Cardiovascular disease


Cardiovascular disease is the leading cause of death worldwide, and is closely interconnected with other cardiovascular, renal and metabolic (CVRM) conditions.1,2




What is cardiovascular disease? 


Approximately 523 million people across the world live with cardiovascular (CV) disease, often with declining CV health.3 Not only is CV disease the leading cause of death worldwide,1 it is also closely connected to other cardiovascular conditions.2

Coronary artery disease (CAD), is a chronic and persistent condition in which the arteries that supply the heart with blood are narrowed.4,5 Atherosclerotic plaque, a build-up of deposits of fatty material, cholesterol, cellular waste products and other substances, accumulate in the coronary arteries, obstructing the blood flow to the heart muscle.5 The plaque can cause partial or complete blockage of blood supply to the heart muscle, which can cause a heart attack.4,5

For those who survive a heart attack, it may often be the start of a journey into declining cardiovascular health. Over 30% of those who have had a heart attack go on to have a subsequent attack, stroke or death within the first year, underlining the importance of early diagnosis, developing treatments to reduce or stop coronary heart disease progression, and addressing uncontrolled risk factors.6



Cardiovascular disease news and stories





Addressing residual risk of cardiovascular disease 


Why is hypertension called a silent killer? 
 

Hypertension, or high blood pressure, is a common condition that relates to increased force of the blood pushing against the artery walls. It is sometime referred to as a silent killer as patients frequently do not experience obvious symptoms, although the condition is actively deteriorating the overall health of the individual:10

  • High blood pressure can lead to damage in multiple organs (this is called “end-organ damage”), which is often associated with the heart, as your heart needs to work harder to pump blood.10
  • Other organs can also be impacted, including your kidneys because the small vessels in the kidneys are affected, your eyes, and even your brain vessels.10,11


Normal blood pressure is defined as 120 mmHg or less for the systolic measurement, and 80 mmHg or less for the diastolic measurement.13 People with hypertension continually have blood pressure levels higher than those, although some people might have short-term elevations during certain activities such as exercise.  

Individuals with hypertension are considered to have a chronic condition and require several interventions to keep their blood pressure levels in the proper range. However, not all people respond to treatment in the same way. Some persons continue to present with elevated blood pressure despite lifestyle changes and taking medication, and this is known as uncontrolled hypertension (uHTN).14 Then there is a smaller group of patients whom, despite the concurrent use of three or more antihypertensive medications from different drug classes, are unable to normalise their blood pressure. This situation is known specifically as resistant hypertension (rHTN).15


Treatment-resistant hypertension (rHTN) impacts over 50 million patients

Addressing dyslipidaemia as a high residual risk


Dyslipidemia is defined as an abnormally high concentration of lipids in the blood and is associated with both lifestyle causes as well as genetic disorders. The key clinical indicators of change in the lipid profile include hypertriglyceridemia, reduced high-density lipoprotein (HDL) cholesterol level, and elevated small dense low-density lipoprotein-cholesterol (LDL-C) particles.18

High levels of LDL-C is estimated to cause 2.6 million deaths worldwide every year.19 Present alongside other comorbidities, such as hypertension, dyslipidaemia is a key risk factor for cardiovascular disease.18 More effective therapies are needed as more than half of CVD patients at high-risk of a major secondary event still struggle to meet their LDL-C goals, despite taking a high-intensity statin. 20,21 We are exploring both genetic targets as well as comorbid disease drivers, such as obesity, with the aim of developing new medicines to treat dyslipidaemia, and related cardio-metabolic diseases.





Emergency setting care for people at risk of cardiovascular events



Millions of people across the globe are prescribed blood thinners, specifically direct oral anticoagulants (DOACs).22 Clinicians often prescribe these medicines for the prevention and treatment of thrombotic events, or in patients at high risk of developing a stroke due to an irregular heart rate (atrial fibrillation).22-25 Their usage is expected to continue to rise even more as cardiovascular (CV) disease remains a leading cause of death across the globe. 25

These medicines are intended to prevent blood from coagulating and forming clots, which can obstruct blood flow and potentially harm different organs in the body such as the heart. While DOACs are a potentially lifesaving, effective and reliable medication, they carry a small but significant risk of an uncontrolled or major bleed such as an intracranial haemorrhage (ICH), trauma or gastrointestinal (GI) bleed. This increased risk is linked to the blood’s lowered ability to clot. 23,24,26

Each year 2-4% of those prescribed the medicines will experience the uncommon complication of a major bleed.27 Anticoagulant-related bleeding may occur spontaneously or because of trauma, complications from invasive procedures, or other illnesses or conditions.28 Reversal of DOACs is critical to slow or stop a major bleed and take further medical interventions.28 Managing these major bleeds requires speed, efficiency and clear hospital protocols based on current guidelines. 30
