans
Community reportsAggregated user reports — anecdotal signal, not evidence
TheoreticalMechanism-based reasoning, not yet tested

Study grade — quality of each underlying study (A best, D weakest)

AHigh-quality — strong, consistent human trials
BGood — solid evidence with some limitations
CModerate — limited, small, or mixed-quality studies

Confidence — how strongly the sources back a finding

A 0–100 score from study quality and agreement

Most supplement evidence is graded C–D. Read it as preliminary signal, not proof.

Full write-up

What is it

Coronary Artery Disease is a cardiovascular condition. Research involving it may assess physical capacity, cardiovascular measures, and emotional well-being, but these are outcomes used to evaluate the condition—not the condition itself. The evidence summarized here applies to people studied with Coronary Artery Disease and may not represent every person with the condition.

Evidence-backed options

The evidence associated with Coronary Artery Disease spans movement-based, dietary, supplement, and sauna-related options, but these findings are not equally applicable. Tai Chi has been studied directly in people with a clinical condition, whereas several supplement findings come from populations whose health status was not specified. Curcumin evidence includes animal research, so its reported effects should not be treated as established effects in people with Coronary Artery Disease.

The regimens described are varied rather than standardized. Examples include curcumin doses ranging from 10 to 200 mg/kg BW per day in animal studies, with 200 mg/kg BW per day identified as the optimal dose in that model; quercetin at 120 mg/day; and flaxseed oil in a milk emulsion containing 2.5 g of ALA. These amounts and formulations should not be assumed to be interchangeable with products or approaches used in clinical care. For many of the other options, the available findings do not specify a dose, treatment duration, or standardized preparation.

The available findings also do not establish a consistent timeline for benefit. They describe changes in exercise capacity, cardiovascular measurements, oxidative-stress markers, risk estimates, or clinical outcomes, but do not provide a common onset time across options. Sauna research is particularly mixed in its design and findings, combining observational evidence with an 8-week RCT that found no significant improvement but no harm in the reported population. Overall, evidence is thinner for options supported mainly by reviews, non-specified populations, or animal studies. Coronary Artery Disease is a medical condition, so these findings are best interpreted with a clinician who can consider the individual’s diagnosis and treatment.

What to avoid

For coronary artery disease, Coffee Enema is flagged because caffeine-related increases in heart rate and blood pressure may increase myocardial oxygen demand or provoke ischemic symptoms. The concern relates to cardiovascular strain rather than the procedure being a neutral source of caffeine exposure.

Cigarette Smoking is flagged because it accelerates atherosclerosis, promotes thrombosis, and increases the risk of myocardial infarction and sudden cardiac death in people with coronary artery disease. These effects involve several processes that can worsen the underlying disease and its cardiovascular consequences.

Ice Bath / Cold Plunge is flagged because sudden deaths among triathletes have been associated with cardiac abnormalities and cardiac pathology. Authors recommend pre-screening of middle-aged triathlon and endurance athletes, making this concern especially relevant when coronary artery disease or other cardiac abnormalities may be present.

These cautions address different cardiovascular risks, including increased oxygen demand, progression of arterial disease, clot formation, and cardiac abnormalities associated with sudden death. Anyone with a medical condition should discuss the relevance of these activities or exposures with a clinician.
