Interventional Cardiology Innovations

Interventional cardiology is a field that has seen significant innovation over the years, aimed at improving patient outcomes, reducing complications, and advancing the capabilities of cardiologists to treat various cardiovascular conditions. Some of these include:

• Drug-eluting stents – these stents are coated with medication that helps prevent the re-narrowing of the artery after angioplasty. They have been successful in improving long-term outcomes for patients undergoing percutaneous coronary intervention (PCI).
• Bioresorbable vascular scaffolds (BVS) – unlike traditional stents that remain permanently in the artery, BVS are designed to be gradually absorbed by the body over time, leaving behind only the healed vessel. While their efficacy has been debated, they represent an innovative approach to coronary artery intervention.
• Transcatheter aortic valve replacement (TAVR) – TAVR is a minimally invasive procedure used to replace a diseased aortic valve without open-heart surgery. It has revolutionised the treatment of aortic stenosis, particularly in elderly and high-risk patients who may not be able to have a surgical valve replacement.
• Intravascular imaging – techniques such as intravascular ultrasound (IVUS) and optical coherence tomography (OCT) provide high-resolution images of the inside of blood vessels, allowing for better assessment of plaque morphology, stent apposition, and vessel dimensions during PCI procedures.
• Fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) – these physiological indices help to guide treatment decisions during PCI by assessing the functional significance of coronary artery stenosis, leading to more targeted and appropriate interventions.
• Left atrial appendage closure (LAAC) devices – these devices aim to reduce the risk of stroke in patients with atrial fibrillation who are unable to take anticoagulant medications.
• Percutaneous mitral valve repair – techniques such as the MitraClip allow for the repair of the mitral valve without having to have open-heart surgery, offering an option for patients with mitral regurgitation who are not able to have surgery.
• Renal denervation – this procedure involves the ablation of renal sympathetic nerves in order to reduce blood pressure in patients with resistant hypertension.

VR simulations can help patients manage stress, anxiety and depression, which are common risk factors for CVD. VR-based exercise programmes can also facilitate cardiac rehabilitation by providing immersive and engaging workout experiences.

Gene Therapy and Regenerative Medicine

Gene therapy involves the delivery of genetic material into a patient’s cells to treat or prevent disease. This genetic material can either replace faulty or missing genes, introduce new genes to combat disease, or regulate existing genes. The main goal of gene therapy is to correct the underlying genetic cause of a disease at the molecular level. Regenerative medicine aims to restore or replace damaged tissues and organs in the body by harnessing the body’s own repair mechanisms or by using stem cells, tissue engineering, and other advanced techniques. Unlike traditional medicine, which focuses on managing symptoms, regenerative medicine seeks to address the underlying cause of tissue damage and promote healing and regeneration. 

Gene therapy and regenerative medicine hold great promise for treating cardiovascular diseases. Some challenges still remain, including optimising gene delivery and expression, enhancing cell survival and engraftment, and ensuring long-term safety and efficacy. Continued research and clinical trials are essential in order to overcome these challenges and achieve the full therapeutic potential of these innovative approaches in cardiovascular medicine. Gene therapy is being used in the following ways:

• Targeted gene delivery – gene therapy involves the delivery of therapeutic genes into specific tissues or cells to correct genetic defects or modulate disease pathways. In cardiovascular diseases, this may involve delivering genes encoding for growth factors, cytokines or enzymes in order to promote tissue repair, the formation of new blood vessels, or inhibit inflammation and fibrosis.
• Viral vectors – viral vectors, such as adenovirus, adeno-associated virus (AAV), and lentivirus, are commonly used for gene delivery. However, safety concerns, including immune responses and potential insertional mutagenesis, have prompted the development of safer and more efficient vector systems.
• Non-viral vectors – non-viral vectors, such as liposomes, polymers and nanoparticles, offer alternative gene delivery platforms with potentially lower immunogenicity and reduced risk of adverse side effects. However, their efficiency in transducing target cells remains a challenge.
• Clinical trials – several clinical trials have explored the safety and efficacy of gene therapy for cardiovascular diseases, including gene transfer for ischaemic heart disease, heart failure and peripheral artery disease. While some trials have shown promising results, challenges have also been identified.

Lifestyle Interventions and Preventive Strategies

Lifestyle interventions and preventive strategies can be important in reducing the risk of cardiovascular disease. This can include:

• Having a healthy diet – including a diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats such as those found in nuts, seeds and olive oil. A healthy diet also includes limiting your intake of saturated fats, trans fats, cholesterol, sodium and added sugars.
• Regular exercise – regular physical activity is important to help keep your heart healthy. There are many other benefits to regular exercise, including improving your brain health, reducing the risk of disease, strengthening bones and muscles, improving sleep quality, reducing high blood pressure, and reducing the risk of type 2 diabetes and several forms of cancer. It can also be a stress reliever and reduce symptoms of depression and anxiety.
• Weight management – maintaining a healthy weight through a combination of a balanced diet and regular exercise will help to keep your heart healthy. Obesity is a major risk factor for CVD, so weight management is crucial.
• Stopping smoking – smoking is a significant risk factor for CVD, and stopping can substantially reduce the risk.
• Limiting alcohol consumption – excessive alcohol intake can raise blood pressure and contribute to other CVD risk factors.
• Stress management – stress management techniques such as mindfulness, meditation, yoga or relaxation exercises can all help in reducing stress levels. Chronic stress can contribute to high blood pressure and other CVD risk factors.
• Regular health check-ups – things like blood pressure monitoring, cholesterol level testing and blood sugar testing can be helpful in monitoring the progression of CVD. Early detection and management of risk factors can prevent the development of CVD.
• Medication adherence – for individuals with existing CVD or high risk factors, adherence to prescribed medications such as statins, antihypertensive drugs and anticoagulants is essential for managing the condition and preventing complications.
• Education and awareness – the impact of lifestyle choices on heart health is important for people to understand. This includes educating people about the signs and symptoms of CVD and the importance of seeking medical attention promptly.
• Community support and resources – creating supportive environments that promote healthy behaviours, such as access to nutritious foods, spaces for physical activity, and support for people to stop smoking, can help people to achieve a healthy lifestyle.
