Introduction
There is a spectrum of diseases concerning the heart and associated blood vessels. Those diseases are collectively categorized as cardiovascular diseases (CVD). Getting rid of the condition is impossible once a person is diagnosed with cardiovascular disease. The conditions persist throughout an individual's lifetime, and on the go, it precipitates various health challenges and complications. Cardiovascular diseases can bring about alarming complications that can threaten one's life. However, various preventive strategies are employed to tackle the condition. Cardiovascular disease incidence is increasing daily, and a recent survey reports that CVS disease holds the red flag of the highest death rate among other illnesses.
What Are Cardiovascular Events?
The complications in the heart and blood vessels precipitated by pre-existing cardiovascular disorders are generally coined by the term cardiovascular events. It can be any eventful happening that impacts and impairs the functions of the heart. Certain studies have revealed that more than 30 percent of cardiovascular events are reported in individuals with known and identified cardiovascular illnesses. There comes the role of prompt treatment and preventive strategies for tackling cardiovascular events. Lack of proper preventive measures and ignorance often pave the way for grave cardiovascular events, which can risk one's life. However, with prompt treatment and effective preventive strategies, patients with cardiovascular conditions can lead a quality life.
What Are Different Cardiovascular Diseases?
There is a wide range of cardiovascular diseases. A few of the frequently reported and routinely encountered cardiovascular diseases include the following:
1. Coronary Artery Disease (CAD): Coronary artery is the chief blood vessel responsible for maintaining the supply of oxygen-rich blood to the heart muscles. Just like other cells in the body, the heart muscles constantly demand blood and oxygen. So when the coronary artery develops some disease, it can directly impact the blood flow to the cardiac musculature (heart muscle). CAD primarily develops in response to the piling up of certain materials, like fat, calcium, immune cells, and many more, onto the walls of the coronary arteries. These deposits form a plaque-like layer on the inner aspect of the artery, which restricts and narrows the diameter of the artery lumen through which the blood is supposed to flow. Some manifestations of coronary artery disease are short breaths, chest pain, trouble with strenuous physical activities, and fatigue.
2. Peripheral Arterial Disease (PAD): It is similar to coronary artery disease except for the involved artery. In peripheral arterial disease, the arteries that nourish the peripheral parts of the body, like the legs, develop atherosclerosis, which in turn restricts and compromises the blood flow to that area. Noticeable discoloration and muscle cramps are the frequently encountered manifestations of peripheral arterial disease. A pronounced collapse in the blood flow may bring about ischemia (cell death), which may sometimes demand amputation (surgical removal) of the involved leg.
3. Cerebrovascular Diseases: The blood vessels responsible for nourishing the brain cells are involved in cerebrovascular disease. Hypertension (boosted blood pressure) is a known condition that potentiates the likelihood of developing cerebrovascular diseases. Changes in the inner aspect of the blood vessel wall considerably restrict the blood flow through the vessel, which compromises the brain cells' nourishment. These are then precipitated in the form of subarachnoid hemorrhage (blood gathering within the brain space), stroke (cessation of nourishment to brain segment), and transient ischemic attack (brief check on brain blood flow).
4. Congenital Heart Disease: This is a group of heart disorders where the affected individual develops the defect by birth. It elicits a wide range of symptoms and is primarily based on the type and severity of the cardiac defect present in that particular person. Being an inborn defect, it is often identified in the childhood period itself. But in rare cases, the child may remain free of obvious manifestations, further delaying the diagnosis.
What Are the Various Strategies Employed for the Secondary Prevention of Cardiovascular Events?
Secondary prevention is mainly aimed at individuals who are either already detected with active cardiovascular diseases or have priorly developed episodes of cardiovascular events. Hence secondary prevention targets the population vulnerable to developing complications of cardiovascular diseases or events. Such classes of population are denoted as high-risk groups. Some of the promising strategies for secondary prevention of cardiovascular events include the following:
-
Early Identification of Risk Factors: Risk factors are a certain parameter that makes one susceptible to the disease. Cardiovascular diseases are backed by various risk factors, which contribute to the development of the condition in an individual. The more risk factors, the higher the possibility of acquiring the disease. Spotting out the risk factors for each individual is essential for tackling the condition's progression. Some of the risk factors can be revised and modified. Early identification and alteration of the potent risk factors is a great way to slow down the pace of disease progression, and it also checks the development of complications like a heart attack (blood flow termination to part of the heart) and stroke.
-
Early Diagnosis: The time of diagnosis of cardiovascular disease is of prime importance. Early diagnosis helps to shut out the severity of the condition. Once cardiovascular disease brings about permanent impairment in the body, it entails extensive and explorative treatment options for tackling the condition. Even then also, the permanent impacts cannot be altered and rectified. Early diagnosis checks unrepairable impairments in the body.
-
Statin Therapy: Cardiovascular diseases are often evoked and triggered by an enhanced cholesterol level in the blood. Over time, this boosted cholesterol in the blood gets piled up over the blood vessel creating a straightforward way for cardiovascular diseases. Hence keeping track of the cholesterol level and maintaining it within the healthy limit is crucial for the secondary prevention of CVD. Statin therapy is employed to control cholesterol levels, offering greater control over cardiovascular events' precipitation.
-
Beta-Blocker Therapy: Beta blockers are known for their effects on the cardiovascular system and are routinely advised for tackling enhanced blood pressure and heart rate. It calms down the heart and thereby brings down the rising oxygen demand.
-
Aspirin Therapy: Aspirin is advised in low doses for patients with known cardiovascular disease to check blood clot formation. CVDs carry the risk of forming unwanted blood clots within the vessels. These blood clots can impair the patent blood flow through the vessel, bringing cardiovascular complications.
-
Lifestyle Interventions: Therapeutic interventions can bring favorable results for cardiovascular patients when coupled with necessary lifestyle alterations. Weight management within healthy limits can be achieved by bringing about necessary changes in the dietary pattern. The intake of sodium ions should be restricted as it is closely associated with hypertension. Withdrawal from smoking brings down the burden on the heart and blood vessels.
Conclusion
Cardiovascular events can be dealt with through three preventive approaches - primary, secondary, and tertiary. Out of the three levels of approaches, the secondary level holds the upper hand over the others. Secondary preventive strategies are more economical and accessible for the patients rather than the extensive surgical approach of the tertiary level. Prompt adherence to secondary preventive interventions offers considerable protection for unrepairable cardiovascular impairment, enhancing the quality of life. It helps the person to live with the condition without precipitating life-threatening complications.
