Chronic Stable Angina Remedies (Evidence-Based)

Chronic stable angina is a recurring form of chest discomfort that results due to the heart muscle not receiving enough oxygen-rich blood to meet its needs. It most commonly occurs in people with coronary artery disease (CAD) and follows a relatively predictable pattern. Symptoms often appear during physical activity or emotional stress and improve with rest or anti-anginal medication.

Stable angina falls under the broader category of chronic coronary syndromes (CCS) –  conditions involving structural or functional abnormalities of the coronary arteries or microcirculation that can create a temporary mis-function between oxygen supply and demand in the heart.

In this article, I go over everything you need to know to understand the condition as well as evidence-based natural remedies.

What Is Chronic Stable Angina?

Stable angina typically:

  • Occurs during exertion or any activity or experience resulting in increased cardiac activity.
  • Occurs in a somewhat predictable pattern
  • Lasts several minutes rather than hours
  • Improves after stopping the activity that triggers it
  • May respond to drugs such as nitroglycerin
  • Can remain relatively unchanged for months or years
  • Results from temporary event related to blocked off circulation to the heart rather than permanent damage to the heart

The underlying coronary disease, however, can still progress over time.

A sudden change in the pattern of chest pain should therefore not automatically be assumed to be “stable angina.”

Symptoms of Chronic Stable Angina

Symptoms vary from person-to-person

Common symptoms include:

  • Pressure in the chest
  • Tightness in the chest
  • Chest heaviness
  • Squeezing or constricting discomfort
  • Burning chest discomfort
  • Aching behind the breastbone
  • Shortness of breath
  • Reduced exercise tolerance
  • Unusual fatigue during exertion
  • Pain or discomfort may radiate into the:
    • Left arm
    • Both arms
    • Shoulders
    • Neck
    • Jaw
    • Upper back
    • Upper abdomen

Some people primarily develop shortness of breath or arm discomfort during exertion rather than obvious chest pain. 

What Triggers Stable Angina?

Common triggers include:

  • Walking rapidly
  • Running
  • Climbing stairs
  • Walking uphill
  • Heavy lifting
  • Vigorous exercise
  • Emotional stress
  • Anxiety or excitement
  • Exposure to cold weather
  • Walking against strong wind
  • Large or heavy meals
  • Physical activity shortly after eating
  • Sexual activity in susceptible individuals

Basically,  exertion, emotional stress, meals, cold weather and wind are all potential triggers

What Causes Chronic Stable Angina?

1. Atherosclerotic coronary artery disease – the most common cause. 

Atherosclerosis occurs when plaques develop within the coronary arteries resulting in narrowing of the artery. Even though the artery becomes narrowed, blood flow may still be adequate at rest, however, during exercise, the heart requires much more oxygen. If blood flow within these arteries cannot increase sufficiently, the heart muscle is unable to get enough oxygen and angina may develop.

2. Coronary microvascular dysfunction

Not every case of angina is a result of an obstructive coronary artery lesion. The very smaller blood vessels supplying the heart may also function abnormally and when this happens, a person can develop a condition known as microvascular angina, coronary microvascular dysfunction, or Ischemia with non-obstructive coronary arteries, or INOCA

3. Coronary artery spasm

This is a temporary constriction of a coronary artery that reduces myocardial blood flow and occurs due to a vasospasm. It is important to note that vasospasm and atherosclerosis may coexist.

4. Increased myocardial oxygen demand

Any activity or condition that makes the heart work significantly harder may worsen angina in someone with impaired coronary circulation.

Examples:

5. Reduced oxygen delivery

Angina may occur or become worse when the blood’s ability to deliver oxygen is impaired due to other underlying conditions such as anemia, low blood oxygen, certain types of lung disease.

Risk Factors for Chronic Stable Angina and Coronary Artery Disease

Important risk factors include:

Modifiable risk factors:

  • Cigarette smoking or exposure to tobacco smoke
  • High LDL cholesterol
  • Low HDL cholesterol
  • High blood pressure
  • Diabetes
  • Insulin resistance
  • Obesity, especially abdominal obesity
  • Lack of physical activity and exercise
  • Poor diet (excessive saturated fat, etc)
  • Chronic excessive calorie intake
  • Uncontrolled blood glucose

Non-modifiable risk factors:

  • Increasing age
  • Family history of premature cardiovascular disease
  • Genetic predisposition
  • Previous coronary artery disease
  • Previous heart attack
  • Previous coronary stenting or bypass surgery
  • Risk-factor management is a major component of contemporary chronic coronary disease treatment.

Stable Angina vs. Unstable Angina

This distinction is extremely important.

Stable angina usually:

  • Has predictable triggers
  • Occurs at a similar level of exertion
  • Improves with rest
  • Has a consistent duration and intensity

Seek urgent medical evaluation when chest pain:

  • Occurs unexpectedly at rest
  • Is significantly more severe than usual
  • Lasts longer than the person’s normal episodes
  • Is occurring progressively more frequently
  • Occurs with less exertion than previous episodes
  • Does not respond as expected to nitroglycerin
  • Is associated with other symptoms such as sweating, fainting, severe breathlessness, nausea or extreme weakness

A change from a previously stable pattern can indicate an acute coronary syndrome or myocardial infarction and should not be treated at home with supplements or herbal remedies.

Management of Chronic Stable Angina

Treatment in western medicine generally has two separate objectives:

  1. Reduce angina symptoms
  2. Reduce cardiovascular risk and prevent heart attack, stroke and cardiovascular death

Both of these are accomplished with the use of prescription medications such as nitroglycerin, beta-blockers, calcium-channel blockers, antiplatelet medications, statins, diabetes medications. It is also treated with the use of percutaneous coronary intervention (stents) or bypass surgery (CABG).

Natural therapies should be considered adjunctive options rather than substitutes for cardiology evaluation and treatment.

Natural Remedies For Chronic Stable Angina

Several lifestyle interventions have strong evidence for cardiovascular health, while certain Ayurvedic herbs have promising but substantially more limited evidence.

1. Arjuna – Terminalia arjuna

Arjuna is an Ayurvedic medicinal herb that has been used for treating heart disease for thousands of years.  In clinical research, Arjuna has demonstrated both rehabilitative and prophylactic protection in cardiac failure as well as reduced cardiac hypertrophy and fibrosis. Ayurvedic doctors frequently recommend this herb in practice for both cardiac diseases as well as those who have just recently had a heart attack. It appears to help strengthen the cardiac muscles and improve cardiac function. However, there are very specific ways to use Arjuna and it should not be used without proper supervision of an Ayurvedic doctor.

In a comparative clinical trial, Arjuna was found to have similar effects to that of a common drug known as isosorbide mononitrate for treating patients with chronic stable angina (see study). 

Compared with placebo, Arjuna was associated with:

  • Reduced frequency of angina
  • Reduced rescue nitrate consumption
  • Increased treadmill exercise duration
  • Less exercise-induced ST-segment depression
  • Faster recovery after exercise
  • Exercise duration increased from approximately 4.76 minutes during placebo treatment to 6.14 minutes during Arjuna treatment.

In clinical trials, this herb has been effectively used for:

– Reducing Ischemic Mitral Regurgitation (see study)
– Increasing Left Ventricular Ejection Fraction (see study)
– Reducing Blood Pressure & Cholesterol (see study)
– Reducing Cardiac Mass (see study)

2. Abana by Himalaya

Abana is a polyherbal Ayurvedic formulation produced by Himalaya for managing cardiovascular disease.

It has historically been marketed for cardiovascular support and has been studied for:

  • Ischemic heart disease
  • Angina
  • Hypertension
  • Lipid abnormalities
  • Ventricular function

In a randomized double-blind placebo-controlled trial, Abana was found to reduce frequency of angina, severity of angina, improved left ventricular ejection fraction, reduced myocardial oxygen demand indices, and reduced diastolic blood pressure in patients with ischemic heart disease including patients with mild hypertension (see study)

3. Ajwain – Carom Seeds

Ajwain, also known as carom seeds, is an Ayurvedic and South Asian medicinal spice obtained primarily from Trachyspermum ammi. Older medical literature also frequently uses the botanical name Trachyspermum copticum.

Ajwain contains several biologically active compounds such as thymol, carvacrol, p-Cymene, γ-Terpinene, and other volatile oils and phenolic compounds

In a double-blind, randomized, placebo-controlled clinical trial, researchers reported that patients receiving T. copticum demonstrated a significant improvement in anginal signs and symptoms compared with placebo (see study).

The symptoms monitored by researchers included:

  • Chest pain
  • Chest tightness
  • Difficulty breathing
  • Nausea
  • Light-headedness
  • Anxiety

The researchers also reported improvement in lipid profile in the ajwain group and no significant differences in routine safety assessments before and after treatment. It was concluded that Trachyspermum copticum extract significantly improved symptoms in patients with stable angina.

4. A Heart-Healthy Dietary Pattern

It is important to note that dietary intervention demonstrated considerably stronger cardiovascular benefits than most supplements.

A healthy, cardioprotective diet would primarily include:

  • Vegetables
  • Fruits
  • Beans and legumes
  • Nuts
  • Seeds
  • Whole grains (although this is widely debated)
  • Extra virgin olive oil
  • Fish where appropriate
  • High-fiber foods
  • Minimally processed foods

While limiting or avoiding:

  • Trans fats
  • Highly processed foods
  • Excess refined carbohydrates
  • Excess saturated fat
  • Processed meats
  • Excess sodium
  • Sugar-sweetened beverages

5. Regular Physical Activity

Exercise improves numerous cardiovascular risk factors.

Potential benefits include:

  • Improved endothelial function
  • Lower resting blood pressure
  • Improved insulin sensitivity
  • Improved aerobic fitness
  • Improved lipid metabolism
  • Reduced visceral fat
  • Improved vascular function
  • Improved quality of life

A combination of aerobic and resistance exercise may be very beneficial as well as cardiac rehabilitation for cardiac patients.

People who experience angina should always have a very individualized exercise program that focuses on gradual improvement and that does not intentionally exercise through chest pain.

6. Weight Management

If a person is overweight, gradual weight reduction can improve:

  • Blood pressure
  • Insulin resistance
  • Blood glucose
  • Triglycerides
  • Systemic inflammation
  • Physical capacity
  • Overall cardiovascular risk

Don’t underestimate the benefits of losing excessive weight. Even a modest reduction in weight that is sustained has the potential to produce clinically meaningful improvements in cardiovascular and metabolic health.

Lastly, it is very important to stop smoking and consuming excessive amounts of alcohol. Both of these substances are associated with numerous detrimental effects on one’s cardiovascular and metabolic health. 

In addition to this, stress management is non-negotiable. Of course, the causes of stress cannot always be avoided, but engaging in activities that help reduce the effects of stress can meaningfully improve your overall health. 

Useful stress-management techniques may include:

  • Meditation
  • Slow breathing exercises
  • Yoga
  • Mindfulness
  • Relaxation training
  • Adequate sleep
  • Psychological counseling when appropriate
