The pathophysiology of pulmonary heart disease (cor pulmonale) has always indicated that an increase in right ventricular afterload causes RV failure (pulmonary vasoconstriction, anatomic disruption/pulmonary vascular bed and increased blood viscosity are usually involved [1]), however most of the time, the right ventricle adjusts to an ...
Patients with left heart failure or hypoxemic lung diseases (groups II or III pulmonary hypertension) should not routinely be treated with vasoactive agents including prostanoids, phosphodiesterase inhibitors, or endothelin antagonists, as these are approved for the different condition called primary pulmonary arterial hypertension. [69]
This category reflects the organization of International Statistical Classification of Diseases and Related Health Problems, 10th Revision. Generally, diseases outlined within the ICD-10 codes I26-I28 within Chapter IX: Diseases of the circulatory system should be included in this category.
Once patients are symptomatic, they present with right heart dysfunction secondary to pulmonary hypertension and its consequent dyspnea, fatigue, chest pain and syncope. [9] Patients tend to have a poor cardiac status, with 60% having stage III-IV NYHA heart failure. [5]
On physical examination, the most prominent features are due to the development of right-sided heart failure. These can include a raised jugular venous pressure, ascites, left parasternal heave and a tender, enlarged liver on palpation. [3] On inspection, patients may be chronically ill, cyanotic, cachectic and occasionally jaundiced. [citation ...
An important potential finding with echo is McConnell's sign, where only the RV apex wall contracts; [7] it is specific for right heart strain and typically indicates a large PE. [8] On an electrocardiogram (ECG), there are multiple ways RV strain can be demonstrated. A finding of S1Q3T3 [b] is an insensitive [10] sign of right heart strain. [11]

In addition, hypertension precedes heart failure in 90% of cases, [7] and the majority of heart failure in the elderly may be attributable to hypertension. [17] Hypertensive heart disease was estimated to be responsible for 1.0 million deaths worldwide in 2004 (or approximately 1.7% of all deaths globally), and was ranked 13th in the leading ...
