# Treatment methods for coronary heart disease
The choice of treatment depends on how severe the narrowing is, what symptoms someone has, and how the heart is functioning. In stable coronary heart disease, treatment usually begins with medications and lifestyle changes. In severe narrowing or acute heart attack, procedures may be needed to restore blood flow.
Medication treatment
Anticoagulants and antiplatelet agents
ProveniIncluded in official guidelines, or approved by EMA or FDA
Medications that thin the blood help prevent blood clots from forming in narrowed blood vessels. Acetylsalicylic acid (aspirin) and clopidogrel are standard treatments and are often prescribed in combination, particularly after a procedure. These medications inhibit platelet adhesion and reduce the risk of heart and stroke.
Known side effects include gastrointestinal bleeding, bruising, and in rare cases allergic reactions.
Beta blockers
ProveniIncluded in official guidelines, or approved by EMA or FDA
Beta-blockers slow the heart rate and lower blood pressure, so the heart does not have to work as hard. They are particularly used when someone is recovering after a heart attack or with irregular heartbeat. They can cause fatigue, dizziness, or cold hands and feet.
ACE inhibitors and angiotensin II receptor antagonists
ProveniIncluded in official guidelines, or approved by EMA or FDA
These medications dilate blood vessels and lower blood pressure. They protect the heart from further damage and are widely prescribed after a heart attack or in heart failure. A known side effect is a dry cough (especially with ACE inhibitors). Some people experience dizziness or feel weak.
Statins
ProveniIncluded in official guidelines, or approved by EMA or FDA
Statins lower cholesterol in the blood and stabilize fat deposits in arteries. They are a cornerstone of treatment and are recommended for almost all patients with coronary heart disease. This medication class can cause muscle pain or stiffness and very rarely muscle inflammation.
Nitrates
ProveniIncluded in official guidelines, or approved by EMA or FDA
Nitrates dilate blood vessels and reduce the workload on the heart. They are used to quickly relieve or prevent angina (chest pain). Side effects are headaches, facial flushing, and very rarely a sudden drop in blood pressure.
Calcium channel blockers
ProveniIncluded in official guidelines, or approved by EMA or FDA
These medications slow the heart rate and dilate blood vessels. They can be used instead of or alongside other medications, especially when beta-blockers are not well tolerated. They can cause constipation, headaches, or fluid retention in the legs.
Newer cholesterol-lowering agents
ResearchediPositive results in clinical studies, not yet standard treatment
Medications such as PCSK9 inhibitors and bempedoic acid are being investigated for patients in whom statins are insufficient or not well tolerated. They have additional potential, but are not yet prescribed as standard treatment. Side effects are generally mild, but research into long-term effects is ongoing.
Anti-inflammatory agents
ResearchediPositive results in clinical studies, not yet standard treatment
Some studies suggest that chronic inflammation plays a role in coronary heart disease. Specific anti-inflammatory medications are in the study phase, but are not yet part of standard treatment. Further research is needed to properly assess benefits and risks.
Invasive procedures
Percutaneous coronary intervention (PCI) and stent placement
ProveniIncluded in official guidelines, or approved by EMA or FDA
In this procedure, a thin catheter is inserted through an artery in the arm or groin to the narrowed coronary artery. The narrowing is then pushed open and usually a stent (metal tube) is inserted to keep the vessels open. This is performed under local anesthesia and with X-ray guidance.
The procedure provides rapid symptom relief and reduces the risk of heart attack. Possible complications are bleeding at the puncture site, infection, vessel dissection (tear), or, very rarely, damage to the heart. After stent placement, long-term medication treatment is necessary.
Coronary artery bypass grafting (CABG)
ProveniIncluded in official guidelines, or approved by EMA or FDA
In this procedure, under general anesthesia, a healthy artery or vein from elsewhere in the body is connected around the narrowed coronary artery. This restores blood flow without removing the narrowing itself. The procedure is suitable for patients with multiple severe narrowings or when PCI is not possible.
Side effects and complications include wound infections, bleeding, arrhythmias, and very rarely stroke or pulmonary edema. Many patients experience pain after surgery and need weeks to months to recover.
Rotational atherectomy and laser atherectomy
ResearchediPositive results in clinical studies, not yet standard treatment
These newer techniques use rotation or lasers to remove calcified or hardened narrowings before a stent is placed. They are used particularly in complex cases. Studies are ongoing into their added value and long-term safety.
Supportive measures
Treatment of risk factors
ProveniIncluded in official guidelines, or approved by EMA or FDA
Controlling blood pressure, cholesterol, blood sugar, and quitting smoking are essential. Doctors provide guidance on healthy diet, physical activity, and stress relief. Psychological support can help when someone has difficulty with lifestyle changes or experiences fear after a heart attack.
Cardiac rehabilitation
ProveniIncluded in official guidelines, or approved by EMA or FDA
After a heart attack or surgery, many patients follow a rehabilitation program with supervised exercise training. This helps the heart gradually become stronger, reduces fear, and restores confidence in the body. Participation in cardiac rehabilitation is associated with better outcomes.
Psychological support and anxiety reduction
ProveniIncluded in official guidelines, or approved by EMA or FDA
Coronary heart disease is often accompanied by fear, depression, or post-traumatic stress, especially after a heart attack. Psychological help, cognitive behavioral therapy, or educational counseling can reduce these feelings. Research shows that information and animations can alleviate anxiety.
Experimental approaches
Regenerative therapies
ExperimentaliOngoing in study setting, outcome still unknown
Stem cell therapy and growth factor treatment are being tested in research for repair of heart muscle tissue after a heart attack. The goal is to restore damaged tissue or stimulate new blood vessel formation. This is not yet ready for clinical use.
Targeted drug research
ExperimentaliOngoing in study setting, outcome still unknown
Studies are investigating the potential of pharmacological interventions based on genetic profiling (lipoprotein(a) lowering, metabolic variants). This approach may in the future help tailor medicines better to patients, but is still in the research stage.
Coronary vasospasm therapy
ExperimentaliOngoing in study setting, outcome still unknown
For patients with coronary vasospasm (sudden contraction of the heart arteries), new treatments are being investigated, such as cardioneuroablation. This targets underlying causes and is still being evaluated.
