What Is Angina?

Angina (an-JI-nuh or AN-juh-nuh) is chest pain or discomfort that occurs when an area of your heart muscle doesn't get enough oxygen-rich blood. Angina may feel like pressure or squeezing in your chest. The pain also may occur in your shoulders, arms, neck, jaw, or back. It can feel like indigestion.

Angina itself isn't a disease. Rather, it's a symptom of an underlying heart problem. Angina is usually a symptom of coronary artery disease (CAD), the most common type of heart disease.

CAD occurs when a fatty material called plaque (plak) builds up on the inner walls of the coronary arteries. These arteries carry oxygen-rich blood to your heart. When plaque builds up in the arteries, the condition is called atherosclerosis (ATH-er-o-skler-O-sis).

Types of Angina

The three types of angina are stable, unstable, and variant (Prinzmetal's). Knowing how the types are different is important. This is because they have different symptoms and require different treatment.

Stable Angina

Stable angina is the most common type. It occurs when the heart is working harder than usual. Stable angina has a regular pattern. If you know you have stable angina, you can learn to recognize the pattern and predict when the pain will occur.

The pain usually goes away in a few minutes after you rest or take your angina medicine.

Stable angina isn't a heart attack, but it makes a heart attack more likely in the future.

Unstable Angina

Unstable angina doesn't follow a pattern. It can occur with or without physical exertion and isn't relieved by rest or medicine.

Unstable angina is very dangerous and needs emergency treatment. It's a sign that a heart attack may happen soon.

Variant (Prinzmetal's) Angina

Variant angina is rare. It usually occurs while you're at rest. The pain can be severe. It usually happens between midnight and early morning. This type of angina is relieved by medicine.


It's thought that nearly 7 million people in the United States suffer from angina. About 400,000 patients go to their doctors with new cases of angina every year.

Angina occurs equally in men and women. It can be a sign of heart disease, even when initial tests don't show evidence of CAD.

Not all chest pain or discomfort is angina. A heart attack, lung problems (such as an infection or a blood clot), heartburn, or a panic attack also can cause chest pain or discomfort. All chest pain should be checked by a doctor.

Angina and Enzyme Therapy

What Cardiovascular Disorders Are Helped With Enzyme Therapy?

According to past research, enzyme therapy can help many cardiovascular disorders, including the following conditions:


  • Angina pectoris
  • Arteriosclerosis
  • Atherosclerosis
  • Coronary heart disease
  • Poor blood circulation
  • Degenerative inflammatory processes (both acute and chronic)
  • Eczema (as a result of a cardiovascular disorder)
  • Embolism
  • Endarteritis Obliterans
  • Hematomas
  • High blood pressure
  • Intermittent Caudication
  • Occlusive arterial diseasePhlebitis
  • Post-infarct healing process stimulation
  • Post-thrombotic syndrome
  • Raynaud's diseaseScleroderma
  • Smoker's and diabetic circulatory diseases
  • Stroke prevention
  • Thromboangitis obliterans
  • Varicose Ulcers
  • Atherosclerosis
  • Swelling (edema)
  • Thrombosis
  • Vasculitis
  • Occlusive arterial disease

Enzyme therapy is used to treat those cardiovascular disorders that result from "sticky" blood and blood dots. If you are to remain healthy, your blood must maintain a constant dynamic balance between its ability to remain liquid and free-flowing and its ability to form blood clots to keep you from bleeding to death in the event of an injury. If blood can't clot, tissues can't heal. But excessive bleeding can cause death. This is what can happen to people suffering from hemophilia because their blood lacks the ability to coagulate.

On the other hand, if your blood dots too easily, life threatening clots can form in your blood vessels, inhibiting circulation, and sometimes breaking free and causing heart attacks (when they reach the heart) or strokes (when they reach the brain). Cholesterol and other fatty materials may collect around the dotted deposits in the blood vessels. When this pathological condition develops, it is called hardening of the arteries or atherosclerosis.

It is critical to maintain a proper equilibrium between blood clotting and blood liquefaction. Unfortunately, a disturbance in this equilibrium is probably the most common source of illness and death in this country. In fact, one American dies every 33 seconds from cardiovascular disease, a condition that is largely preventable.

Every day, the body produces about two grams of fibrin the glue needed for coagulation. The body uses fibrin to seal wounds and to coat the internal walls of blood vessels. This coating protects the delicate vessel wall linings from damage by any passing particles and also smoothes any rough spots in the vessel walls. This assures an even, rather than a sporadic or disturbed, blood flow. The body constantly produces a steady supply of fibrin so it will have enough on hand in the event of an emergency (for instance, if you were to cut your finger).

For safety reasons, fibrin is present in the bloodstream in its inactive form, as fibrinogen. If a need arises, a series of reactions (triggered by enzymes) is put into play. First pro­thrombin (the precursor of the enzyme thrombin) is activated and changes to thrombin. Then the thrombin converts fibrinogen to fibrin, which forms a clot. When the clot is exposed to air, it dries out and forms a hard protective scab.

Fortunately, the body also has a protective mechanism to keep all of this fibrin from accumulating on the vessel walls (interrupting blood flow) or from being deposited in the wrong places. This "safety catch" is the enzyme plasmin (which exists in the blood as the proenzyme plasminogen). Plasmin dissolves clots through a process called fibrinolysis (the lysing or cutting of fibrin), and thus maintains blood flow equilibrium.

Even with all the built-in protective mechanisms, some­ times something goes wrong. Cardiovascular diseases occur when the blood becomes too sticky (thick blood is the most frequent accompanying symptom of fatal heart and vascular sys­ tem disorders). This sticky blood can occur from excessive fib­ rin production. But it can also occur if there is an error in plasmin activation and an insufficient amount of fibrin is broken down. This can lead to blood flow problems in the arteries and veins, as well as other areas of the body (including the tear duct and the mammary and salivary glands).

Unfortunately, as we age, our plasmin levels decrease. By the age of 60, we only possess a fraction of the plasmin we had when we were young. This means that blood flow is more sluggish, toxic debris remains in the vessels, and the vessels become narrower and harden, increasing the risk of a heart attack or stroke.

Beginning Symptoms Of Heart Disease, Stroke and Cardiovascular Disease.
Symptoms of a cardiovascular disease will vary depending on the specific condition. However, some of the most frequent symptoms are high blood pressure, elevated cholesterol, fatigue, and other effects of reduced circulation.

Is Enzyme Therapy The Answer?

Numerous studies have demonstrated that one of the best ways to dissolve large clots is with the help of enzymes. A number of enzymes are currently used (primarily in a hospital setting) as thrombolytic and fibrinolytic agents, including brinase (a protease from Aspergillus oryzae); streptokinase (from bacteria), and urokinase (from human urine). Recently, an Oregon man suffered a stroke and had no signs of brain activity. Treatment with the enzyme urokinase (administered directly into the area of the blood clot), was started nine hours after his stroke began (as a "last-ditch" effort). Not only did he regain consciousness, he also regained the ability to move his arms and legs (remember, stroke is one of the leading causes of adult disability). He subsequently went through six weeks of rehabilitation and is now home but is continuing physical and speech therapies.

Maintaining proper enzyme levels in the blood can also help prevent cardiovascular disease. Research has shown that proteolytic enzymes can improve circulatory imbalances and help normalize the fibrinolytic equilibrium. Proteolytic enzymes increase the fibrinolytic activity of the blood and therefore normalize the equilibrium between blood clotting and the break-up of blood clots. The result is that deposits of fibrin are dissolved. The edema, swelling, and the pathologic condition is reduced or eliminated. Proteolytic enzymes.

Cardiovascular Disorders improve the blood fluidity and, therefore, improve blood flow. This improvement in circulation improves the supply of nutrients to tissues. Proteolytic enzymes are also natural inhibitors of inflammation (which can occur in the vessels because of clot formation).

Systemic enzyme therapy is used as supportive care to improve circulation and reduce any pain, swelling, and inflammation. Enzymes stimulate the immune system, help speed tissue repair, bring nutrients to the damaged area, remove waste products, and improve health.

Digestive enzyme therapy is used to improve the digestion of food, reduce stress on the gastrointestinal mucosa, help maintain normal pH levels, detoxify the body, and pro­ mote the growth of healthy intestinal flora, thus relieving the stress on the body's own enzymes. Digestive enzymes also serve as replacements for the body's pancreatic enzymes, leaving the pancreatic enzymes free to perform other functions in the body, such as improving circulation.

Serracor-NK and SerraRx 80 are two of the most effective systemic enzymes on the market today for cardiovascular diseases. For more information please refer to our Heart Disease page.
