Several factors contribute to the development of resistant hypertension. Lifestyle choices, such as consuming a high-sodium diet, obesity, and excessive alcohol intake, are known to exacerbate the condition. High sodium levels lead to water retention, which increases blood volume and, consequently, blood pressure. Obesity is associated with increased vascular resistance and changes in kidney function, both of which can elevate blood pressure. Excessive alcohol consumption can also raise blood pressure by stimulating the sympathetic nervous system, leading to vasoconstriction.
In addition to lifestyle factors, certain medications can interfere with blood pressure control, leading to resistant hypertension. Nonsteroidal anti-inflammatory drugs (NSAIDs) and some over-the-counter drugs are common culprits. These medications can reduce the effectiveness of antihypertensive drugs or directly increase blood pressure. Moreover, secondary causes such as kidney disease, primary aldosteronism, and other hormonal disorders can contribute to this condition.
Diagnosing resistant hypertension requires ruling out pseudoresistance, which may occur due to improper blood pressure measurement techniques or non-adherence to medication regimens. Once true resistant hypertension is confirmed, treatment strategies typically involve lifestyle modifications, such as reducing sodium intake and weight loss, optimizing medication regimens, and addressing any underlying secondary causes.
For some patients, advanced treatments like renal denervation, which disrupts nerve signals to the kidneys, or baroreceptor activation therapy, which stimulates receptors in the arteries to lower blood pressure, may be necessary. Managing resistant hypertension is crucial because it significantly increases the risk of cardiovascular events, including heart attacks and strokes. Regular monitoring and a comprehensive approach to treatment are essential to improving patient outcomes in this challenging condition.
